Sabertooth fish

Sabertooth or sabretooth fish are small, fierce-looking deep-sea aulopiform fish comprising the family Evermannellidae. The family is small, with just eight species in three genera represented; they are distributed throughout tropical to subtropical waters of the Atlantic, Indian, and Pacific Oceans.

These fishes are named for their oversized, recurved palatine teeth, similar to those of saber-toothed cats (and the prehistoric Enchodus). The family is named Evermannellidae after Barton Warren Evermann, noted ichthyologist, naturalist and director of the California Academy of Sciences.
