On the surface level, we understand that animals, insects and marine wildlife are, physically, quite different from us. But once you start to look more closely at their behavior and biology, there is a whole world of interesting and unusual parts most of us had no idea about.
Someone asked “What’s a fascinating fact about wildlife that most people are unaware of?” and people shared their best examples.

There are reports of elephants finding humans sleeping under trees and the elephants think they’re dead. People have woken up with elephants gently stroking them with their trunk and in some cases they try to cover them with branches and sticks as a “burial”
Elephants are one of the few animals who mourn their dead and have rituals.
Vultures are really important for the ecosystems they live in, but a lot of vulture species are critically endangered due to human activity. Vultures have stomach acid so powerful that it can destroy things like botulism and anthrax, thus cleaning up the environment when they eat rotting meat that contains those things. There is evidence for a correlation between the drastic decline in India’s vulture population and the boom in the stray dog population, since less vultures means there is more food for the dogs to scavenge. This has also sadly led to a rise in rabies which kills many people and animals. Many people find vultures scary, but for the most part they are harmless and we really need to have them around. Please consider supporting vulture conservation projects.

Owls bob their heads up and down to help improve their depth of perception.
You can try it out yourself. Focus on an object and bob your head. It doesn’t work for us, but you do look like an idiot.

Raccoons have the most soft, velvety, devilish little hands.
Baby raccoons purr and knead like kittens. Did not know this myself until last spring when a wildlife rehabber posted a call to arms for people to help. (Figured I’ve raised enough neonatal kittens, my experience would be helpful.)
A ban has been lifted in my state and people are poisoning adult raccoons without considering the babies they are orphaning. Last year I raised and released 11. So far this year I’ve raised and released 27. I’ve also officially become a wildlife rehabber. One of the females I raised last year showed back up, babies in tow! Wasn’t sure how she’d respond after being away for a bit but she let me check her out and treat her battle wounds.

