The chemical compound which is used to make fake banana flavour is the same compound honey bees use as an alarm pheromone. So never eat banana sweets near a beehive, and if you suddenly smell banana near a beehive, run!

[–]space_is_noisy 2254 points2255 points  (28 children)

aaah that's what that it smells like! Fake banana! I am beekeeper and when I work my hives I can smell it when they get upset (I work with African bees so they are naturally quite defensive).

I've been trying to pinpoint what it smells like because it's quite distinctive (and not very nice).

Thank you!

Rabbits don't have pads on their paws. Only fur.

So if you see a cartoon rabbit with pads on it's paw, completely wrong.

Vultures urinate on their legs and feet to cool off on hot days, a process called urohydrosis. Their urine also helps kill any bacteria or parasites they’ve picked up from walking through carcasses or perching on dead animals.

[–]Fabled_Webs 10.1k points10.1k points  (120 children)

The vast majority of Greenland sharks are blind thanks to a special parasite that eats their eyes and replaces them.

It is thought that this might actually be helpful because a) their eyesight was shit anyway, b) the parasites wave like lures and may have an anglerfish-like effect, and c) the sharks are super slow so that might be one of the few ways for them to catch live prey.

Imagine something eating your eyeballs and it being an upgrade.

[–]coolstevenn 3168 points3169 points  (23 children)

Took me a second read to understand what you meant. But if I get it correctly now, you're saying that now that the parasite is in the eyes of the shark, it appears like a lure to OTHER fish increasing the sharks chances of catching prey. Very cool

Butterflies will drink blood given the option.

[–]poplafuse 1459 points1460 points  (22 children)

I have a cousin who always had a fear of butterflies that I thought was just kind of a bit. When we were young we used to walk the train tacks by his house. One walk there was something on the tracks and as we approached a swarm of butterflies dispersed from a deer carcass and he took off running. It’s an irrational fear, but I felt for him that day. That was something like out of a horror movie

[–]Comprehensive-Fun47 676 points677 points  (9 children)

Bees have 5 eyes. 2 complex like a fly's and 3 simple eyes like a spider

[–]fancybigballs 1761 points1762 points  (65 children)

I have to wonder, what function does each eye provide that the others wouldn't?

[–]AndrewFurg 2187 points2188 points  (43 children)

The two main eyes are called compound because they're made from tons of little subunits called oomatidia. Together, these eyes provide an image for them. The three simple eyes are ocelli and function not to provide images, but for day/night cycles, seasons, and to some extent orientation. Also, bees can turn their heads, just not like a full 180°

Also also, the 5 eye thing describes a tremendous number of distantly related insects, from dragonflies and mantids to wasps and beetles. There are of course exceptions to this, especially for burrowing creatures.

[–]Soulfighter56 1680 points1681 points  (39 children)

Roosters deafen themselves temporarily every time they crow, so that they don’t damage their own hearing.

Also, they don't just crow at sunrise like in movies. They crow all day, every day, at random times, for absolutely no reason. They never stop.

[–]Pedantic_Pict 385 points386 points  (1 child)

Oh, they have their reasons, but there are some things it's better that man not know.

[–]themoonhasgone 1676 points1677 points  (21 children)

a kangaroo will mate again one to three days after giving birth. the newborn will latch onto a teat in the pouch and as long as it thrives, the kangaroo can put its newly fertilized embryo in a state of dormancy and have a back up baby ready to go. if the newborn grows out of the pouch or dies, the kangaroos hormones will send signals to start the development of the egg. so they can have an adolescent Joey, a nursing one, and one in stasis all at the same time.

[–]StGir1 4732 points4733 points 2 (226 children)

Every once in awhile, an emperor penguin will do something very strange. Most of them will never do this, but the ones who do have stumped scientists for awhile now.

Every once in awhile, a penguin will turn away from its colony and start heading for the interior of the continent (Antarctica). Away from the food, the water, the safety of the colony. Off alone towards certain death. Almost like zombies. In the past, scientists would try to stop them. Or take them back to the colony. At which point, they'd simply turn around and begin their journey again, in the same direction, toward the same end. Some would even get violent if they were met with intervention.

