|Scientific Name:||Eptatretus profundus|
|Species Authority:||(Barnard, 1923)|
Heptatretus profundus Barnard, 1923
|Red List Category & Criteria:||Least Concern ver 3.1|
|Reviewer(s):||Polidoro, B., Knapp, L. & Carpenter, K.E.|
This species is only known from a few deep water specimens off the coast of South Africa. There are no known threats to this species. However, may be caught incidentally 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 this species has a limited range and is potentially susceptible to deep-sea trawling along the continental slope.
|Range Description:||This species is found off the coast of South Africa, from off Lambert’s Bay to Cape Agulhas (Mincarone, unpubl. data).|
|FAO Marine Fishing Areas:||
Atlantic – southeast
|Lower depth limit (metres):||1150|
|Upper depth limit (metres):||490|

|Population:||This species' population is only known by a few specimens so abundance levels are unknown. It has been known by the holotype for many years but more specimens have been recorded in museums more recently (Mincarone, unpubl. data).|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This species is located on the continental slope at depths from 490-1,150 m.
The copulatory organ is absent in this species. The gonads of hagfishes are situated in the peritoneal cavity. The ovary is found in the anterior portion of the gonad, and the testis is found in the posterior part. The animal becomes female if the cranial part of the gonad develops or male if the caudal part undergoes differentiation. If none develops, then the animal becomes sterile. If both anterior and posterior parts develop, then the animal becomes a functional hermaphrodite. However, hermaphroditism being characterised as functional needs to be validated by more reproduction studies (Patzner 1998).
|Major Threat(s):||There are no known direct threats to this species, but its limited range may be vulnerable to deep-sea trawling in this highly productive coastal region.|
|Conservation Actions:||There are no conservation measures in place, but more research needed on this species' biology, population size, distribution and impacts.|
