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 1 to 26 metres (3.3 to 85.3 ft), and inhabits lagoons and reefs, forming colonies in sand sediments in confined areas.

Males can reach a maximum total length of 35 centimetres (14 in).
