Bumphead Parrotfish Bolbometopon muricatum

Parrotfish are named after their beaklike fused dentition to scrape algae off rock and coral. The Bumphead Parrotfish, also called Green Humphead, are a greyish green colour and native to tropical reefs of the Indo-Pacific.

They are the largest parrotfish, growing to 1.5 metres (4.9 feet) long and weighing up to 75kg.

These herbivorous, slow-growing giants are vulnerable through overfishing.