Elephants have a specific warning call that means “human.”.
#6
Manatees control their buoyancy by farting.
#7
You can’t cull coyote populations. Through howling they know how many are in their pack and if the number drops the females will respond by having larger litters. Killing coyotes just creates more coyotes.
#8
Crows can mimic human voices similar to parrots. I experienced that first hand while hunting on public land. Heard a little boy calling “MOM” “MOM!!” only to realize that the voice came from a crow flying overhead.
#9
I’ve told this one before, but some bar-tailed godwits (a wading bird) fly from Alaska to Australia non-stop in the longest continuous migration of any bird (maybe any creature).
To do this, they shrink their internal organs so they can pack more fat (for energy) into their body. They’re basically balls of fat when they take off. And when they’re in flight, they shut most of their organs down to devote all energy to flying.
And they’re just medium sized nondescript brown birds that peck around in the mud. I love wading birds, man.
#10
Young goats pick up accents from each other, joining humans, bats, and whales as mammals known to adjust their vocal sounds to fit into a new social group.
#11
If you put a hamster wheel in the middle of the forest, you’d expect that small creatures would ignore it. They don’t. Instead, they absolutely love it! Scientists believe it’s because it provides some kind of novel stimulation that hits the core of most animal brains!
#12
Every single whiptail lizards is female. They reproduce by parthenogenesis, a natural form of asexual reproduction.
#13
Caribou & Reindeer are the same species. Their ankles make a clicking sound when walking. It helps the herd follow each other in snowstorms. My knees make clicking sounds…but that’s just lack of cartilage😕.
#14
There is a type of mouse that behaves like a tiny wolf. Members of this species travel in packs, hunt live prey, and even howl. It is called the Grasshopper Mouse, named for one of its primary food sources.
#15
Opossums brains are about 1/5th the size of other mammals their size. And mostly smooth, so precious and so dumb.
Eponarose:
Amazing Opossum Fact 1: It is extremely rare for them to have rabies!
Amazing Opossum Fact 2: They were used in the development of anti-venom!
#16
My favourite fact ever: penguins have knees. Will never not baffle me. Knees.
#17
There are coyotes in every major city in the USA. If you’re in the US, you’re likely less than 1mi away from one.
Edit: contiguous USA.
#18
Flamingos are not naturally pink. They are born grey. But their feathers turn pink because of their diet of shrimp and algae.
IntelligentHippo4245:
To add on to Flamingos, they can lose their color when raising their babies because it’s so intense of an experience.
#19
When a hornet invades a beehive, the bees will swarm it, and raise the heat of their bodies burning the invader to death. This ends with perhaps dozens of the hive’s protectors dead, but is seen as worth it to protect the hive and it’s inhabitants.
#20
An opossum’s body temperature is too low for rabies to survive in it. They also kill most ticks that try to latch on.
#21
Penguins mate for life. The male penguins scour the shores for a beautiful stone and then proposes. If the female accepts, they mate for life. Also, the female goes to hunt after the egg is laid while the male watches/sits on eggs.
#22
Ants have disinfectant saliva, and some actually treat the wounds of their fellow ants.
#23
Male platypus have venomous spines on their back feet, one on each side. The pain has been described as unbearably excruciating and can last for months on end. Platypus may look very cute, but never ever pick one up unless you are a trained wildlife carer.
#24
One fascinating fact about wildlife that often surprises people is that some species of octopuses are known to use tools. They’ve been observed collecting coconut shell halves and using them as portable shelters.
#25
Orcas are predators of moose. Moose can swim (and dive quite deep) and orcas have been seen attacking and killing moose in the wild. It’s not a common, everyday occurrence. But I think it’s metal as f**k.
#26
Wild wolves are pretty timid around humans and getting attacked by one is so extremely rare.
#27
A flamingo’s head has to be upside down when it eats. This is interesting to know!
#28
Fungi can help build "wood wide webs" connecting surrounding tree roots in the forest. These "webs" are used as warning systems when a tree is in distress from an attacker and these systems also transfer nutrients and other goods to eachother within the system.
#29
The Mayfly’s adult lifespan is so short they are born without a mouth.
#30
Scientists studying sperm whales are ignored/shunned if they wear scuba gear. If they use drones, like submersible ones, the whales leave. If they free dive, no gear, holding their breath about 10-15 feet deep, for a few minutes at a time…
Whales approach within feet of the diver. Close enough a full strength hunting “call” would pulp the human. Close enough the energy from a normal “scan” heats up the divers.
Sometimes, the pod will surround the diver, floating vertically, and swap over to their communication mode.
As James Nestor (look him up on Youtube) says – Getting that close to an animal that can kill you with its voice, when there is a chance that specific whale may be old enough to remember being hunted by humans… is pretty sketchy.
#31
Rats have collapsible ribcages – it’s why they can fit through such small crevices.
#32
Deer will eat human remains. It’s known that they are very occasional opportunistic carrion consumers, and this has included film of a deer munching on human remains at a body farm. I guess there’s no reason to assume that carrion wouldn’t include human remains, but it’s just sort of a weird thought, we just don’t think of deer like that.
#33
Bull Sharks can survive in any kind of water. They swim into rivers to have their young because there are fewer predators, hence you hear news stories about sharks in the Mississippi River.
They are also a******s and will bite with very little provocation. IIRC they cause more “attacks” than Great Whites but they’re nowhere near as big so they don’t do as much damage. They are still the 3rd most dangerous shark in the world behind Tigers and Great Whites.
#34
Some species of birds can sleep while flying, known as “unihemispheric slow-wave sleep,” keeping one hemisphere of their brain awake.
#35
Elephants can’t jump.
#36
Squid brains are donut-shaped and the digestive tract goes through the hole in the middle.
#37
Buffalo/ American bison only have one lung cavity. They have 2 lungs, but they are together in the same cavity. It’s what makes such incredibly powerful dumptrucks of pure muscle so vulnerable to a single gunshot, or bow shot.
#38
Sharks can “smell” electricity.
They have pores on their snout that can detect electrical fields, and they use this sixth sense to hunt. They are capable of sensing the electrical currents a brain uses to communicate with muscles, and have even been known to chew on underwater electrical cables. It’s possible that they can even tell if a creature is feeling calm or panicked this way.

Whale milk is the same consistency as toothpaste.
#40
Pigeons produce milk.
