Description

The narrow worm eel is a small snake eel of the family Ophichthidae from the Indo-West Pacific. The species reaches about 27 cm and has a very slender, eel-like, sand-coloured body with a hard, pointed tail with which it burrows backwards into the sand. It is common in tide pools and mangrove swamps and is also seen on sand bottoms near reefs. The diet consists of small bottom invertebrates that it locates in and on the sediment. Owing to its hidden, burrowing habits the species is little noticed and has no fishery value.
