Taxonomy

Helicolenus was described by a genus in 1896 by the American ichthyologists George Brown Goode & Tarleton Hoffman Bean using Scorpaena dactyloptera as its type species which had originally been described by the Genevan physician, naturalist, chemist, botanist and ichthyologist François Étienne Delaroche in 1809. [1] The genus name is a compound of helikos which means "twisted" or "curved" but meaning "strong" according to Goode and Bean, possibly in error for hadros; and oleni meaning "elbow" or "arm", an allusion to the “strong pectoral fins” of H. dactylopterus. [2]

Species

There are 9 recognised species: [3]

Characteristics

Helicolenus fishes have a large head which bears spiny ridges and has a large mouth. There are 5 spines on the posterior and lower margin of the preoperculum and two obvious spines close to the posterior of the operculum. Their dorsal fins have 11-13 robust spines and 10 to 14 soft rays. [4] [5] Species in this genius vary in length from a standard length of 27 cm (11 in) in H. fedorovi and H. hilgendorfii up to a total length of 50 cm (20 in) in H. dactylopterus. [3]

Distribution and habitat

Helicolenus rockfishes are found in the Pacific and Atlantic oceans. They are benthic, demersal and bathydemersal fishes. [3]

Biology

Helicolenus rockfishes are ovoviviparous and fertilisation is internal. [6] They are predators of cephalopods, echinoderms, crustaceans and fishes. [5] They have been known to live for up to 42 years. [6]

Fisheries

Helicolenus rockfishes are commercially important species in fisheries in some regions such as southern Australia. [6]
