Sharks have no real tongue — just a small slab of cartilage, the basihyal, on the mouth floor. Useless in most species, it is the cookiecutter shark's key weapon: the shark latches on, retracts its mobile basihyal to create a vacuum, then twists out a round plug of flesh.

Sloths risk their lives weekly climbing down to poop — because of moths. Moths lay eggs in sloth dung, then return to live in sloth fur. Their activity grows green algae on the fur, which sloths eat. Their own body becomes a snack farm.
