Size:

Maximum size up to 180 cm TL; birth size 48–50 cm TL.

Distribution:

Found in the tropical Indian Ocean,western central Pacific, and eastern Mediterranean Sea.

Habitat:

Found on coral reefs and reef flats, and near reef drop-offs, as well as in mangrove habitats during high tides and occasionally in brackish waters. A shallow dwelling species, found from the surface to only a few meters depth.

Biology:

Feeds primarily on bony fish, but also crustaceans, cephalopods other molluscs and terrestrial snakes. Length at maturity is at 96–130 and 91–105 cm TL for females and males respectively. Age at maturity is around 8.5 years and 4.2 years for females and males respectively for north-eastern Australian populations. Females give birth to 2–4 pups each November after a 8–9 month gestation for north-eastern Australian populations; gestation longer in other areas (e.g. 16 months for Red Sea populations). This species has a viviparous with yolk-sac placenta reproductive mode. Attains a maximum age of at least 15 years for females and 10 years for males.

Indonesian fisheries:

Caught by inshore longline and gillnet fisheries, and probably adversely affected by dynamite fishing. Utilised for its fins and meat, but of limited value due to its size.
