Epinephelus lanceolatus

Wide Indo-Pacific distribution: Red Sea and East Africa south to South Africa, across the Indian Ocean, throughout Southeast Asia, north to southern Japan, east to Hawaii and Pitcairn Islands, south to Australia (NSW on east coast, WA on west).

When to spot

Can be encountered year-round. Often more active feeders at dawn/dusk but can be seen resting during the day.

Water

Tropical and subtropical waters.

How to spot

Associated with reefs, found in caves, wrecks, harbours, and sometimes silty/muddy bottoms or estuaries. Found from shallow waters (1m) down to 100m. Juveniles are secretive on reefs. Adults are often solitary and territorial. Look for them inside large structures (wrecks, cave mouths) or resting near prominent reef features. Can be curious but maintain respectful distance.
