Saccopharyngiformes is an order of unusual ray-finned fish superficially similar to eels, but with many internal differences. Most of the fish in this order are deep-sea types known from only a handful of specimens. Scientific classification or biological classification refers to how biologists group and categorize extinct and living species of organisms. ... Orders See text The Actinopterygii are the ray-finned fish. ... Families Suborder Anguilloidei Anguillidae (freshwater eels) Heterenchelyidae Moringuidae (worm eels) Xenocongridae (false morays) Muraenidae (moray eels) Myrocongridae Suborder Nemichthyoidei Nemichthyidae (snipe eels) Serrivomeridae (sawtooth snipe eels) Cyemidae (bobtail snipe eels) Suborder Congroidei Congridae (congers) Muraenesocidae (conger pikes) Nettastomatidae (witch eels) Nessorhamphidae (duckbilled eels) Derichthyidae (neck eels) Ophichthidae (snake eels) Macrocephenchelyidae...
Saccopharyngiforms lack several bones, such as the symplectic bone, the bones of the opercle, and ribs. They also have no scales, pelvic fins, or swim bladder. The jaws are quite large, and several types are notable for being able to consume fish larger than themselves. Their myomeres (muscle segments) are V-shaped instead of W-shaped like in all other fish, and their lateral line has no pores, instead it is modified to groups of elevated tubules. At the tip of the gulper eel's tail is a small light organ that glows pink and can flash red. Monognathidae has lost its upper jaw. Fish anatomy is primarily governed by the physical characteristics of water, which is much denser than air, holds a relatively small amount of dissolved oxygen, and absorbs light more than does air. ... The gas bladder (also fish maw, less accurately swim bladder or air bladder) is an internal organ that contributes to the ability of a fish to control its buoyancy, and thus to stay at the current water depth, ascend, or descend without having to waste energy in swimming. ...
A 30 cm long GulperEel trawled during the NORFANZ expedition at a depth between the surface and 874m, Tasman Sea, south-east of Lord Howe Island, May 2003 (NMNZ P.38952).
The GulperEel has an elongate body with a luminous organ at the end of the tail.
The GulperEel occurs in midwaters of tropical and temperate seas worldwide.
