The Blue Parrotfish
By Yesenia Reyes
Blue parrotfishes, Scarus coeruleus (Bloch, 1786), aka blue kwabs, blue parrots, blue man, and kwabs, are uniformly blue in color with a yellow spot on top of the head, which fades as the fish grows. Adults have large scales and develop a protruding snout and extended upper and lower caudal (tail) fin lobes. Like other parrotfishes, blue parrotfishes have the characteristic beak-like jaws with fused teeth used for scraping algae from coral and other rocky substrates. They also have pharyngeal teeth that are used to grind ingested rocks into sand, which is then eliminated, creating new sand in the process.
Fact 2
Some male parrot fish maintain harems of females. If the dominant male dies, one of the females will change gender and color and become the dominant male.
Fact 3
Certain species of parrot fish envelope themselves in a transparent cocoon made of mucous secreted from an organ on their head
