Bald eagles don't sound like they do on TV. They dub over the call of a redtail hawk. Actual bald eagle calls sound more like a seagull. Similarly, lion roars on tv are usually dubbed over with tiger roars, because an actual lion roar is usually too deep to record well so it sounds weak, but apparently is terrifying IRL.

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.

A group if dolphins is a pod, a group of Falcons is a cast. When you watch the Miami Dolphins play the Atlanta Falcons you are watching a pod-cast on TV.

The nautilus has remained essentially unchanged for 400 million years. They just evolved to their current form and stayed that way. The first dinosaurs didn't even appear until 230 million years ago. If it ain't broke don't fix it.

Gorillas, along with other primates, can learn sign language to the point where even if they do not know a specific word for a specific object they can use their previous vocabulary to describe the word accurately. Like for example, Koko the gorilla never learned the word for "ring", so one day she pointed at a ring and signed the words; "finger-bracelet".

The airspeed velocity of an unladen swallow (European) is roughly 11m/s or 24 mph.

Crows will see how you look like and how you act and tell other crows about you.

Ravens can mimic sounds and speech like parrots can.

A bat's immune system is so strong it could withstand viruses that could be highly damaging to other species.

Most elephants weigh less than a blue whale's *tongue*.

When a male octopus is ready to mate it rip's off its ding dong and throws it at the female so she can do whatever she wants with it. the reason they do this is because they're a lot smaller than the female so she'll eat the male but on the plus side the Male octopus will grow his ding dong back eventually.

There is only two mammals left that lay eggs, and they are both from Australia.

Astronomer here! There are (probably) tardigrades on the moon. A few years ago an Israeli satellite accidentally crashed there that had tardigrades on board that likely spilled all over. The reason this is interesting is because these are really hearty little creatures that can survive really extreme temperatures and dehydrate into suspended animation. The company that crashed them almost definitely thinks the tardigrades are still alive. So hey, the moon probably has life on it now, and that happened while none of us were paying attention.

Unlike humans, dolphins must actively decide when to breathe. Captive dolphins have been known to hold their breath until they die of suffocation, which some have suggested amounts to dolphin self-harm.

Wombats have cubic poops. They literally s**t bricks!

Foxes use the earth's magnetic fields. "Like a guided missile, the fox harnesses the earth's magnetic field to hunt. Other animals, like birds, sharks, and turtles, have this "magnetic sense," but the fox is the first one we've discovered that uses it to catch prey. According to *New Scientist*, the fox can see the earth's magnetic field as a "ring of shadow" on its eyes that darkens as it heads towards magnetic north. When the shadow and the sound the prey is making line up, it's time to pounce.

There is a species of Zombie Worm called the Bone-Eating Snot Flower. Yes, zombie worms and bone-eating snot flowers are real animals.

A horses teeth takes up more space in their skull than their brain.

If you placed an adult blue whale length-wise on a basketball court, the game would be cancelled.

A snail can sleep for three years.

Humans over long distances can outrun all other land animals.

Giraffes chew on bones to give them extra calcium.

Sperm whales in the Caribbean have an accent.

One of my favorites is about cats! Did you know that they have UV vision? That means that when cats play with random paper balls, bags, spots on the wall, or the box their toy came in, they're actually playing with the ingredients that are UV reactant (like glues and stuff)

Turtles can breath through their butts. And Owls keep little snakes as pets.

There is an extinct species of bee that we only know exists because there is an orchid whose naughty parts mimic the bee in order to trick them into pollinating it!

When a specific species of carpenter ant (Colobopsis saundersi) realizes it's going to lose the fight it's having with another insect, it latches onto them and then *blows itself up.* Membranes along the ant's body can be activated that'll lead to combustion. Special enlarged glands in its head mean the explosion sends a glue-like substance shooting out that will very likely entrap the previously presumptive brawl victor.

In clownfish, each 'school'( tribe whatever) has one female, and a head male and the others ( all males) , if the female dies, the head male turns into a female.. And the next in line to the ( leadership throne?) would be the male leader and bang the former male leader. Yeah clownfish are Wacky.

Polar bears fur is actually clear.

Caterpillars have over 200 muscles in just their head.

There's an intelligent species of jumping spider called as the "Portia Spider". These little munchkins are specialized spider hunters, with different tactics for a particular problem. Their favorite food is the common weaving spiders. Their tactics ranges from imitating a fallen debris on the prey's web to directly attacking the prey. Their venoms are potent against spiders as it will only take seconds to paralyze the prey.

Sloths sometimes grab their own arms, thinking they're branches, and thus fall to their death.
