This species is only known from a few deep water specimens taken in the North Atlantic. There are no known threats to this species. However, may be caught in bottom trawling fisheries within its range. It is listed as Least Concern. More research is needed on this species distribution, population, biology, life history, and potential threats, especially as there are few records to understand its distribution and the species was only described in 2005. It has likely been previously mistaken for Myxine glutinosa in bycatch and scientific survey records.

Geographic Range [top]

Range Description:This species is known from the North Atlantic, eastern Davis Strait, Denmark Strait, Reykjanes Ridge, and southeast of Iceland. The disjunctive distribution is a result of a very limited sampling effort in the waters around southern Greenland (Møller et al. 2005).

It occurs sympatrically with Myxine glutinosa, although with a rather limited overlap in vertical distribution (752-1556 vs. 64-782 m) and no documented capture of both species in the same haul or trap exists.

Population [top]

Population:This population is only known from a few type specimens collected at 17 locations.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is usually taken from muddy bottoms and cold waters (3.7-4.7°C) on the lower slope at depths from 752-1,556 m. According to Møller et al. (2005), the eggs of a single damaged female were in various stages of maturation, elliptical, up to 23.6 x 8.5 mm. All eggs were in mesenteries and no anchor filaments were found (Moller et al. 2005).

Threats [top]

Major Threat(s): There are no known direct threats to this deep water species. There are deep water fisheries active within the currently known distribution range but no records are being reporting from by-catch incidences. This is likely due to this species being lumped with Myxine glutinosa as by-catch since the species was only described in 2005.

Conservation Actions [top]

Conservation Actions: There are no conservation measures in place, but more research is needed on this species' biology, population size, distribution and impact of deep-water trawling activities.
