Bumphead parrotfish (Bolbometopon muricatum). This species is the largest of all parrotfish. It is found in the Indo-Pacific region. This fish undergoes a change of colour as it develops, with the primary phase as a dull grey with white spots, which gradually becomes dark green. Juveniles are found in lagoons and adults in clear water reefs. Its main source of food is benthic algae and live corals. It sleeps in caves and shipwrecks at night. Photographed in Malaysia, Indo-Pacific.
