Parrotfish
Parrotfishes are a group of about 90 fish species regarded as a Family (biology), family (Scaridae), or a subfamily (Scarinae) of the wrasses. With about 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. Description Parrotfish are named for their dentition, which is distinct from other fish, including other labrids. Their numerous teeth are arranged in a tightly packed mosaic on the external surface of their jaw bones, forming a parrot-like beak with which they rasp algae from coral and other rocky substrates (which contributes to the process of bioerosion). Maximum sizes vary within the family, with the majority of species reaching in length. However, a few species reach lengths in excess of , and the green humphead parrotfish can reach up to . The smallest species is the Cryptotomus roseus, bluelip parrotfish (''Cryptotomus roseus''), which ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Queen Parrotfish
The queen parrotfish (''Scarus vetula'') 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". Description Adult queen parrotfishes are heavy-bodied fish with fusiform (spindle-shaped) bodies and beak-like mouths, growing to a length of about . They have two different color phases. Among smaller fish, the sexes are similar but nearly all individuals are female, being reddish-brown or grayish-brown with a paler head and a white lateral st ...

Coral Reef
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. Sometimes called ''rainforests of the sea'', shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fish, mollusks, worms, crustaceans, echinoderms, sp ...

Scarus
''Scarus'' is a genus of parrotfishes. With 52 currently recognised extant species,Froese, R. and D. Pauly, Eds''Scarus''.FishBase. 2013. 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 (males and females) and terminal (males only) phases. Adults of most species reach maximum lengths of between , but the rainbow parrotfish (''Scarus guacamaia'') can grow to lengths of . Species There are currently 52 recognised species in this genus: *'' Scarus altipinnis'' (Steindachner, 1879) (filament-finned parrotfish) *'' Scarus arabicus'' (Steindachner, 1902) (Arabian parrotfish) *'' Scarus caudofasciatus'' ( Günther, 1862) (red-barred parrotfish) *'' Scarus chameleon'' Choat & Randall, 1986 (c ...

Scarus Frenatus
''Scarus frenatus'' is a species of parrotfish. Common names include bridled parrotfish, sixband or six-banded parrotfish or vermiculate parrotfish. Description This species grows to a maximum length of 47 cm, and can be distinguished by its patterns and colouration. Its appearance changes during its life phases. During the initial phase, it has a reddish to brown colour, six to seven dark, horizontal stripes along its body, and red fins. In males, during the terminal phase, the posterior of the body and the lower half of the head appear abruptly lighter. Also, in males, the caudal fins appear blue-green with a large, orange, crescent-shaped area.

Wrasse
The wrasses are a family, Labridae, of marine fish, many of which are brightly colored. The family is large and diverse, with over 600 species in 81 genera, which are divided into 9 subgroups or tribes. They are typically small, most of them less than long, although the largest, the humphead wrasse, can measure up to . They are efficient carnivores, feeding on a wide range of small invertebrates. Many smaller wrasses follow the feeding trails of larger fish, picking up invertebrates disturbed by their passing. Juveniles of some representatives of the genera ''Bodianus'', ''Epibulus'', ''Cirrhilabrus'', ''Oxycheilinus'', and ''Paracheilinus'' hide among the tentacles of the free-living mushroom corals & ''Heliofungia actiniformis''. The word "wrasse" comes from the Cornish word ''wragh'', a lenited form of ''gwragh'', meaning an old woman or hag, via Cornish dialect ''wrath''. It is related to the Welsh ''gwrach'' and Breton ''gwrac'h''. Distribution Most wrasses inhabit the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Sparisoma
''Sparisoma'' is a genus of parrotfishes native to warmer parts of the Atlantic. FishBase recognizes 15 species in this genus, including ''S. rocha'' described from Trindade Island in 2010 and ''S. choati'' described from the East Atlantic in 2012.Rocha, Brito, and Robertson (2012). ''Sparisoma choati, a new species of Parrotfish (Labirdae: Scarinae) from the tropical eastern Atlantic''. Zootaxa, 3152: 61-67. They are the most important grazers of algae in the Caribbean Sea, especially since sea urchins, especially '' Diadema'', the other prominent consumers of algae, have been reduced in many places by a recent epidemic. The name was proposed by William John Swainson as a subgenus of '' Scarus''. ''Sparus'' in Latin is a golden-headed fish, and ''soma'' means "body". The common spelling ''Sparisomus'' is incorrect. The size of parrotfishes of this genus range from the rather small-sized ''S. radians'' with a known maximum length of to the large ''S. viride'', which reaches len ...

Bioerosion
Bioerosion describes the breakdown of hard ocean substrates – and less often terrestrial substrates – by living organisms. Marine bioerosion can be caused by mollusks, polychaete worms, phoronids, sponges, crustaceans, echinoids, and fish; it can occur on coastlines, on coral reefs, and on ships; its mechanisms include biotic boring, drilling, rasping, and scraping. On dry land, bioerosion is typically performed by pioneer plants or plant-like organisms such as lichen, and mostly chemical (e.g. by acidic secretions on limestone) or mechanical (e.g. by roots growing into cracks) in nature. Bioerosion of coral reefs generates the fine and white coral sand characteristic of tropical islands. The coral is converted to sand by internal bioeroders such as algae, fungi, bacteria (microborers) and sponges (Clionaidae), bivalves (including '' Lithophaga''), sipunculans, polychaetes, acrothoracican barnacles and phoronids, generating extremely fine sediment with diameters of 1 ...
