Taxonomy
editThe lavender sculpin was first formally described by the French ichthyologist Charles Frédéric Girard in 1556 with its type locality[ given as San Miguel Island near San Diego in California.[1] Leiocottus hirundo is the only member of its genus. However, phylogenetically it falls within the diversity of the genus Clinocottus. It is a sister taxon to Clinocottus analis.[2] The 5th edition of Fishes of the World classifies the genus Leiocottus within the subfamily Cottinae of the family Cottidae,[3] however, other authors classify the genus within the subfamily Psychrolutinae of the family Psychrolutidae.[4]
Etymology
editThe lavender sculpin's genus name, Leiocottus, is a combination of leios meaning "smooth" with Cottus, the type genus of the family Cottidae. This is a reference to the smooth skin of this fish with no prickles or scales. The specific name hirundo is Latin for a swallow and is a reference to the similarity to Chelidonichthys lucerna Girard perceived in this species.[5]
Description
editThe lavender sculpin has dorsal fins which are supported by 9 or 10 spines and 16 or 17 soft rays while the anal fin has between 14 and 16 soft rays. The pelvic fins each have a single spine and 3 rays. The color is olive-green, brown, orange-brown or lavender with four saddle-like blotches along the back of the rear of the body and there are four brown bars on the lips.[6] This species grows to a maximum published total length of 25 cm (9.8 in).[7]
Distribution and habitat
editThe lavender sculpin is found in the eastern Pacific Ocean from southern California, United States to northern Baja California, Mexico. It lives from inshore waters to a depth of around 37 metres (121 ft).[7]
