Body shape (shape guide): eel-like; Cross section: compressed.
Occurs in coral-rich areas of lagoon and seaward reefs from depths of 1 m to at least 36 m. Prefers very shallow depth and juveniles often in intertidal zones (Ref. 30404). Benthic (Ref. 58302). Often seen hunting during low tide among partly exposed reefs (Ref. 48635). Feeds mainly on fishes, also on crustaceans, by day and probably also at night (Ref. 13550). Caught with various nets (Ref. 30573). Minimum depth reported taken from Ref. 86942.
