Just do your best
Hi - This is Bright-moral animal hotline. How can I help you?
Hallo there. My name is Abelii. I have this problem with a fruit tree standing nearby. Sometimes fruit falls of the tree and when the fruit hits the ground, it tumbles into a small hole. I can´t reach the fruit with my fingers in that small hole. Do you have any suggestion to what I could do, to get the fruit?
You can’t find a branch or something similar, that you can put into the hole and drag the fruit out?
I tried that, but it did not work. The fruit just slips back into the hole
Hmm – there might another solution. Recently some scientist made some tests with orangutans like you 1). Earlier, other scientists had been seen that crows could bend wires into hooks and use these as tools. Inspired by that, they wanted to test how good orangutans were to make tools from a wire.
Interesting – How was setup?
The scientist hid some food in tubes, where the orangutans could see it, but not reach the food in the tubes. Next to the tubes where some wire. Some of the orangutans figured out how to bend the wire and use the hook they had made, to drag out the food. Just like crows.
Cool – but what can I use that information for?
Well maybe the are some humans living close to you, where you can find some wire and make a hook.
Right you are. Not far from where I live, humans have a palm oil plantation. I should be able to find some wire there. Good idea. Just out of curiosity. Who was best at making hooks from wire? The orangutans or the crows?
Honestly, I think it was the crows. But you know – There will always be someone, who is better than you in certain skills. So, my advice to you is; Go out and do you best, and don’t worry about somebody doing it better than you.
Thanks for the advice – It makes sense. I will head down to the plantation and see if I can find some wire.
Step up – Stepfather
Hi- This is Jane from Bright Moral Animal hotline. What can I do for you?
Hi - This is Labiata here – I am a male bee of the kind called Ceratina nigrolabiata – sumsum.
Yes - I could nearly guess that. What is the reason you called us?
Well you see, we are a special kind of bees that pair up - two and two. This is unusual for bees- I know. But, I found this wonderful female bee, and now I want to move in at her place.
Wonderful – and is she okay with that?
Absolutely – she would love it. My problem is that she already has some kids, and I am a bit worried that she hangs around with other males.
I get your problem, and I will try to ease your worries.
That would be great – I am listening.
Just recently I read an article from some Czech scientists, who had studied your kind of bees out in the field 1). They had made some artificial nests by cutting some twigs, so the bees could enter the twig from the cut site. Off the nearly five hundred nests they made, almost 90 % of the nests were populated with a pair of bees, male and female.
Impressing – How did they test all those couples?
Good question – They followed the bees over a number of years. What the scientists saw was that the male bees protected the nest from ants and other insects, while the females went out for food. This was not so surprising.
No, I guess not. So, did any surprising things happen?
Yes, there did. The male bee usually only stayed for a weeks’ time and then left everything - also his kids. Shortly after a new male moved in. He would then take over the responsibility of all the kids. In only 10 % of the time did the males take care of their own kids. Mostly they took care of the other kids.
How did the scientists figure that out?
They made genetic tests of the parents and the kids, to figure out who belonged to who.
Wauv – and none off the couples stayed together?
Actually, in rare cases the male and female stayed together until the kids left home. On average all the males had 3-4 kids, but they seldom took care of their own.
Did the females need the males at all?
Yes, they did – Otherwise the female could not venture far away for food, without risking that the kids were taken by other insects.
I hope I can stick together with my girlfriend forever, but what if I can’t?
That is a good question and there is a high risk that it will not happen. My advice to you would be; Step up to the stepfather role – take care of the kids that are entrusted to you as were they your own, even though they are not. There is a good chance that another stepfather is taking good care of your kids.
Thanks for your advice – I will keep that in mind, when I take on the Step-father role.
I am glad to hear that– wish you all the best.

Hi this is Bright moral animal. I am Jane. What can I do for you?
This is Atta here. I belong to a group of ants called the leaf-cutters. What I have heard is that we go out in the woods and cut leaf’s which we bring back to the colony. I am very young, so I haven’t tried it yet. My worry is that nobody seems to be in charge of our work.
