The Smallfin worm-eel (Pseudomyrophis micropinna, also known as the Plain worm eel[1]) is an eel in the family Ophichthidae (worm/snake eels).[2] It was described by Charles Barkley Wade in 1946.[3] It is a marine, tropical eel which is known from the eastern central and southeastern Pacific Ocean, including Nicaragua, Colombia, Panama and Costa Rica.[4] It dwells at a depth range of 100mto200mm (300feetto700feetm), and inhabits sediments of mud. Males can reach a maximum total length of 16cm (06inches).[2]
Due to its wide distribution, lack of known threats, and lack of observed population decline, the IUCN redlist currently lists the Smallfin worm-eel as Least Concern.[4]
