Evidence: 100 • authority: 72

Aulopiformes is a diverse order of marine ray-finned fish consisting of some 15 extant and several prehistoric families with about 45 genera and over 230 species. The common names grinners, lizardfishes and allies, or aulopiforms are sometimes used for this group. They are included in the superorder Cyclosquamata, though modern taxonomists consider this superorder to be unwarranted. Many extant aulopiforms are deep-sea fishes, with some species recognized as being hermaphroditic, a number of which are able to self-fertilise. Some are benthic, but most are pelagic swimmers (nektonic). A clade of Aulopiformes, the suborder Enchodontoidei and its many constituent families, were dominant nekton…

Estimating divergence times of lizardfishes and their allies (Euteleostei: Aulopiformes) and the timing of deep-sea adaptations.. The divergence times of lizardfishes (Euteleostei: Aulopiformes) are estimated utilizing a Bayesian approach in combination with knowledge of the fossil record of teleosts and a taxonomic review of fossil aulopiform taxa. These results are integrated with a study of character evolution regarding deep-sea evolutionary adaptations in the clade, including simultaneous hermaphroditism and tubular eyes. Divergence time estimations recover that the stem species of the lizardfishes arose during the Early Cretaceous/Late Jurassic in a marine environment with separate sex…

Greeneyes are deep-sea aulopiform marine fishes in the small family Chlorophthalmidae. Thought to have a circumglobal distribution in tropical and temperate waters, the family contains just 18 species in two genera. The family name Chlorophthalmidae derives from the Greek words chloros meaning "green" and ophthalmos meaning "eye". Some species are of interest to commercial and subsistence fisheries; the fish are made into fish meal or sold fresh. The only known prehistoric member of this group is Omiodon, a stem-chlorophthalmid known from a complete fossil skeleton from the early Eocene of Italy.Acrognathus from the Cenomanian of England & Lebanon was previously classified in this family, b…

Deep-sea fish are fish that live in the darkness below the sunlit surface waters, that is below the epipelagic or photic zone of the sea. The lanternfish is, by far, the most common deep-sea fish. Other deep-sea fishes include the flashlight fish, cookiecutter shark, bristlemouths, anglerfish, viperfish, and some species of eelpout. Only about 2% of known marine species inhabit the pelagic environment. This means that they live in the water column as opposed to the benthic organisms that live in or on the sea floor. Deep-sea organisms generally inhabit bathypelagic (1–4 km; 0.62–2.49 mi deep) and abyssopelagic (4–6 km; 2.5–3.7 mi deep) zones. However, characteristics of deep-sea organisms,…
