Lycodichthys is a genus of marine ray-finned fish belonging to the family Zoarcidae, the eelpouts. They are found in the Southern Ocean.
Taxonomy
Lycodichthys was first proposed as a monospecific genus in 1911 by the German zoologist Paul Pappenheim when he described L. antarcticus giving its type locality as the Gauss winter station on the coast of Kaiser Wilhelm II Land in Antarctica.[2][3] in n1962 the American ichthyologist Hugh Hamilton DeWitt described a second species in the genus, L. dearborni.[4] This genus is classified in the subfamily Lycodinae, one of four subfamilies in the family Zoarcidae, the eelpouts.[5]
Etymology
Lycodichthys combines the name of the Northern genus Lycodes with ichthys, meaning "fish", as this genus closely resembles Lycodes in the shape of the body and fins.[6]
Species
Lycodichthys contains the following species:[4]
- Lycodichthys antarcticus Pappenheim, 1911
- Lycodichthys dearborni (DeWitt, 1962)
Characteristics
Lycodichthys eelpouts have robust bodies which have a depth which is equal to 8.4% to 12.7% of their standard length. They have firm, thick skin and both scales and the lateral line are present. Pelvic fins can be either present or absent. There are five suborbital bones and five pores on the head. The gill slit does not typically extend as far as the lower edge of the base of the pectoral fin. There are no vomerine or palatine teeth.[7] Both species within Lyodichthys are similar in sizee with maximum published of {{cvt|24|cm{{ for L. antarcticus and 23 cm (9.1 in) for L. dearbornii.[4]