Hi Atta – well you don’t need to worry. Let me tell you why.
Please do – Jane.
Recently, there came an article, where some scientists studied different leaf cutter ants in both the laboratory and in the wild 1). In the laboratory they had made a big system with a pair of colonies of Atta vollenweideri leaf cutter ants, so they could do some tests. In one part of the system was the colony and in other parts were the fresh leaf’s, that the ants needed. In between were some tubes connecting the places.
Hmm what was the purpose in that?
Well the scientists tested how the ants behaved, when passing along the trails in the tube. They put 10 small papers across the path, which was 8 cm wide. If the papers laid flat on the path, the ants just passed over. If the papers contained added sugar-water the ants took the papers to the colony. If the papers had been drawn with a speed marker, the ants moved them to the side, possibly because of the solvent-odor. But that is not really the interesting part.
Okay what is the interesting part?
The scientist folded the unmarked small papers, so they were standing instead of being flat. Then the ants started moving the papers from the trail. If the paper was moved more than 5 mm, it was considered a removal. All this was seen either by a camera or by human eyes. The results were nearly the same. What do you think the result was?
I have no idea.
Fair enough – What was seen, was that the ants moved on average 8 papers clearing the trail within 30 minutes. Interestingly most ants just moved one paper, but a small group of approximately 20% moved on average nearly 3 papers each from the trail. This was regardless whether they were coming from the colony or going to the colony. Nearly the same experiments were carried out in the forest on the ant species Atta cephalotes. Again, the paper obstacles were removed. This was not done by the ants carrying leaves. The experiments were also simulated on a computer, where the simulated results fitted the obtained data. Do you know what the data indicates?
Damm, that is a hard question – again I have no idea.
Well the simple explanation is that the ants just removed the papers, when they encountered it, without having to be recruited by other ants or a boss. The ants, taking on average nearly 3 papers, might have been a special task force, but they also did the job on their own accord.
So, what are you trying to tell me?
Well Atta - my advice to you is; Don’t wait for orders, Take responsibility.
Okay - I understand what you are saying, and I will do my best to act responsible.

Hi This is
Bright-Moral-animal hotline. I am Jane.
What can I do for you?
My name is
Pan. My problem is that a friend of mine wants me to help him, but I am not
sure it is worth it.
give me some more details of the problem?
see, we have a fruittree nearby, where you can pick the low hanging fruits, just
standing on the ground. But when you do take a fruit, the branch becomes
lighter, and then it is hard to get the next fruit.
Can you not
climb onto the branch?
No, I am too
heavy for those branches. So, then my friend suggests that I pull down the
branch, and then he takes as many fruits as he can reach. But that takes time
and I am not patient. What if he takes all the fruit?
I get your
point. I just read about how some scientist tested some of your chimpanzee
friends (Pan troglodytes), which
might interest you 1). The chimps were very skilled, so they knew
how to read a lexigram, meaning they understood the meaning of pictures and
they were skilled in exchanging a token with a human to obtain food.
Cool – they
This time the game had changed slightly, so if a chimpanzee moved a token to
another ape in the next cage, it would obtain some more food in a bowl outside
the cage. And if the chimp in the other cage moved the token back to the first
ape, it would also get some food. When the apes continued this game, the amount
of food grew. But they did not get the food straight away. Not until one of the
chimpanzees passed the token to the human, but then the game stopped.
what you say is; as long as they passed the token, they got more food, but they
could not eat it straightaway. What if they were hungry?
well feed, and what they got, was sweet candy M&M´s. Very delicious. What
do you think happened?
they tried to get as much as possible.
The chimpanzees continued to pass the token to each other until the human
stopped adding M&M in their bowls. When chimpanzees figured that out, they
passed the token to the human and got their candy. The scientists also changed
the partners, so the chimpanzees engaged with other chimpanzees. Here the
scientists saw the same. The chimpanzees collaborated to get as much as
possible, without stopping.
scientist also tried the same experiment, where it was a machine that gave the
food, and the chimpanzees could stop the experiment by taking the bowl. Still,
the apes continued collaborating by transferring the token to each other until
the food stopped coming.
think I get the picture.
