It is able to survive in water with a low salt concentration.[3] Males can reach a maximum total length of 47.2 centimetres.[2] The eels' diet consists primarily of benthic gastropods and worms, and bivalves.[3] Due to its wide distribution, lack of threats and lack of observed population declines, the IUCN redlist currently lists the Pacific mud eel as Least Concern.[3] References1. ^Common names for Pythonichthys asodes at www.fishbase.org. {{Taxonbar|from=Q920083}}{{Anguilliformes-stub}}2. ^1 2 Pythonichthys asodes {{webarchive|url=https://archive.is/20130412204221/http://fishbase.mnhn.fr/summary/Pythonichthys-asodes.html |date=2013-04-12 }} at www.fishbase.org. 3. ^1 2 3 Pythonichthys asodes at the IUCN redlist. 7 : Heterenchelyidae|Fish of the Pacific Ocean|Fish of North America|Fish of Central America|Fish of Mexican Pacific coast|Fish described in 1972|Least concern biota of North America |
