This grotesque creature might look ferocious, but don’t worry, it can only grow to a length of eight inches.

Like many deep sea fish, the angler lures its prey by giving off light, which other fish (ironically) mistake for small animals that they can eat. The angler has a long, light-emitting dorsal spine which it waves through the water to attract a meal. When a fish gets close enough, the angler quickly turns around and chomps down on its prey.

Cool Fact: In some species of anglerfish, males are tiny, and can’t digest food on their own! How do they survive? They latch onto female anglerfish, and his body literally becomes attached to hers! They live as parasites, and their only function is to fertilize the female’s eggs.