I guess you
do, so my suggestion to you would be; Collaborate to get the largest gain you
Thanks - I
will go out and get the fruits with my friend.
enjoy the fruit.

Hi This is Bright Moral Animal Hotline. What can I do for you?
Hi Sorry if I sound confused right now. I have this mystery. Maybe you can solve it. Blop blop
Maybe I can – Please tell me some more. What is the mystery about?
Well you see – I am fish – a cleaner fish. My friends call me Wras. Close to where I run my cleaner station, there is a cliff that is very flat and shiny. When I pass the cliff, it seems like there is a cleaner fish swimming in the cliff. Am I going crazy, or what is happening?
No don’t worry. You are not going crazy. It is actually your own reflection you see.
Really – I did not know that I could do that.
Well recently some scientists made an experiment on some cleaner fishes (Labrodides dimidiatus) 1) . Here they put a mirror in front of the fishes – like the cliff you have. First the fishes attacked the mirror because they thought it was an intruder. Then after a few days they started making funny movements, as if they were trying to figure out what was going on. And after 5 days they just spend a lot of time in front of the mirror. All this did not happen when the mirror was covered.
Maybe I should go and make funny movements in front of the cliff. Blop blop - How did the scientist figure out that the fishes knew they were watching them self?
Good question- Wras. They put a colored spot on the side of the fish. The spot could only be seen using the mirror. When the fish saw the spot in the mirror, they apparently knew that the spot was on the side of their body. This was seen, by the way the fishes tried to scrape off the spot by rubbing the color-spot on a cliff or on some sand.
Interesting – but maybe they could feel the spot.
Clever thought, but no. If the spot was color-less, the fishes did not try to remove it, because they could not see it in the mirror. Likewise, if there was no mirror, they did not try to move the colored spot. So, it seems that the cleaner fish realized they were watching them self. They were self-aware.
Cooool- I got to swim over to the cliff and check myself out. See how I look and make some funny moves.
Well I understand if you want to look more at yourself but let me just tell about a young guy named Narcissus, who was extremely beautiful. One day he stops at a lake and looks at his own reflection in the water. He can’t stop doing that, so he finally dies there and turns in to a flower.
Oh that was sad. What do you suggest then?
My advice to you would be; Don’t focus to much on how you look. Either you will get too absorbed in yourself and won’t get along with other fishes, or you just get depressed. But you can use the cliff to check that you don’t have any skin-infections.
Okidoki I get the picture – thanks for your advice. I am so happy, that I am not going nuts blop blop
You are welcome.
Cleaner wrasse pass the mark test. What are the implications for consciousness and self-awareness testing in animals?
Short cut or not
HI This is Bright-moral-animal hotline. I am Jane. What can I do for you?
Hi Jane, this is Ponera. I am about to grow up to become an ant-scout, and I need a piece of advice.
Okay – please tell me a bit about the work you are expected to do.
Well see – I must go out and look for termite colonies, which we can raid and bring the food back to our colony. Personally, I think I am quite smart, but also a bit lazy, so I like to make short cuts. But when I tell this to the older scouts, they smile at me, as if they now better. Should I just ignore them, or prove them that I am right?
There are many sides to this - Ponera. I assume you are a Megaponera analis ant, that goes hunting for termites. As an ant-scout, you are working on your own. You alone have to find the best way for the hunting party to take, in order to get to the termite colony. This is quite a responsibility, where you don’t want to waste your friends time and energy. You must find new trails all the time, because the old ones can’t be used, when the termites are gone.
True – That is why I think it is a good idea to make short cuts.
Hmm Not quite. Let me tell you about some experiments that were made recently in Cote d´Ivoiry 1). Here some scientist had studied some of your friends. They identified 8 colonies of M. analis. Then they cut the grass and scattered some hay in a 20 meter radius from the colony, so the surroundings look approximately the same for all the colonies.
What was the point in that?
