Chlorurus sordidus, known commonly as the daisy parrotfish or bullethead parrotfish, is a species of marine fish in the family Scaridae.
The initial phase has very variable colouration. The smaller fishes can be a uniform dark brown to light gray and they may or may not possess a light band surrounding a dark spot on the caudal peduncle. Larger specimens can show a series of irregular rows of small, light spots towards the tail or they may have the light band surrounding the dark spot on the caudal peduncle. The terminal phase, male, is also variable and may have a large tan area on the flanks or on its caudal peduncle. It has a rounded snout. [2]
Chlorurus sordidus is a medium size fish and can reach a maximum size of 40 cm (16 in) length. [2]
Chlorurus sordidus is widespread throughout the tropical waters of the Indo-Pacific region, Red Sea included. [3]
Before going to sleep, Chlorurus sordidus secretes a mucus which surrounds the fish in a complete cocoon. The purpose of this mucus cocoon is not completely understood, but one theory is that it protects the fish from parasitic gnathiids. [4] This species is known to be predated on by the honeycomb grouper (Epinephelus merra) and the coral trout (Plectropomus leopardus), its parasites include the monogenean Benedenia scari . [3] It is a sociable fish which schools with other parrotfishes such as Scarus psittacus . [5]
Chlorurus sordidus is one of the most widespread species of parrotfish, and it is highly variable with some of the geographically determined forms probably being at least subspecies. It occurs in both coral rich and open pavement areas of shallow reef flats, in lagoon reefs and seaward reefs, it can also be found at drop-offs. The juveniles inhabit areas of coral rubble in reef flats and lagoons. The juveniles and females in their initial phase form large groups that move long distances between their feeding grounds and the areas used for sleeping at night. They feed on benthic algae. This species is a protogynous hermaphrodite and the sex change occurs when the attain a total length of 35.1–47.2 centimetres (13.8–18.6 in). [2]
Chlorurus sordidus has been split by some authorities and the Red Sea dn Indian Ocean populations are regarded as C. sordidus while Chlorurus spilurus occurs in the Pacific and Eastern Indian Ocean, this is based on mitochondrial DNA sequencing and on morphological data. It is also probable that the Red Sea population will also be demonstrated to be specifically distinct. [1] Scarus sordidus was described by the Swedish explorer, orientalist and naturalist Peter Forsskål (1732-1763), the description was published in 1775 with the type locality being Hurghada in Egypt.

Parrotfishes are a group of fish species regarded as a family (Scaridae), or a subfamily (Scarinae) of the wrasses. With roughly 95 species, this group's largest species richness is in the Indo-Pacific. They are found in coral reefs, rocky coasts, and seagrass beds, and can play a significant role in bioerosion.

Scarus is a genus of parrotfishes. With 52 currently recognised extant species, it is by far the largest genus in this family. The vast majority are found at reefs in the Indo-Pacific, but a small number of species are found in the warmer parts of the eastern Pacific and the western Atlantic, with a single species, Scarus hoefleri in the eastern Atlantic. Most are very colourful, and have strikingly different initial and terminal phases. Adults of most species reach maximum lengths of between 30 and 50 cm (12–20 in), but the rainbow parrotfish can grow to lengths of 1.2 m (3.9 ft).

The young males and adult female queen parrotfish are a reddish-brown color, and quite different in appearance from the bluish-green color of the final phase male. This is a common species throughout its range and the International Union for Conservation of Nature has rated its conservation status as "least concern".

Scarus niger, common names the swarthy parrotfish, dusky parrotfish, and black parrotfish, is a species of parrotfish. It is in the phylum Chordata, class Actinopterygii, and family Scaridae. Like other members of its family, it has characteristic 10 dorsal soft rays, 9 dorsal spines, 9 anal soft rays, and 3 anal spines, It is found in Indo-West and Central Pacific, from the Red Sea, north to Japan, south to Australia and east to French Polynesia. It is found in lagoons, channels and outer reefs slopes on the depths of 2 to 20 metres. The dusky parrotfish often lives in solitude, but males may also live in a small group of mating females. The dusky parrotfish is primarily herbivorous, and its main source of food is benthic algae. At maturity, the fish is approximately 230-240mm long and weighs around 240g.