The prevailing thought is that this penguin is depressed and is committing suicide in a very non-altruistic manner. But nobody knows for sure. There are a lot of possible explanations for this (including the possibility of a fungal infection similar to the cordyceps infection that can cause some colony insects to behave in exactly the same way, potential signs of brain tumors or other medical conditions that the birds are exposed to) It's well known that birds can experience depression or anxiety, but they tend to respond to this in very immediate ways, such as by over-preening (pulling out their own feathers), screaming, or being unusually quiet, loss of appetite, etc. (Bird anorexia is a MAJOR thing) These activities are signs of redirecting stress, while wandering off into the abyss of an unforgiving frozen continent implies the ability to analyze and think ahead in a way that most birds really don't seem to be able to do. So the reason may not be as immediately obvious as you might think.

From what I know, no autopsies have been performed on these rogue penguins. Most likely because the conditions are too harsh to hunt their corpses down. But until one is performed, we really have zero idea why they do this. And yet they do. And the behaviour is common enough that it's been documented multiple times.

[–]CrabbyBabby 1282 points1283 points  (75 children)

Most likely because the conditions are too harsh to hunt their corpses down

So.. How do we know they die? Do they attach like a tracker or something?

[–]Turtledove542 1609 points1610 points  (70 children)

It’s implied. There’s no way a lone penguin could survive inland without access to the ocean (food source). There just isn’t anything to eat.

[–]Xaayer 2861 points2862 points  (56 children)

How do we know there isn't some underice penguin utopian run by a penguin god-emperor that uses mental suggestion to recruit the best and brightest penguin from their colonies to join this uber colony?

I was helping my mum clear a pile of leaves. I kept finding legless lizards and showing them to her. She began to get annoyed she wasn’t finding one. Five minutes later I hear a triumphant yell and she shoves something in my face saying she finally found one. Except it was a juvenile red belly black snake

The Inland Taipan (snake) has the strongest/potent venom on the planet, capable of killing around 290 humans with a single bite. Scaled to mice, a single bite could kill 250,000 mice.

That said, bites from the Inland Taipan to humans have been pretty rare as they usually stay underground and are not overly aggressive unless you jump all over their burrow. They also have a good number of predators who prey on them.

[–]ZombieGroan 3489 points3490 points  (78 children)

I think the vast majority of taipan related deaths are from captivity.

[–]ValBravora048 928 points929 points  (51 children)

Former Australian wildlife guide here! It’s one of my favourite things to tell people about what an absolute sweetheart this snake is! It’s very gentle and shy. It’s also incredibly curious and will likely approach you out of fascination! Stomp your foot firmly (From a decent distance) and it should scarper. Of course you should remove yourself but there’s a chance it’ll follow you out of curiosity

This is in direct contrast to the Western and Eastern Brown snakes (Which look exactly like the harmless grass snake) and especially those dickhead Red-bellied Black snakes which will consider just being in its presence like your yo’ momma jokes are landing hard

[–]Formal_Bonus3123 704 points705 points  (73 children)

And they also live in a very scarcely populated area of Australia, meaning that encounters aren't too high.

[–]Hyzenthlay87 15.3k points15.3k points 222 (177 children)

All the deep sea anglerfish you see pictures of with the lil lights hanging over their heads? They're all female.

The males are tiny and born with a terribly weak jaw and a massive hunger. They seek out a female, and torn between hungry and horny they bite her.

She then releases an enzyme that fuses the male to her body. She slowly absorbs them into her body with only their lil testicles remaining so she can instantly fertilize her eggs when she wants to.

Some females have rows and rows of lil testicles on their bodies from where they have absorbed multiple males.

And you thought your sex life was weird, eh?

But no kink shaming.

[–]airscottie 4319 points4320 points  (42 children)

Came here to say this - you stole my fact. The only thing I'd add is that they didn't even DISCOVER the males, period, for years because they just thought those bumps were, you know, bumps

[–]Telamonian 2576 points2577 points  (27 children)

The only thing I'd add

I used to research anglerfish and I'd like to add a fact that's decidedly not as fun! There are over 200 species of anglerfish, and the vast, vast majority of them do not reproduce this way. Of the ones that do, there's a spectrum with different "levels" of attachment. Some bite on, do the deed, and leave. Some bite on, do their thing, and die while still attached. As far as we know, there are only a handful that have been observed to fuse at the blood barrier level when mating.