Well you see, then the scientist monitored, which route the raids took to find the nests of the termites and measured how long time it took to get there. After having done this, they cut four “highways” in the grass 20 meters long and 30 cm in width, going either north, east, south and west. Again, the scientist monitored the path of the raid parties, as well as the time spend on going on these parties.
Cool, what was the outcome of that?
The interesting thing was that quite a number of the raid parties took the “high way”, at least part of the way, even though the route was longer. Can you guess why?
No - That does not make sense.
Well it does, because they saved time. The travelling speed was nearly twice as fast on the road as compared to the travelling speed in the grass.
Okay I get the point – I thinking.
Another interesting thing was that when the scientist did the same type of observation some weeks later, the “highways” were used twice as much as when the roads had just been made. So, the ants learned by experience, that there was a benefit in using the roads. This was not because the ants used pheromones to make a smell-track, like other ants do. Hunting ants don’t do that.
Okay – so what would you advise me to do as a scout ant?
My advice to you would be; Think, before you make a short-cut. Often short-cuts will be turn out to be a waste of time. Taking a longer route might actually be faster. When you are a young scout, this will probably happen from time to time, but you will gain experience as you do it several times, so don’t worry to much. You will get there.
Thanks for your advice. I will do my best and keep that in mind.

Feel unfairly treated
Hi Is this Bright moral animal hotline?
Yes, it is. What can I do for you?
My name is Cebus, and I have a bit of a problem; that is my temper. When I feel that something is unfair I get angry, which my friends find annoying. Should I just let unfairness pass, as nothing happened?
Good question. I assume that you are a capuchin monkey (Cebus apella) – right?
So true. HooHoo
Well a few years ago some scientist tested some capuchin monkeys on how they reacted to unfairness, or “inequity aversion” as they call it 1).
How did they do that?
Well the scientist had two monkeys, one in each cage. In front of the cages were 2 boxes with food. Only one of the monkeys – the so-called Operator, could reach the boxes and drag them to the cages, so they get the food. Two different situations were tested. One situation, where both monkeys would get the same food, and one situation where the operator would get less food than the other monkey.
Ooh dear what happened? I know I would get angry in the last situation.
Well that is actually what happened. When both got the same amount of food, there was no problem. The operator would drag the boxes to the caves. On the other hand, if there was less food in the Operators box, than in the other box, the operator would more often refrain from dragging the boxes to the cages. It would rather not have food, than give the monkey in the other cages extra food.
I totally get that. That would piss me off as well. I would rather starve.
Another interesting observation was that if there was no monkey in the other cages, the operator did not care, if there was more food in the other box. It would still drag the boxes to the cages, so that it could get the food. So, it was only when there was somebody in the other cage, that the operator got the feeling of unfairness.
Hmm that is funny, but I guess it makes sense. It is hard to feel unfairly treated if there is nobody to compare too. So, what you are saying is that it is okay for me to get angry in these situations?
Well partly. What I would say is this; You shall speak against unfairness, but I would add that you should speak in a way that makes the others listen and think. That does not happen if you just get angry and scream.
I get your point. Next time I feel unfairly treated, I will tell them why I feel unfairly treated, and hope that they can understand my point of view.
That is such a good idea. I wish you all the best.
Thank you for the talk.
You are welcome.

Warning friends and family
Hi - is this bright moral animal hotline?
It sure is. What can I do for you?
My name is Glodyt and I am a young chimpanzee. I would like to hear your opinion regarding my problem. My friends and family thinks that my pranks are dangerous, and that I should grow up - hohoho.
So, what do you do, to make them say that?
For example, if I see something dangerous, like a lion, I don’t say anything. Then I just wait and watch to see how scared they get. That is so funny.
Hmm that is not very nice of you. Actually, I don’t think you do it to make fun. I think you are scared, that by warning your friends and family, you risk that the lion might spot you. And that is a genuine risk.
Well - that might be partly true.
Would you like to be eaten by a lion, just because your friends did not warn you?
No, not really.
See you got to grow up and take responsibility.
