Aulopiformes is an order of ray-finned fish consisting of thirteen living families of marine fish. They are grouped together on the strength of common features of pharyngobranchial structure. Scientific classification or biological classification refers to how biologists group and categorize extinct and living species of organisms. ...

Many of the aulopiforms are deepsea fish, and some species are hermaphrodites. The 1st-century BC sculpture The Reclining Hermaphrodite, in the Museo Palazzo Massimo Alle Terme in Rome In zoology, a hermaphrodite is an organism of a species whose members possess both male and female sexual organs during their lives. ...
Examples of primitive characters include abdominal pelvic fins with 8–12 rays, the absence of fin spines, the presence of an adipose fin (a structure consisting of fatty tissue located between the dorsal fin and the caudal fin), and scales that are cycloid or rounded in shape.
Among the midwater aulopiformes are the large lancetfishes (two species within Alepisauridae), which are distinguished by a long, sail-like dorsal fin that stretches from the head nearly to the adipose fin and may grow to nearly 7 ft (more than 200 cm) in length.
Midwater and deep-water aulopiform fishes that may or may not have tubular eyes and are distinguished by fang-like teeth and a lack of scales include the sabertooth fishes (seven species within Evermannellidae) and the hammerjaw (Omosudidae, one species).
