Bumphead Parrotfish - Bolbometopon muricatum
This Bumphead Parrotfish - Bolbometopon muricatum are the largest among Parrotfish, growing up to length of 1.3 meters.
They likes to congregrate in big numbers and over in Sipadan Island, in the early morning, as they wakes up from their night sleep, they starts to move to the shallow waters where they can find their favourite food - hard corals. They bite on hard corals where algae and other organism grows on them. They are not able to digest the hard corals which actually ended up as powdery sands when they poop. So, in essence, all the super fine powdery sands in nice beaches are mostly the shit of Parrotfishes!