Let me tell you what other Chimpanzees do. Some recent experiments have just been performed in the forests in Uganda 1) . Here, some scientist had set up some loudspeakers, which were used to play chimpanzee sounds. It could either be sounds from chimpanzees, that were peace full and resting, or from chimpanzees that were alert of a danger. They also put out a fake snake on the walking path, that the chimpanzees were using daily.
What was the point in that?
You see, when the scientist saw a chimpanzee passing on the path, they switch on the sounds, either “the resting sounds” or “the alert sounds”. Then a bit further down the path, the chimpanzee would pass the fake snake, and the scientist would note how the chimpanzee reacted.
Interesting – what happened?
It is interesting. It turned out, that if the
chimpanzee on the path, had heard “alert sounds“ from the loudspeakers, then
the chimpanzee would say a few loud “alert hoos” to warn the others. But if the
chimpanzee had heard “rest sounds” from the speakers, then it would make much
more “alert hoos” in the direction of the speakers, to warn its friends and
family of the danger of the snake apparently knowing that they were not aware
of the snake.
Okay I might get your point.
Good – My advice to you is; If you see danger, you warn your friends and family, even when it put yourself at risk. That is best for everybody in the long run.
Well thank you for your advice – I will think about it.

Hello This is Jane from Bright-moral-animal hotline. What can I do for you?
Hi Jane. You are talking to Nortus. I am in a bit of trouble. One of my legs hurts. Maybe it is broken. I don’t know how to go out and collect food. What do you think I should do?
Well if it is broken it might take some time to grow together. Hmm Where do you find food?
Maybe you already guessed it, but I am a rat and I live in the sewers of a big city. There is often food to be found, but I need to go and look for it.
Being a rat, is not so bad in your situation. A recent experiment was made by some scientist on rats (Rattus norvegicus) 1) . Here they tested how prone the rats were to exchange one favor with another favor. In this case the rats could exchange food for grooming or vice versa, grooming for food.
How did they do the experiment?
Great that you ask. When it came to the food-test, they would take a pair of rats, one in each cage. One rat would be the giver, and the other rat would be the receiver. Then the scientists would add some food on a stick. The giver-rat could not reach the food, but it could pull the stick, so that the receiver-rat would get the food. The scientist tested the grooming by adding a drop of salt-water on the neck of one of the rats, so that the rat could not remove it. This clearly annoyed the rat. The other rat, which in this test was sitting in the same cage, could groom the annoyed rat by removing the salt-water drop.
Hmm what was the result of that?
The interesting thing is that if the giver-rat had given food to the rat, that it had been paired up with, then it was much more likely that the giver-rat would be groomed by the receiver-rat, if the giver-rat had an annoying salt-drop on the back of its neck. Like wise if one rat had been groomed by the other rat in the pair, then the groomed rat was much more likely to give food to the rat that had groomed it.
Interesting – I think I see where you are leading me. What would your advice be?
I guess it is very obvious; If you do a favor for others, you are more likely to have the favor returned. So, find somebody who needs grooming, and you just might get some food in return.
This is definitely worth a try, rather than starving. Thank you for your help.
You are welcome.

Hi this is bright moral animal hotline. How can I help you?
Hi my name is Ponera
What can I do for you – Ponera?
Well you see. I am a young ant living in a big colony of ants. Up until now, I have been taking care of things in the colony, but that is about to change. Soon I will have to join the hunting party. We hunt termites, and usually we hunt in groups of 200 up to 600 ants, because the termites defend them self so well. Especially the soldier termites are tough and strong. My problem is; what is going to happen to me, if I get injured?
One good thing is, that you are lucky to be born in that ant colony, where everybody tries to help where it makes sense. A new scientific study has just been made on the ant specie named Megaponera analis 1), which I assume you belong to. Isn’t that correct?
Right you are. That is my kind.
Well in this study the scientists showed, that if a fellow ant was injured during the hunt, then the other ants would help the injured back to the ant colony, and even attend to their wounds by applying antimicrobial substances, to avoid an infection.
Really – that sounds great. Then I don’t need to worry so much.
