Length at first maturity / Size / Weight / Age
Maturity: Lm 75.5, range 69 - ? cm
Max length : 150 cm TL male/unsexed; (Ref. 12382); common length : 80.0 cm TL male/unsexed; (Ref. 3397); max. published weight: 6.5 kg (Ref. 58348); max. reported age: 38 years (Ref. 58348)
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).
Migrate to offshore waters to spawn (Ref. 98745).
