|Scientific Name:||Myxine hubbsoides|
|Species Authority:||Wisner & McMillan, 1995|
|Red List Category & Criteria:||Data Deficient ver 3.1|
|Reviewer(s):||Polidoro, B., Knapp, L. & Carpenter, K.E.|
These species is only known from three type specimens collected off the coast of Chile. It's known restricted distribution likely overlaps with bottom trawling activities. It is listed as Data Deficient. More information is needed on this species distribution, population status, life history, biology, and impact of any potential major threats.
|Range Description:||This species is known only off central Chile, between Navidad and Punta Topocalma (Wisner and McMillan 1995).|
|FAO Marine Fishing Areas:||
Pacific – southeast

|Population:||The population of this species is only known from three type specimens taken off the central coast of Chile (Wisner and McMillan 1995).|
|Habitat and Ecology:||
This species is found on the lower continental slope at depths from 735-820 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 and bottom trawling activities along the continental slope in Chile have almost ceased, likely due to a collapse of the shallow water fisheries. While this species prefers deeper water it was likely vulnerable to historical bottom trawling activities. Mid-water fishing continues but this is not a threat to this species (R. Melendez pers. comm.). While the fishing threat has ceased, past activities may have significantly reduced the population through bycatch incidences and habitat destruction.|
|Conservation Actions:||Chile has recently passed a bill to ban bottom trawling in vulnerable marine ecosystems, such as deep seamounts, but it is not likely that this ban covers the known distribution of this species. More research is needed on this species' biology, population size, distribution and potential threats.|
