7. Blue Parrotfish
It’s surprising how many rare creatures exist in this world, and a lot of them could be found in the deep blue sea. This blue parrotfish is commonly found in the tropical and even the subtropical parts of the western Atlantic ocean and in the Caribbean sea, on the coral reefs in the shallower parts of the waters. They are usually all blue with a yellow spot located on their heads that end up fading while they age. Their name stems from the large ‘beak’ that they have, similar to that of a parrot’s, a ‘beak’ which they use to scrape off algae and small organisms from the rocks. Their pharyngeal teeth are used to crush rocks that they end up eating into sand.
