Giant grouper

Epinephelus lanceolatus

The giant grouper, also known as the brindlebass, brown spotted cod, or bumblebee grouper, and as the Queensland groper in Australia, is the largest bony fish found in coral reefs, and the aquatic emblem of Queensland, Australia. It is found from near the surface to depths of 100 m at reefs throughout the Indo-Pacific region, with the exception of the Persian Gulf. It also enters estuaries. It reaches up to 2.7 m in length and 400 kg in weight; there are unconfirmed reports of it growing much bigger, up to 10 feet and 1320 pounds. Giant groupers feed on a variety of marine life, including small sharks and juvenile sea turtles. Due to overfishing, this species has declined drastically in many regions, and it is now considered Vulnerable by the IUCN.

This giant fish is similar to the Malabar grouper, and its colour changes with age. The giant grouper has a large mouth and a rounded tail. Juveniles have irregular black and yellow markings, while adults are green-grey to grey-brown with faint mottling, with numerous small black spots on the fins.

The first fish to undergo chemotherapy was "Bubba", a giant grouper at the Shedd Aquarium in Chicago, USA.
