California Moray Eel

Aquarium Inhabitant Bio

Gymnothorax mordax


A large snake-like fish. Can be identified by its long and slender body, mottled brown coloration, sharp teeth, and lack of fins or gills. The Moray in this tank is 2' and can often be seen among the rocks.

Habitat and distribution

Most commonly found on rocky reefs hidden in caves and crevices. Ranges from Southern California to central Baja.


Mainly fishes, but can opportunistically prey on cephalopods (eg. squid and octopus) and crustaceans (eg. shrimp and lobster).

Fun Fact

The California Moray possesses a second set of jaws, called "pharyngeal jaws" deep in its throat. These jaws have inward facing teeth to ensure that live prey items do not escape.
