Ecology
Juvenile green humphead parrotfish are found in lagoons, often in seagrass beds, and adults are found in clear outer lagoon and seaward reefs up to depths of at least 30 m. They are usually found in small groups, and they feed on benthic algae and live corals. They may ram their head against corals to facilitate feeding. Each adult fish ingests over 5 tons of structural reef carbonates per year, contributing significantly to the bioerosion of reefs. They sleep in caves and shipwrecks at night.
