About this species

The saddled snake-eel, also known commonly as the halfbanded snake-eel, the banded snake eel, or the culverin, is an eel in the family Ophichthidae. It was described by George Tradescant Lay and Edward Turner Bennett in 1839, originally under the genus Ophisurus. It is a marine, tropical eel which is known from the Indo-Pacific and southeastern Atlantic Ocean, including East and South Africa, the Hawaiian Islands, the Marquesan Islands, the Mangaréva islands, Japan, and Australia. It dwells at a depth range of 0 to 70 metres, most often around 0 to 10 metres, and inhabits lagoons and reefs, in which it forms burrows in beds of seagrass and sandy areas. Males can reach a maximum total length of 66 centimetres (2.17 ft).
