|Scientific Name:||Eptatretus strahani|
|Species Authority:||McMillan & Wisner, 1984|
|Red List Category & Criteria:||Data Deficient ver 3.1|
|Reviewer(s):||Polidoro, B., Knapp, L. & Carpenter, K.E.|
This species is only known from seven specimens: five collected in one location in the Philippines and two collected off western Australia. The Philippines is an area with destructive fishing activities, including blast fishing. The extent of impact is not known due to limited knowledge of this species' depth and distribution range. It is listed as Data Deficient. More research is needed to determine this species distribution, population status, life history, biology, and impact of potential threats.
|Range Description:||This species is known from the type locality, off northwestern Lubang Islands, Philippines, and two additional specimens recently identified off western Australia (Mincarone and Fernholm 2010).|
|FAO Marine Fishing Areas:||
Indian Ocean – eastern; Pacific – western central

|Population:||This species is only known from five type specimens collected off northwestern Lubang Islands, Philippines, and two specimens from off western Australia (Mincarone and Fernholm 2010).|
|Habitat and Ecology:||
This species is found in relatively shallow waters (189 m) off Philippines, and on the upper slope (405-430 m) off western Australia.
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 it was found in a relatively shallow location threatened by destructive fishing activities, including blast fishing. Little is known about the species' depth and distribution range so the extent of impact of potential threats on the species' habitat cannot be determined.|
|Conservation Actions:||Only small locally managed marine areas exist but these are insufficient for safeguarding deeper water habitat. More research is needed on this species' biology, population size, distribution and impact of fishing.|
