Diagnostic Description

Most easily distinguished from N. scolopaceus by its pale color; has more postorbital and preopercular pores. Rectangle formed by the lateral line pores is shorter and higher than in scolopaceus. Resembles N. curvirostris in its pale color but the subcutaneous dark bars are not as evident. May be instantly distinguished from curvirostris by the more numerous postorbital and preopercular pores and the much shorter and higher rectangle formed by the lateral line pores. Has smaller teeth than curvirostris.

Nemichthys larseni

Nemichthys larseni is an eel in the family Nemichthyidae (snipe eels).[1] It was described by Jørgen G. Nielsen and David G. Smith in 1978.[2] It is a marine, deep water-dwelling eel which is known from the eastern Pacific Ocean, including Oregon and Hawaii, USA, Mexico, and the Gulf of California. It dwells at a depth range of 0 to 1,000 metres (0 to 3,281 ft). Males can reach a maximum total length of 161 centimetres (63 in).[1]

The species epithet "larseni" was given in honour of Verner Larsen, credited with starting the study of the species at the University of Copenhagen.[1]
