The Crocodile snake eel (Brachysomophis crocodilinus, also known as the Henshaw's snake eel or the Reptilian snake eel) is an eel in the family Ophichthidae (worm/snake eels). It was described by Edward Turner Bennett in 1833. It is a tropical, marine eel which is known from the Indo-Pacific, including East Africa, the Society Islands, Japan, and Australia. Males can reach a maximum total length of 120 centimetres. It dwells at a depth range of 0–30 metres (most often at around 0–2 m), and inhabits coral reefs. It forms burrows in sand and lies in wait to ambush prey, leaving only its eyes exposed. Its diet consists of octopuses, species of Calcarina, and finfish.
