Like mentioned earlier, most of Maldives beach sand is formed from corals, but how exactly does sand materialise from the corals? Well, it is the work of the Parrotfish – they spend most of their day eating seaweed and polypus off the corals, except they also eat a bit of coral along with it. Their beak is so sharp it scrapes a layer of corals which is consumed along with the food. The chunks of corals are sliced up into small bits with the help of their teeth and then disposed of.
