The redfin worm-eel (Scolecenchelys laticaudata, also known as the pearlbelly snake-eel[1]) is an eel in the family Ophichthidae (worm/snake eels).[2] It was described by James Douglas Ogilby in 1897, originally under the genus Myropterura.[3] It is a marine, tropical eel which is known from the Indo-Pacific and southeastern Atlantic Ocean, including the Red Sea, East and South Africa, Ducie Island, and Lord Howe Island. It dwells at a depth range of 1mto26mm (03feetto85feetm), and inhabits lagoons and reefs, forming colonies in sand sediments in confined areas. Males can reach a maximum total length of 35cm (14inches).[2]