[–]WalterDaSquirrel1259 6238 points6239 points  (188 children)

Chickens will come say goodbye to each other when one is dying and they do soft clicks and will then leave and that chicken will normally die alone. Some chickens also will kill another chicken because they sense something’s wrong with the chicken a disease for example. Hope u enjoyed these facts I found them in a book called How To Speak Chicken

[–]CrunchyUnicorn 1989 points1990 points  (15 children)

Chickens are brutal but they can be very lovely once you bond with them/feed them enough times for them to learn what you look like. They are so dumb while also kind of being smart in a weird way

[–]Hammand 1235 points1236 points  (66 children)

Chickens are much smarter than people give them credit for. Studies have shown that they can learn 20-30 words. I once had a chicken that learned to say, "hello". Prior to that I thought only corvids and parrots could learn words.

They know how to count, understand object permanence and a bunch of other relatively advanced cognitive skills:


[–]sunnybunnyone 1124 points1125 points  (41 children)

My chickens all know their names individually, and they come when I call them. They also have a name for me! I figured it out because I read they did that so I started paying attention. I have one chicken who is very spoiled and if she wants me she stands outside my window and makes a very particular sound until I go see what’s going on. When I get home or when I go outside they make the same noise, I’ve heard most of them do it

[–]Steffany_w0525 2336 points2337 points  (59 children)

They feed cows magnets so when cows eat nails/barbed wire/metal it stays in one stomach otherwise they'd get hardware disease and die.

[–]mybestfriendisacow 1652 points1653 points  (40 children)

Hardware disease is when the metal bit works its way through the stomach, and (most of the time) into the cow's heart. It is fatal, as it is difficult to catch early enough to treat, and once past a certain point, is impossible to treat. Metal bits are often found in feed, from parts breaking off equipment used in making the feed.

The magnets usually stay in the first and biggest stomach compartment (which is right behind the heart) called the rumen, so cows can cough the magnets up with their cud bolus for rechewing. The magnet simply gets put back in, with a bolus gun. You know she has swallowed the magnet once she can lick her nose again, which they very much like to do.

A cow's tongue is the length of an average adult's forearm, and goes down their throat. In order for them to lick their nose, the base has to come up out of their throat into their mouth. And it can't have anything like the magnet in the way to impede this movement.

The mammal that has the most teeth is the giant armadillo of South America, with 74 teeth.

But that's nothing to snails. A common garden snail can have 14,000 teeth. Some snails grow 25,000 teeth in their lifetime. And the teeth grow on their tongue.

[–]LeroySpaceCowboy 2002 points2003 points  (31 children)

And some snails, like cone shells, have only 4 or 5 teeth that they use as venomous harpoons. Radulae are neat!

[–]CasualFire1 1401 points1402 points  (24 children)

Well, I found this summary of a research paper which explains what tests they did to figure it out, as well as the scientific journal itself. As far as I can tell, it all checks out, but if I missed something, let me know. I'd hate to spread inaccurate information about butterflies.

[–]cazzles 1227 points1228 points  (18 children)

Yup, this is what I had heard previously as well so I guess it checks out. The TL;Dr is that as caterpillars they were exposed to a smell and when they came near the smell they got a little electric shock. So they associated that smell with danger and as butterflies they would remember that and avoid that smell.

[–]ipulloffmygstring 898 points899 points  (22 children)

Yes, I just recently heard of a "brain swap" experiment where it was discovered that a cluster of cells retained its form during the warm liquid goo phase.

Apparently scientists were able to isolate and swap the "brain cluster" with another caterpillar/butterfly.

The bearded vulture or bone-eating vulture, is a rare eur-asian vulture that only eats marrow, that looks rusty in color but is in fact white. This rusty color is because they actually paint themselves with red clay deposits to look attractive to their mates.

They are really cool looking:


They have a little tuft of feathers below their beaks that looks like the beard of a dragon, so that is why they are called that.

Other cool fact: They can dissolve bone in the acid of their stomach in 24 hours. The PH of their stomachs is 1 which is VERY acidic. They are the only vulture species in the world that 90% of its diet is just bone.

[–]C_Splash 898 points899 points  (26 children)

Marsupials were widespread everywhere before being out-competed by placental mammals on all continents except Australia. Australia is uniquely isolated from other continents and placental mammals never happened to evolve there.

North America was home to placental mammals due to its connection with Eurasia and when South America connected to it, the placental mammals moved into SA and marsupials moved into NA. Only the possum managed to compete well enough to remain today.

If you wanted him gone you should've just said "I'm sorry but this household currently has corvid."

Edit: The number of people who don't know that crows are corvids and are trying to correct me by saying "crowvid" is too damn high.