Well honestly – not everybody gets help. If you seem to be dying, and can’t stand on your legs, then you don’t get any help. On the other hand, if you can stand, but walk very slowly, then your fellow ants will help you.
Hmm interesting- it makes you think, doesn’t it ? So, what is your advice to me?
Well, if you are uninjured during the hunt, then you should save the savable. Meaning you should save those of your injured friends that can survive. If you do get injured, like for example get a leg bitten off, then try to walk anyway. But don’t walk to fast even though you can. This will increase your change of getting help and treatment.
I will keep that in mind. Thanks for your advice and that little trick regarding slow walking.
You are welcome.

Get Smart – be social
Hi Is this Bright Moral animal hotline?
Hi Yes you got the right connection. I am Jane. How can I help you?
Krakra – well you see. I am magpie. My friends call me Cracticus. Right now, I am laying on my eggs. It won't take long before they hatch.
That sound fantastic. Congratulation.
True – But now I get this Mother-anxiety. How can I help them? Shall I protect them from other magpies and keep them in the nest? Or the opposite? What’s is going to become of my kids?
I guess that is classic worry for many mums, and dads for that matter. I assume that you want to know, what you should do to help the next generation.
Exactly – that is my issue. What advice can you give me?
Interestingly, there has just been published a study1) from western Australia on wild magpies, named Craticus tibicen dorsalis. Here the scientist looked at 14 groups of magpies, each being 3 to 12 individuals. They wanted to test, if animals living in larger groups, were brighter. For many years, scientists have thought that this might be the case, because living in a larger social complex environment might improve your intelligence, or select for those individuals, that are more intelligent.
Krakra that is fascinating.
Indeed, it is. The scientist tested the wild magpies for their general intelligence and memory, by hiding marshmallow. The magpies love marshmallows. They were hidden either behind some see-through plastic or below a lid on special board with many lids. The magpies could open the lid with their beaker. Marshmallow were hidden the same place several times to test the birds memory. What do you think the outcome was?
I don’t know krakra
Well it turned out that the magpies living in larger groups had a better performance than those magpies living in smaller groups. This could indicate a higher general intelligence. This correlation was not visible 100 days after fledging but came clear 300 days after fledging.
Hmm that gave me something to think about. I live in a small group.
That might be of concern. Interestingly the scientist also showed that the magpies, that did best in the performance tests, also had the highest reproduction success. Those, that were smartest, got the most fledglings pr. Year.
Kra-kra – so, what would you advise me to do with my kids?
My advice to you is; Socialize with others, it might enlighten you and your kids.
Thanks for your advice. I might think about moving, once the kids are fledglings.

Getting a new friend
Hi - It is Jane from Bright Moral Animal hotline – What can I do for you?
Hi Jane – my name is Canis. Vuff Vuff - I am moving to a new place, and I need some advice.
Sure – but may I ask - why are you moving?
Well as you might have guessed – I am a dog, also named Canis lupus familiaris. I have been living in a kennel since I was born, but now I am moving to a family with humans. This scares me a bit. I feel like I am out of my comfort zone. What if they do not like me?
I fully understand your worries about moving. But I might be able to help you with a trick. As you might know, dogs and humans have coexisted for many thousands of years. Very old cliff drawings confirm that1).
Wauw – thousands of years.
Yes -and during that time humans and dogs have gotten used to each other’s company, which is quite unusual for animal species. It even influences the way their hormone system reacts.
Really – in what way?
Good question – recently some scientist tested how dogs and their human owners affects each other’s hormone level. They were looking at the hormone – oxytocin2 ). It is also known as the love-hormone. For example, it has been found that the oxytocin level increases in both mothers and their baby´s, when they look at one another. The scientists speculated that the same might take place between a dog and its owner. They let dogs and their owners gaze at one another or touch each other for a short or a longer time. What the scientists found was that the level of oxytocin increased in the urine of both the dog and its owner, if they gazed a long time at one another. This did not happen when wolves and their owners gazed at one another. Even though wolves are a close relative of dogs as you self.
Very interesting – so what you say is that humans can affect my hormone level and I can affect theirs.
