Many on the list of crazy animal adaptations have outrageous tools to hide from predators. Cuttlefish and leaf bugs, for instance, are absolutely unparalleled when it comes to camouflage and mimicry, while many young white-tailed deer essentially pretend to die in order to dissuade hungry killers. Others go a bit more extreme to piss off their enemies, such as Northern Fulmars, who vomit a disgusting liquid, and Pistol Shrimp, whose claw snaps and ignites a collapsing bubble of epic proportions. Other wacky adaptations found in animals range from the mere existence of an electric eel, as well as hooded seals who inflate a pink balloon from their noses to attract a mate.
Horned Lizards Autohaemorrhage
When you're starting to attack one of these Texan lone stars, don't be surprised if it shoots out a stream of blood from its eyes. Even if its in the mouth of a fox, the autohaemorrhage adaptation is so disgusting, the fox will drop the lizard because of the bad taste and trauma.
Some Jellyfish Are Immortal
If you go to the Mediterranean, check out the rare "immortal jellyfish," which has evolved in ways that make us question reality. These little jellyfish start as sexually immature animals, reach sexual maturity, and then have the distinct capability to indefinitely revert itself back into that sexually immature stage all over again.
Pistol Shrimp Will Shoot You
With an adaptation of this proportion, do not order a pistol shrimp cocktail appetizer anytime soon. When this type of shellfish snaps its extremely unique claw, the sound scares the crap of every living thing in its path, and it also shoots off a collapsing bubble that stuns the victim.
Basilisk Lizards Might Be the Second Coming
Basilisk lizards walk on water, which is why they've garnered the lovely nickname "Jesus Lizards." This adaptation comes in handy when fleeing from mammals and reptiles who don't happen to have magical biblical powers.
