Stomiati is one of five major euteleost lineages that were recently placed in one monophyly, a group of organisms all descending from one common ancestor. The five being a clade formed by Esociformes and Salmoniformes; second being the Stomiatii consisting of only Osmeriformes and Stomiiformes; Argentiniformes (excludes Alepocephaliformes); Galaxiiformes (excludes Lepidogalaxias); and Neotelestei. Stomiati are known for their large mouth, long throat/barbel, and no caudal filament.[2]
Osmeriformes
Osmeriformes smelts belong to the subcohort Protacanthopterygii. Osmeriformes mainly spawn in freshwater habitats except for the osmerid (family
Stomiiformes
Stomiiformes are an order of deep sea ray-finned fishes. These fishes are known, and named, for their absurdly large mouth openings. Stomiiformes is derived from Ancient Greek meaning “mouth” + “external form” which references their large mouth openings. Four (some may claim 5) different families comprise the order of Stomiiformes.[4]
Bioluminescence
The order of stomiiformes is linked to some of the most interesting deep sea dragonfishes. The genera of
Little is known about their ability to use and let alone sense light at such depths. Due to them lurking at a depth well below 500 m, they can only be observed in their natural habitat, and bringing one up to the surface alive is infeasible. The change in pressure the fish would experience would be too great and most certainly be fatal.[5]
