Aspect: Redtail Parrotfish tends to have a slightly more pointed nose. All parrotfishes sport a stong elongated oval body boasting large scales, prominent mouth with bill-like frontal teeth (hence the name) with which they bite away at coral. Difficult to believe that initial and terminal phases seen here belong to the same species. Population: Terminal phase relatively rare around Ilets Pigeon. Notable feature: Initial phase (top in title picture): Mottled white and red-brown. Terminal phase: blue-green, with reddish crescent in tail fin. Ventral area is yellowish, but area immediately behind the pectoral fins is more resolutely blue. Environment: Swims around rocks and coral boulders from which it violently bites off coral and algae. Behaviour: Can be approached within one or two metres.
