Every night, certain species of parrotfish envelope themselves in a transparent cocoon made of mucous secreted from an organ on their head. Parrotfishes. Nonetheless, according to the World Register of Marine Species the group is divided into two subfamilies as follows : More recent studies retain the Scaridae as a family but place it alongside the wrasses of the family Labridae and the weed whitings Odacidae in the order Labriformes, part of the Percomorpha. This means that some females do not change sex (they remain females throughout their lives), the ones that do change from female to male do it while still immature (reproductively functioning females do not change to males) and there are no males with female-like colors (the initial phase males in other parrotfish).

Most species are sequential hermaphrodites, starting as females (known as the initial phase) and then changing to males (the terminal phase). Several of the other species grow up … (2009). Rotjan (2018).  Mature excavating species include Bolbometopon muricatum, Cetoscarus, Chlorurus and Sparisoma viride.  Nevertheless, when they do eat coral polyps, localized coral death can occur.

Along with parrotfish and damselfish, these animals are mostly herbivores, and together they form the largest part of the fish biomass of most reefs (Thresher, 1980). There's its sex, which they can change repeatedly throughout their lives, and their coloration and patterns, which are a classification nightmare, varying greatly, even among the males, females, and juveniles of the same species.
