Description

The blue parrotfish is a parrotfish (Scaridae) from the western Atlantic Ocean. The species grows to about 1 metre and is entirely blue; older males develop a bump on the head. With its parrot-like, beak-fused teeth it scrapes algae and small organisms from coral and rock, and bites into the sand. Juveniles live in seagrass beds (Thalassia). It forms large spawning aggregations. Like many parrotfishes it is a protogynous hermaphrodite. The species is harmless to humans.
