Blue groper

Achoerodus is a genus of wrasses collectively known as blue gropers. They are found in the coastal waters of southern Australia and distinguished by the bright blue colouring of the adult males.

The thick-bodied blue gropers have peg teeth, heavy scales, large tails and thick lips. Juveniles are brown to green brown. Adult females are brown to greenish-yellow. Each scale may have a darker red spot. The adult males have the bright blue colouring that give the fish their name. The blue can range from deep navy to cobalt blue, and there may also be darker or yellow-orange spots or lines around the eyes.