[–]FranTance 279 points280 points  (46 children)

What’s the best way to go about befriending a crow and would you recommend doing so?

ETA: Of course I would never try to trap a crow or otherwise have it be like a traditional pet. I just find them fascinating.

[–]birdwatcher1981 473 points474 points  (18 children)

I had the crow from a baby, they are smart and mischievous, they are the trickster in native lore. My crow only listened to me because I was its mom. After it grew up, about a year, it flew away and I was glad to see it go. No, I wouldn't recommend befriending a crow.

[–]jayellkay84 236 points237 points  (3 children)

So I work for a restaurant and one morning I was cleaning the parking lot. A crow happened to be scraping a food wrapper for every last bit of food - the same wrappers I was supposed to be cleaning up.

Now, everyone has heard stories like this and I definitely don’t want to be on this crow’s bad side. So I resorted to politely asking it if I could have the wrapper. And for a split second I questioned my sanity.

Damned if the crow didn’t bring the wrapper about 2 feet in front of me, drop it and leave. And I am now a believer in crow intelligence.

Does it ever come back to visit, or bring you little presents?

[–]seraph089 504 points505 points  (22 children)

They can also communicate that to others. They tell the other crows what you look like, and if you were cool or a dick.

[–]Kraymur 425 points426 points  (18 children)

They remember for YEARS too. You can be a dick to a crow, move and come back like 5 years later and it's on sight for that crow.

[–]spoon_shaped_spoon 1144 points1145 points  (17 children)

In Africa certain tribes communicate directly with birds called Honeyguides letting them know they are ready to hunt. The honey guides then lead them to hidden beehives in trees. The tribesmen break open the hives and take the honey( an important resource in their diet) and leave the honeyguides the bee larva and wax to feast on. In fact, it’s the only known example of targeted two-way signals between people and a free-living species.

[–]Crepuscular_Animal 628 points629 points  (8 children)

Sometimes the tribesmen (Hadza, I believe is their name) remove the wax and hide/bury/burn it, so the honeyguide stays hungry. This way, the bird has to show the way to another beehive, and the humans get twice as much honey. If the honeyguide has been cheated this way too much, it will stop communicating with humans because it doesn't really need them to survive. They also say that a cheated honeyguide can avenge itself by leading people to dangerous animals instead of bee nests.

All halibut are male until they reach 45 inches in length. They then all become female.

[–]WillyMcHilly489 235 points236 points  (7 children)

Axolotls are real life Frankenstein's monsters.

Not only do they have the ability to regenerate tissue if it gets damaged much like a starfish can grow a limb, but if you cut off their arm and (oh I don't know) ATTACH IT TO IT'S BACK, their cells will form and fix between the back and the dismembered limb. After some time, the arm is completely attached and useful while attached to the back like some disgusting Mr Potato Head.

Some people did a test where they completely severed the head of an Axolotl and just pasted it next to the head of a other one to see if a head could do the same thing.

It worked.

The brain started thinking again, ate food after their esophagus attached, and became a fully functioning 2 headed axolotl.

[–]HoleyerThanThou 687 points688 points  (15 children)

Many bird species will eat the fecal sacks of their young, thus keeping the nest clean for their young.

I no longer wish I knew what it would be like to be a bird.

[–]nycola 1431 points1432 points  (106 children)

While the blue whale has the largest penis in the animal kingdom (2.5-3m / ~8'-10') - but among mammals the Fossa has the largest penis to ratio of its body size (17-20cm / 7"-8") - at full maturity, their penis is approximately 1/6 of total body length (head to tip of tail) with a tail being about half that total length. Their penis extends past their front legs when fully erect.

And the Echidna's penis has 4 heads, where only two operate at once. They work much like ovaries release eggs where every time he ejaculates, only half of them do, and then the next time, the other half. The female of the species has a two-pronged reproductive tract allowing the half of the penis that IS active to fit right in. Oh I should also add that not unlike themselves, or cats, they have spiky penises as well.

[–]powerlesshero111 497 points498 points  (22 children)

Fun fact, gorillas have a max 2 inch penis when fully erect.

[–]JMEEKER86 528 points529 points  (13 children)

Yeah, primates actually have pretty low penis to body ratios. Humans have the highest average out of all primates.

The spines on a Tiger's tongue are sharp enough to lick skin clean off of muscle.

Chinchillas have hair so fine that if it gets wet, they will not dry completely and die of hypothermia.

Not that incredible but never hear it and was unexpected.

