Ladybugs are cannibals
These brightly coloured beetles aren’t afraid to turn on each other when food is scarce. If it’s a matter of survival, adult ladybugs will eat other freshly moulted or newborn ladybugs. The beetles also have a wicked defence mechanism: When startled, ladybugs emit a foul-smelling fluid from their leg joints that helps scare away predators.
Starfish have ghoulish eating habits
It may come as little surprise that these unusual creatures have a few biological eccentricities – they see through tiny “eyespots” at the tip of each arm, for example. But their eating habits qualify as downright grotesque. To consume a mussel or clam, the five-pointed critter pries the shell open slightly, ejects its stomach from its mouth into the shell, digests the animal, then slides its stomach back into its own body.
Snails have razor-sharp teeth
How terrifying can an animal really be if it moves at an average speed of 0.048 kph and leaves behind a trail of goo? One look into a snail’s mouth will tell you: Gastropods, including snails and slugs, have thousands of tiny teeth located on a ribbon-like structure called a radula. Depending on the species, they use these teeth as a poison harpoon, to cut prey, or, in the case of the ghost slug, to seize and devour earthworms.
