Zaniolepis, the combfishes, is a genus of marine ray-finned fish, it is one of two genera in the family Zaniolepididae. These fishes are native to the eastern Pacific Ocean. Z. frenata that was a source of food to the Native American inhabitants of San Nicolas Island off the coast of southern California, United States during the Middle Holocene.[1]

Taxonomy

Zaniolepis was first proposed as a monospecific genus in 1858 by the French zoologist Charles Frédéric Girard when he described Z. longispinis from Fort Steilacoom on Puget Sound in Washington.[2] This genus is one of two genera in the family Zaniolepidae, each of which is classified within a monotypic subfamily.[3] The subfamily Zaniolepinae, along with the Oxylebiinae, haves been classified as two subfamilies in the Hexagrammidae.[4]

Etymology

Zaniolepis is a combination of xanion, which is a Greek word for a comb used to card wool, and lepis, meaning "scale", referring to the overlapping, almost ctenoid scales of Z. latipinnis.[5]

Species

The currently recognized species in this genus are:[6]

Characteristics

Zaniolepis combfishes have a deep incision in the rear third their dorsal fin and the first 3 spines in the dorsal fin are highly elongated, extremely so in Z. latipinnis. The anal fin contains 3 spines while the first 2 rays in the pelvic fins are long and robust and extend past the origin of the anal fin. The caudal fin truncated.[3] These fishes reach a maximum length of Template:Cvt.[6]

Distribution and habitat

Zaniolepis combfishes are found in the eastern North Pacific Ocean from Alaska to Baja California. They are benthic fishes.[6]
