The Blue groper (Achoerodus viridis) is a saltwater fish of the family Labridae that grows up to 62 cm.
Description
The eastern blue groper is a large wrasse (Labridae) from the coastal waters of eastern Australia (New South Wales). The species reaches about 62 cm and inhabits rocky coastal reefs to about 40 m deep. It is a protogynous hermaphrodite: individuals begin as a brown to greenish female and the largest, dominant ones change into a deep-blue male. With its strong jaws and pharyngeal teeth it crushes crustaceans, molluscs and sea urchins. The species forms distinct pairs during breeding. The large, curious blue males are a favourite sight for divers and the species is protected in New South Wales.
