The family Scaridae is a family of chordates, vertebrate subphylum, teleost fish, rayfinfish, and perch. There are about 68 species of fish in 11 genera. It is found in tropical seas.
Like the rumped fish, parrotfish undergo a sexual transition after the female matures. Generally speaking, the male fish has a light blue body, and the female fish has a red color, and it is difficult to distinguish whether the female is of the same species when viewed from the outside. Most parrotfish have juvenile and adult fish that differ in color and markings, and even have huge differences. Juveniles and females are brown in color with 5 to 6 blue transverse bands on the side of the body. The male is blue all over and pale brown on the leading edge of the scales. The dorsal, and caudal fins all have blue stripes. Tail truncation. Body length up to 80 cm. However, due to the fact that the body color of parrotfish is mainly blue and green, and the difference in color is not obvious, it is more difficult to identify the species of parrotfish from the appearance, and I believe this is also the same feeling of most divers.
Nocturnal parrotfish hide in coral crevices or rock hideaways, and when they sleep, they secrete a thin transparent mucus membrane to cover their bodies, which is said to be a move that parrotfish avoid killing in order to prevent predators from smelling their own odors when sleeping.
Parrotfish family
Parrotfish range in size from tens of centimeters to more than a meter, and there are about 96 species worldwide, most of which are important food fish and are likely to be caught or netted. Unlike other reef fish that can be reared as ornamental fish, parrotfish are more difficult to feed in aquariums because they have to often scrape dead coral branches to prevent their teeth from growing too long.
