Biology     Glossary (e.g. epibenthic)

A nocturnal and territorial species (Ref. 12382), commonly lurking in holes, and writhing snakelike through crevices, under rocks or corals. Feeds on fish, crabs and squid (Ref. 12382). It seldom attacks unless provoked (Ref. 3256). A gonochoristic species (Ref. 32169). Utilized fresh and eaten broiled, boiled and baked; the skin can be used for leather (Ref. 9987).
