See text Alepocephaliformes is an order of marine deep-sea teleost fishes.

[2] It was previously classified as the suborder Alepocephaloidei of the order Argentiniformes.

[3][4][5] As an adaptation to a life in the deep-sea, there is no swim bladder, and the ossification of the skeleton is reduced.

[2] The largest known member is Narcetes shonanmaruae, the largest deep-sea-endemic bony fish.
