Wikipedia Abstract

Alepisaurus ferox, the long snouted lancetfish, longnose lancetfish, or cannibal fish, is a species of lancetfish found in the ocean depths down to 1,830 m (6,000 ft). This species grows to 215 cm (85 in) in total length and a weight of 9 kg (20 lb). They are sometimes taken as by-catch in tuna long-line fisheries, but are not a targeted species. It is often called the cannibal fish because numerous individuals have been caught after having devoured other lancetfish.
