Chlorurus microrhinos, the blunt-head parrotfish or steephead parrotfish, is a species of marine ray-finned fish, a parrotfish from the family Scaridae. [4] It is found in the Indo-Pacific region.
This species is one of the most widespread. It is present in the extreme east Indian Ocean and the Pacific Ocean, from the Ryukyu and Ogasawara Islands to Indonesia and the Australian Great Barrier Reef, Lord Howe Island, New Caledonia, and French Polynesia, and eastwards to Oceania (Hawaii and Easter Island excluded). [1]
Chlorurus microrhinos can be found in many different habitats, including lagoons, inshore reefs, and ocean reef fronts, from 2 to 50 m. At Guam, large individuals are seldom seen in shallow water. [1] This species occurs in schools that forage over lagoons and seaward reefs, which are rich in algae growth. The graze on filamentous algae. [5] This large species of parrotfish has an important ecological role in coral reefs because, as they graze, they excavate the coral to feed on algae. It grows quickly and can attain an age of 15 years old. [6] These parrotfish mainly feed on benthic algae and material scraped from corals, leaving exposed reef substrate. They usually swim in schools of about 40 fish, although juveniles are generally solitary. The flesh of the adults may be slightly toxic at some Pacific localities. [1]
Chlorurus microrhinos usually grows to be about 80 centimetres (31 in) long. These parrotfish are greenish blue, with a brilliant blue band behind the corner of the mouth and a wide blue patch along the head. Rarely, some individuals may be uniformly yellowish-tan. The cheek is crossed by an irregular line, below which the colour is usually greenish-yellow. Larger fishes are uniformly dark, greenish brown, turning greenish blue only with age, but they do not undergo as radical a colour change with growth as do other scarids.
They have nine dorsal spines, 10 dorsal soft rays, 3 anal spines, and 9 anal soft rays. The tail is crescent-shaped in large terminal males, while in juveniles it is rounded. Adults show large exposed blue-green tooth plates, with one or two canines on each side of the upper plate. [7]
Large males develop a prominent forehead (hence the common name of blunt-head parrotfishes). Juveniles are black with some horizontal white stripes. [8]
Some geographic variation exists between Red Sea, Western Indian Ocean, and Pacific populations, and an unusual reddish-tan phase occurs in the central Pacific. [9]
Chlorurus microrhinos was first formally described as Scarus microrhinos in 1854 by the Dutch medical doctor, ichthyologist, and herpetologist Pieter Bleeker (1819-1878), with the type locality given as Jakarta. [10] It forms a species complex with Chlorurus gibbus in the Red Sea and Chlorurus strongylocephalus in the Indian Ocean. [3]
Parrotfish are a group of fish species traditionally regarded as a family (Scaridae), but now often treated as a subfamily (Scarinae) or tribe (Scarini) of the wrasses (Labridae). 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.
The marbled parrotfish, also known as the seagrass parrotfish, is a species of marine ray-finned fish, a parrotfish from the family Scaridae and is the only known member of the genus Leptoscarus. It has a wide Indo-Pacific distribution and is also found in the southeastern Atlantic Ocean. It is a coastal species found in beds of sea grass and seaweed.
The princess parrotfish is a species of marine ray-finned fish, a parrotfish, in the family Scaridae. It is typically 20 to 25 centimetres long, found in the Caribbean, South Florida, the Bahamas, and Bermuda. Its behavior, similar to other parrotfishes, is to swim about the reef and sandy patches during the day, at depths between 3 and 25 metres, scraping algae on which it feeds.
The rusty parrotfish is a species of marine ray-finned fish, a parrotfish belonging to the family Scaridae. It is associated with reefs in the north western Indian Ocean and the Red Sea.
The queen parrotfish is a species of marine ray-finned fish, a parrotfish, in the family Scaridae. It is found on reefs in the tropical West Atlantic Ocean and the Caribbean Sea. Other common names include blownose, blue chub, blue parrotfish, blueman, joblin crow parrot, moontail, okra peji and slimy head. 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".
The blue parrotfish is a member of the parrotfish genus Scarus. It is found on coral reefs in shallow water in the tropical and subtropical parts of the western Atlantic Ocean and the Caribbean Sea. They usually forage in a group of 500 individuals for spawning and deterring predators while feeding.
Chlorurus sordidus, known commonly as the daisy parrotfish or bullethead parrotfish, is a species of marine fish in the family Scaridae.
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.
