Alepocephali
Alepocephaliformes
Order of ray-finned fishes
Alepocephaliformes is an order of marine deep-sea teleost fishes.[1] It was previously classified as the suborder Alepocephaloidei of the order Argentiniformes.[2][3][4]
As an adaptation to a life in the deep-sea, there is no swim bladder, and the ossification of the skeleton is reduced.[1] The largest known member is Narcetes shonanmaruae.[5]