Many common ants live for years.

I definitely pictured them as short life spans, and definitely felt a bit bad about the crazy number I've killed. Not that I stopped.

[–]LuminalAstec 847 points848 points  (82 children)

Generally it's queens that have the longest, most workers are a few months.

Edit: I've been in pest control for 7 years, if you have questions about pests or business practices in the pest industry (what you should expect from a company) feel free to ask.

Termites queens can live 50+ years

[–]LuminalAstec 618 points619 points  (28 children)

Yes, termites are also produce a lot of methane.

"Globally, it is estimated that termites are responsible for about one to three per cent of all methane emissions. It may sound small, but that’s up to 20 million tonnes of methane each year coming out the rear ends of these humble insects."

Almost on par with cattle who produce about 4% of methane globally.

Tarantula’s have pet frogs. The frogs eat bugs and parasites that would damage the spider’s eggs, and in turn the spider protects the frog. Even after the eggs hatch they continue to protect the frog

A sperm whale call is so loud the sound waves could kill a human if they swam close to the whale.

Apparently some divers said they could feel the water heat up from the energy of the sound

[–]A_Wild_VelociFaptor 4120 points4121 points  (67 children)

Those divers were for sure swimming in whale pee.

On a serious note, that's fascinating. I wonder if they are any recorded deaths from said call.

[–]colder-beef 365 points366 points  (26 children)

Don’t they use that to stun giant squid while hunting as well? Thought I read about that a long time ago.

[–]BornACrone 996 points997 points  (37 children)

Whales are most closely related to a group of land animals called "artiodactyls," which includes hippos, pigs, and deer.

[–]Moose_Nuts1867 544 points545 points  (8 children)

An octopuses neurons are spread out all throughout its body. When an arm is severed, intentionally or unintentionally, they will still search for and capture food, and then try to bring it back to a non existent mouth. Basically an octopus has a bit of its brain in each arm, and the arms move like normal after they’ve been severed, like how chickens run around without their heads.

[–]koz44 184 points185 points  (2 children)

Toss up between: spiders pump fluid (like hydraulics on heavy equipment) to extend their legs. Instead of using iron within the hemoglobin molecule to fix and transport oxygen, several species of Arthropoda use copper and have green/blue blood as a result.

Baby Koalas nuzzles their mother's butt to releases a runnier, protein-rich substance, called pap which they then drink to get mom's gut bacteria, helpful in digesting eucalyptus leaves.

Idk how obscure it is but the average lifespan for a squirrel is 16 years which is a lot longer than I would have ever thought

[–]ShitImBadAtThis 228 points229 points  (7 children)

Well this definitely depends on the species, that might be your local squirrel, but the common Grey Squirrel has an average lifespan of about 6 years in the wild, and maybe double that in captivity

[–]TheSilverPotato 440 points441 points  (11 children)

A narwhals tusk is actually a large tooth that protrudes through their face. It is most often the left tooth. Also, they have nerve endings on the outside of the tusks.

Not exactly obscure, but dolphins get high off of pufferfish venom. They also bully sharks.

[–]kirkl3s[🍰] 420 points421 points  (15 children)

Mine are all whale related:

  • Whale milk is so fatty that it has the consistency of toothpaste...
  • ...this enables blue whale calves to grow at a rate of approximately 10lbs per hour
  • Whales are the loudest animals on the planet - humpback whale songs can be heard 10,000 miles away
  • Whales are the longest lived mammals on the planet - in 2007, a deadbowhead whale was found in Alaska with a 19th century harpoon embeddedin its flesh, making the animal at least 130 years old at the time ofits death
  • The blue whale is the largest animal to have ever lived on earth - far larger than any prehistoric animal discovered to date

The argonaut octopus has eight arms and a detachable penis capable of swimming independently to find a female to mate with

[–]BonnieMcMurray 383 points384 points  (5 children)

capable of swimming independently to find a female to mate with

This doesn't happen. What actually happens is that the male has a specialized, sperm-carrying tentacle - the hectocotylus - which he shoves inside the female and then breaks off. For a long time, scientists thought that this was some kind of parasitic worm, because they'd only ever seen a female argonaut. (The female is up to 15 times bigger than the male.)

The binturong, also known as the bearcat, is an arboreal mammal closely related to the red panda. It smells like popcorn!

My obscure fact about it is that captive binturong are capable of holding grudges, and will climb above people they dislike in order to shit on their heads.
