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.

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 ...
