6. Anglerfish

A.k.a that creature Marlin and Dory come across when they were looking for the goggles in the dark in “Finding Nemo”. Super-sharp chompers and a light producing organ would be the defining points of this hideousness. As if they weren’t scary enough, they are also, puhretty weird, when it comes to reproducing. When the males age and mature, they lose their digestive system and then latch onto the females to keep themselves from starving to death.
