10. Anglerfish
Ah yes, one of the most famous species down below in the sea that give us nightmares, with the luminous organ on the top of its head that lures unsuspecting prey into it’s mouth, filled with long fang-like teeth. Anglerfish can grow as long as 3 feet long and as small as 8 to 9 inches. We’re just relieved we don’t see any of these up on the surface, right?