Yes – and what was also interesting was that, when the scientists gave female dogs a nasal dose of oxytocin, the dogs started gazing more at their owners. This did not work for male dogs. And actually, the hormone effect only takes place between the dog and their own human owner. Not between a dog and a human stranger.
Vuufff – so what is your trick?
Well my trick or advice to you is; If you want to make friends, start with a friendly gaze.
Thanks for the advice – I will try to gaze friendly at my humans – and hope that will get their hormones going.

Hi this is Bright Moral Animal Hotline. How can I help you?
Hi Hotline. I am a zebrafish – blop blop. My friends call me Dan.
That makes sense as your kind are also named Danio rerio. What is your problem - Dan?
Well – you see my friends are getting on my nerves and I would like to be on my own. Independent and free as a bird, as the saying goes. But they don’t seem to understand it. Should I just swim away from the crowd, the shoal?
Hmm I understand what you say. Some animals, actually prefers to live alone even tough others of their kind live in herds. For example, old elephant males like to live alone. But you are a zebrafish, and you get so much in return from your own kind. If you are in trouble, then it is soothing to be among your own friends. It calms you down.
Really? Sometimes I feel the opposite.
Well let me tell you about an experiment, which I read about recently1. Some scientist made some tests on zebrafish. They had an aquarium, which they had separated in two halves by a glass plate. On one side of the glass plate they had the zebrafish, that was to be tested for its behavior, the test-fish. On the other side of the glass plate they had either 0, 2, 4 or 8 zebrafish. Then they stressed the test-fish by adding a stressing substance to the water. Do you know what happens to you, when you get stressed - Dan?
Yes - I freeze. Stop moving around. That is not fun.
Exactly and it was the swimming pattern which, the researchers were looking at, by filming the test-fish. If the fish moved less and “froze”, then they knew that the test-fish was stressed. So, do you think it made a difference, whether there were fish on the other side of the glass-plate or not, when the test-fish was stressed?
Hmm I don’t know. Blop blop
Well, it was clear to see that the stressed test-fish moved a lot less, when there where nobody in the other chamber, as compared to when there were 2,4 or 8 fish. This means, that the test-fish was a lot more stressed, when it was alone as compared to the situation, where it could see fish on the other site of the glass. Even the smell of other zebrafish was enough to calm down the test-fish. So being alone is not good for a zebra fish. As Homo sapiens: No human is an island.
Do you mean to say that; No zebra fish is an island?
I guess that does not make sense for a fish to be compared to an island. What I mean to say is, that for some animal species, it is no good being alone. That also goes for zebrafish. So, my advice to you is; Hang on to your friends and family, and try to forgive them, when they annoy you. In the long run, it is best for yourself.
Hmm That is a hard advice to follow, but it does make sense. I will do my best. Thanks for your help.
You are welcome.
Hi You have called Bright moral animal hotline. How can I help you?
Hi My name is Pongo. I have a problem. It´s my joint and muscles that are aching. It hurts. Possibly because I have to carry my baby around all the time. Do you know what I can do about it?
Congratulation with your child. I hope everything is going well and that the kid is doing fine. Unfortunately, I am not a doctor.
Ooh I had hoped you could give me some advice.
Maybe I can help you. I guess you’re an orangutan. Which Island do you live on?
Right you are. I am an orangutan (Pongo pygmaeus) from Borneo.
Then I might be able to help you after all. You see, A scientist named Helen observed orangutans on Borneo, for a long time. A few times she saw a very peculiar behavior among female orangutans1). What the orangutan female did was to bite of the top of the leaves of the plant Dracaena cantleyi. This plant is not something, that orangutans otherwise touch or eat. The female orangutan would chew on the leaves for 3-5 minutes, until it became a green-white lather substance. This substance was then applied on joints and muscles. Like when humans apply sunscreen. As a matter a fact, the locale humans also use the plant the same way and for the same purpose. I don’t know who learned it from who.
Huhuhu -that is interesting. Do you know how it works?
