Member genera include the flashlight fishes, fangtooth fishes, spinyfins, pineconefishes, redfishes, roughies, and slimeheads. A number of member species are caught commercially, most notably the orange roughy.[4] Some species have bioluminescent bacteria contained in pockets of skin or in light organs near the eyes, including the anomalopids and monocentrids.[5]
A recent phylogeny based on the work of Betancur-Rodriguez et al. 2017 shows Trachichthyiformes as a sister group of Beryciformes in the clade Berycimorpha.[6]
