The species was first described in 1939 by the Australian ichthyologist Gilbert Percy Whiteley [4] . The holotype is a female with a length of 36.5 cm, caught in 1933, 48 km from Sydney , Australia (33 ° S. 151 ° W.) [5] .
Etmopterus molleri live in the western Pacific off the coast of Australia, New Zealand , Taiwan and Japan . Data on the capture of sharks of this species in the western Indian Ocean require confirmation, since erroneous determination of the species is possible. These sharks are found on the insular and continental slopes at a depth of 238 to 860 m.
The maximum registered size is 46 cm. The body is elongated, rather dense, with an elongated and thin tail stem. Large oval eyes stretched horizontally. Behind the eyes there are tiny sprinklers . Spines located at the base of both dorsal fins. The second dorsal fin is larger than the first. Pectoral fins small. The upper teeth have several teeth, the lower teeth are arranged in one continuous row. The body is covered with even longitudinal rows of placoid scales. The color is gray-brown on top, the lower part of the head and belly are black, the color border is sharp. Above and behind the ventral fins of it there is a short black mark [2] .
Etmopterus molleri breed by egg production. Probably lead a bottom life [6] . The size of newborns is about 15 cm [2] .
The species is not subject to commercial fishing. Occasionally as by-catch enters deep-sea nets. The International Union for Conservation of Nature has given this species the status of “Causes the least concern” [3] .
