Description

The harlequin snake eel is a snake eel of the family Ophichthidae from the Indo-Pacific. The species grows to about 97 cm and has an elongate, snake-like body that is strikingly white with black bands or saddles. That pattern closely resembles that of the venomous banded sea krait; because predators mistake the eel for the dangerous snake, it gains protection - a form of Batesian mimicry. It lives on shallow sandy flats and in seagrass beds, often largely buried in the sand. As a bottom hunter it searches for small crustaceans and small fishes. The snake eel itself is not venomous and is harmless to humans.
