The Zaniolepididae is a family of marine ray-finned fishes classified within the suborder Cottoidei of the order Scorpaeniformes. They are found in the North Pacific Ocean.
Zaniolepididae was first proposed as a family in 1883 by the American ichthyologists David Starr Jordan and Charles Henry Gilbert. this taxon has been classified as the subfamily Zaniolepinae within the Hexagrammidae.[1] This family is classified within its own superfamily, the Zaniolepidoidea, within the suborder Cottoidei of the Scorpaeniformes.[2] Other workers have found that if the Scorpaeniformes, as delimited in Fishes of the World, is not included in the Perciformes it renders the Perciformes paraphyletic. These workers retain the Cottoidei as a suborder within the Perciformes while reclassifying Zaniolepidoidea as the infraorder Zaniolepidoales.[3]
Zaniolepididae has 2 genera classified within it, each within its own monotypic subfamily:[2]
Zaniolepididae is characterised by having an incision between the first and second dorsal fins and by having an anal fin with 3 or 4 spines. The caudal fin may be rounded or truncate, there is one complete lateral line and the scales are ctenoid.[2] These are medium sized fishes with maximum total lengths of .
Zaniolepidiae are endemic to the eastern North Pacific Ocean from Alaska south to Baja California.[1]
Zaniolepididae has one species, Zaniolepis frenata, which has been recorded as a source of food for the Native American inhabitants of San Nicolas Island off the coast of Southern California during the Middle Holocene.[4]
