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 ...

Sparisoma Chrysopterum
''Sparisoma chrysopterum'' (common names: redtail parrotfish, blue parrotfish, kwab, pink kwab, pink parrot, blisterside, and blue black-finned chub) is a species of parrotfish. Description The upper end of the pectoral fin base shows black saddle-shaped markings while they are young adults. Commonly, there is a light, saddle-shaped area on top of caudal peduncle. The dorsal, pelvic, and anal fins are orange or red in colour. Juvenile specimens or those in the initial phase have a mottled pattern similar to the substratum. This provides camouflage when they rest on the sea floor. Distribution This species lives in the western Atlantic Ocean from Brazil in the south, north to Florida and the Bahamas. It also occurs throughout the Caribbean Sea. Diet ''Sparisoma chrysopterum'' This species grazes on seagrasses and algae growing in the benthic zone. Parasites This species is known to host an ectoparasite in the genus ''Caligus'' named ''Caligus atromaculatus'' (C.B. Wilson, 191 ...

Sparisoma Viride
The stoplight parrotfish (''Sparisoma viride'') is a species of marine ray-finned fish, a parrotfish from the Family (biology), family Scaridae, inhabiting coral reefs in Florida, Caribbean Sea, Gulf of Mexico, Bermuda and as far south as Brazil. It mainly feeds on algae by scraping and excavating it with its teeth. Like most of its relatives, it is able to Sequential hermaphroditism#Protogyny, change sex. The common name, stoplight, comes from the marked yellow spot near the pectoral fin, which is clearly visible only in specimens in the terminal phase. Sex Change & Coloring The stoplight parrotfish is a Sequential hermaphroditism#Protogyny, protogynous hermaphrodite that shows full sexual dichromatism, meaning that it changes its sex from female to male during its lifespan, and its color changes with its sex change. The sex change is most likely due to the control of hormones, in particular, 11-Ketotestosterone, 11-ketetestosterone (11-KT). The timing of the sex change can va ...

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] |
Felipe Poey
Felipe Poey (May 26, 1799 – January 28, 1891) was a Cuban zoologist. Biography Poey was born in Havana, the son of French and Spanish parents. He spent several years (1804 to 1807) of his life in Pau then studied law in Madrid. He became a lawyer in Spain but was forced to leave due to his liberal ideas, returning to Cuba in 1823. He began to concentrate on the study of the natural science and traveled to France in 1825 with his wife. He began writing on the butterflies of Cuba and acquiring knowledge on fish, later supplying Georges Cuvier and Valenciennes with fish specimens from Cuba. He took part in the foundation, in 1832, of the Société Entomologique de France. Poey returned to Cuba in 1833 where he founded the Museum of Natural History in 1839. In 1842 he became the first professor of zoology and comparative anatomy at the University of Havana The University of Havana or (UH, ''Universidad de La Habana'') is a university located in the Vedado district of Hava ...

Sequential Hermaphrodite
Sequential hermaphroditism (called dichogamy in botany) is a type of hermaphroditism that occurs in many fish, gastropods, and plants. Sequential hermaphroditism occurs when the individual changes its sex at some point in its life. In particular, a sequential hermaphrodite produces eggs (female gametes) and sperm (male gametes) at different stages in life. Species that can undergo these changes from one sex to another do so as a normal event within their reproductive cycle that is usually cued by either social structure or the achievement of a certain age or size. In animals, the different types of change are male to female (protandry or protandrous hermaphroditism), female to male (protogyny or protogynous hermaphroditism), bidirectional (serial or bidirectional hermaphroditism). Both protogynous and protandrous hermaphroditism allow the organism to switch between functional male and functional female. Bidirectional hermaphrodites have the capacity for sex change in either directi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Achille Valenciennes
Achille Valenciennes (9 August 1794 – 13 April 1865) was a French zoologist. Valenciennes was born in Paris, and studied under Georges Cuvier. His study of parasitic worms in humans made an important contribution to the study of parasitology. He also carried out diverse systematic classifications, linking fossil and current species. He worked with Cuvier on the 22-volume "'' Histoire Naturelle des Poissons''" (Natural History of Fish) (1828–1848), carrying on alone after Cuvier died in 1832. In 1832, he succeeded Henri Marie Ducrotay de Blainville (1777–1850) as chair of ''Histoire naturelle des mollusques, des vers et des zoophytes'' at the Muséum national d'histoire naturelle. Early in his career, he was given the task of classifying animals described by Alexander von Humboldt (1769–1859) during his travels in the American tropics (1799 to 1803), and a lasting friendship was established between the two men. He is the binomial authority for many species of fish, such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coral
Corals are marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically form compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. A coral "group" is a colony of very many genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in height. A set of tentacles surround a central mouth opening. Each polyp excretes an exoskeleton near the base. Over many generations, the colony thus creates a skeleton characteristic of the species which can measure up to several meters in size. Individual colonies grow by asexual reproduction of polyps. Corals also breed sexually by spawning: polyps of the same species release gametes simultaneously overnight, often around a full moon. Fertilized eggs form planulae, a mobile early form of the coral polyp which, when m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
