Turret snake eel

The turret snake eel (Brachysomophis umbonis) is an eel in the family Ophichthidae (worm/snake eels). It was described by John E. McCosker and John Ernest Randall in 2001. It is a marine, tropical eel which is known from the Indo-Western Pacific, including Indonesia and the Philippines. It dwells at a depth range of 14 to 18 m, and inhabits sand and reefs. Males can reach a maximum total length of 13.9 cm.

The species epithet, "umbonis", meaning "rounded protuberance" in Latin, refers to the prominent lateral projections of the eel's cheeks.
