Common Name(s):
English Strickrott's Hagfish

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2011
Date Assessed: 2009-11-11

This species is only known from a single specimen collected from a hydrothermal vent at 2,211 m. There are no major threats known to this very deep water species. It is listed as Least Concern. More research is needed on this species distribution, population status, biology, and depth range as current knowledge is only based on the holotype.

Geographic Range [top]

Range Description:This species is known only from the type locality, East Pacific Rise, 37°47.363'S, 110°54.905'W. It is found in the eastern South Pacific along the East Pacific Rise vent site. There is a possible wider distribution 30° northward at a depth range down to 2,900 m if the individuals filmed at Grommit, Oasis, and Yaquina vent sites are the same species (Møller and Jones 2007).

Population:This species is only known from the holotype.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:The single known specimen (314 mm total length (TL)) was collected from a hydrothermal vent site, at 2,211 m depth.

This specimen is the first record of a hagfish species in a hydrothermal vent and the fourth record of a hagfish species below 2,000 m.

Threats [top]

Major Threat(s): There are no known threats to this species; it is found in very deep waters.

Conservation Actions [top]

Conservation Actions: There are no conservation measures in place, but more research is needed on this species' biology, population size, distribution, depth range and potential impacts.
