The two currently recognized extant species in this genus are: [5] Alepisaurus brevirostris Gibbs, 1960 (short-snouted lancetfish) Alepisaurus ferox R. T. Lowe, 1833 (long-snouted lancetfish) The anatomic difference between the two species is the shape of the snout, which is long and pointed in A. ferox, and slightly shorter in A. brevirostris.
Alepisaurus ferox, also known as 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). [ 3 ] [ 4 ] This species grows to 215 cm (85 in) in total length and a weight of 9 kg (20 lb).

Most oceanic species (78 per cent, or 44 per cent of all fish species), live near the shoreline. These coastal fish live on or above the relatively shallow continental shelf. Only 13 per cent of all fish species live in the open ocean, off the shelf. Of these, 1 per cent are epipelagic, 5 per cent are pelagic, and 7 per cent are deep water. [16]
Depending on the exact species involved, the maximum length of lancelets is typically 2.5 to 8 cm (1.0–3.1 in). [47] [48] Branchiostoma belcheri and B. lanceolatum are among the largest. [47] Except for the size, the species are very similar in general appearance, differing mainly in the number of myotomes and the pigmentation of their larvae ...