Yes, I just read about it. This might be a bit complicated. The scientist made different extractions from the top of leaves of the Dracaena cantleyi plant 2). They tested the extracts on a human cell line, and found that some of the extracts reduced cytokine production, such as cytokine interleukin 6. Interleukin 6 is known to be involved in inflammation response. This means that there is a substance in the leaves, that reduces the amount of interleukin 6 produced. The substance acts as an anti-inflammatory substance and could reduce the pain in the muscles and joints.
Wauuwau – I got to try that. How do I get it?
My advice to you is:Be open about your health problem, and ask others how they handle this type of problem. This means, that I think you should ask around among your friends and hear if they have dealt with the same type of pain. I believe one of them might know, which plant to use.
Great idea – I will ask around, and with a bit of luck I will get rid of the pain. Thanks for your advice.
You are welcome.

Hi This is Bright moral animal hotline. What can I do for you?
Hi My name is Gastero blop blop. I have a small issue with my friends. I feel like they are always picky bagging on me.
What do you mean by that?
Well you see – I am okay smart, so I learn things reasonably quick, but I have to work for it - blop blop. My friends they are lazier than me, so they just copy what I do. I find that quite annoying.
Hmm I get your point, but maybe it is not as bad as you think. Let me tell you about a recent experiment on some sticklebacks. I assume you are a stickleback (Gasteroteus aculeatus) – right?
Right you are – I am a fish living in the water. So, what have you got?
See – the experiment was setup like this. Some researchers were working together with 3 groups of sticklebacks 1). One group was trained to follow a green-light in order to find food. A second group was trained how to swim into a box through a small hole to find food. The last group of sticklebacks was not trained at all. Then they mixed the groups. Trained fish joined up with untrained.
Interesting – why would they do that?
Well see – the mixed groups were then set in an aquarium, where they had to find food. To find the food they first had to follow the green-light, and then they would arrive at the box, which they had to enter in order to get the food. If the mixed group had sticklebacks trained in following the green light, then the group quickly found their way to the box area. If not, it took much longer time. Once the mixed group had found their way to the feed box, they had to enter it. If there were some in the group, who had been trained in getting into the box, then the group was fast to enter into the box with the food. Otherwise it took more time. So, if the untrained fish, were in a group with trained fish, they also found the food faster.
Yeah that is exactly what I mean. They don’t have to work for it – those lazy folks.
I get your point – but that is not the main learning from this experiment. The main thing is that the group, in which some fish were trained in following the green light and some were trained in entering the box, were by far the fastest group to find the food. The slowest were the group were none of the sticklebacks had been trained. The groups having either green-light-trained or feed-box-trained fish had an in-between timing.
Okay You got my point – what is your point?
Well my advice to you: Share your experience with others, and let them share their experience with you. That will solve your problems much faster.
I think I get the picture. It is better for me to pool experience with others, rather than worry about potential free-riders.
Great – thanks for your advice blop blop
Are you stressing your kid?
Hi This is Bright Moral Animal Hotline. What can I do for you?
This is Norve speaking – I am soon to become a rat mum and it makes me nervous.
I believe you – To become a parent can be quite stressing. But most mums work it out, and manage. You don’t need to worry.
Well my own Mum, who is to become Granny, is also stressed about my pregnancy.
May I ask – was your mum very stressed, when you were child?
Yes, indeed she was - My mum is the worrying type.
Hmm – have you heard about the double-hit hypothesis?
No, I can´t say that I have – What is that about?
Well, It says that if your ancestors have been stressed, and you also encounter stress, then you will be much more vulnerable, than others. Let me tell about a recent experiment that was made on Wistar rats 1). It is a bit cruel, but I hope you can handle it.
I will try not to get to emotional about it.
Great – well you see - some scientist took a lot of pregnant rats, and then they stressed the to-be mums by confining them in a small tube for 1 hour. Then they did the same with the next of generation of pregnant rat mums, and so forth, for four generations. The last generation was also stressed the same way, by confinement in a tube for 1 hour a day over 3 weeks. Some of these stressed rats were put together in pairs after the stress treatment, whereas others were to live alone.
This sounds awful.
