Description

The squaretail coralgrouper is a large grouper from the Indo-Pacific, from the Red Sea to Samoa and Australia. The species grows to about 80 cm and has a brown-red to olive body densely covered with small blue, dark-edged spots, and an almost straight tail margin. As a top reef predator it hunts other reef fish by day. It gathers in spawning aggregations around the full moon and is a protogynous hermaphrodite. Large specimens can cause ciguatera poisoning. Through fishing of spawning concentrations it is listed as Vulnerable (VU) on the IUCN Red List.
