Longfin African conger

The Longfin African Conger (Conger cinereus) is an eel of the family Congridae known by several common names, including the blacklip conger, moustache conger, and ashen conger. Its range covers much of the Indo-West Pacific, from the Red Sea and East Africa, to the Marquesas and Easter Islands. It is generally found in shallow coastal and reef habitats, and is known for its nocturnal, often reclusive behavior. The population found in Hawai'i was originally classified as a subspecies (C. cinereus marginatus), but was later considered its own species (Conger marginatus).
