Anglerfish
Anglerfish just look mean. There are more than 200 species of them, and they live in the depths of the Atlantic and Antarctic oceans, although they can also be found in shallow, tropical environments sometimes.
They have giant heads and huge mouths filled with sharp, translucent teeth, but their most notable feature is the piece of their spine that hangs over their mouths like a fishing pole. It lights up to lure in its victims.
