 Today i read about parrotfish, parrotfish have many little cool features and are great for the Ocean environment. A group of parrot fish is called a harem, in the group there is one male called the supermale,  if the super male dies than the largest female will change its sex and become the supermale, plus in they will change there sex about 5 times a year. Secondly when they go to sleep they covered them selves in a mucous sleeping bag. Lastly Parrot fish will eat coral and then their feces will become white sand which then travels to white sand beaches.
