It is a marine, tropical eel which is known from the eastern central and southeastern Pacific Ocean, including Chile, Costa Rica, Colombia, El Salvador, Ecuador, Mexico, Guatemala, Nicaragua, Panama, Honduras, and Peru.

[1] It dwells at a depth range of 0 to 60 metres (0 to 200 ft), and inhabits benthic sediments of mud and sand.

Males can reach a maximum total length of 74 centimetres (29 in), but more commonly reach a TL of 60 centimetres (24 in).

[3] The spotted snake-eel is of no commercial interest to fisheries.

[3] Due to its wide distribution in the eastern Pacific, its lack of known threats and lack of observed population decline, the IUCN redlist currently lists the species as Least Concern.
