Bluestriped Grunt
The bluestriped grunt (''Haemulon sciurus''), also known as the boar grunt, golden grunt, humpback grunt, redmouth grunt, or yellow grunt, is a species of marine ray-finned fish, a grunt belonging to the family Haemulidae. It is found in the western Atlantic Ocean. Description The bluestriped grunt has a deep, almond-shaped body with a moderately convex dorsal profile. Its upper jaw extends to underneath the centre of the eye. The scales above the lateral line are enlarged, whereas those underneath it are arranged in a diagonal pattern. It has a continuous dorsal fin with a small to medium-sized notch in its centre. The dorsal fin contains 12 spines and 16-17 soft rays, while the anal fin contains 3 spines and 9 soft rays. The overall colour of this species’ head and body is yellow broken by thin, longitudinal blue stripes. Also, a distinctively arched stripe occurs below each eye. The spiny part of the dorsal fin is yellow, the soft-rayed part of the dorsal fin and the caudal fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Shaw (biologist)
George Kearsley Shaw (10 December 1751 – 22 July 1813) was an English botanist and zoologist. Life Shaw was born at Bierton, Buckinghamshire, and was educated at Magdalen Hall, Oxford, receiving his M.A. in 1772. He took up the profession of medical practitioner. In 1786, he became the assistant lecturer in botany at the University of Oxford. He became a fellow of the Royal Society in 1789. In 1791, Shaw became assistant keeper of the natural history department at the British Museum, succeeding Edward Whitaker Gray as keeper in 1806. He found that most of the items donated to the museum by Hans Sloane were in very bad condition. Medical and anatomical material was sent to the museum at the Royal College of Surgeons of England, Royal College of Surgeons, but many of the stuffed animals and birds had deteriorated and had to be burnt. He was succeeded after his death by his assistant Charles Konig. Shaw's library of natural history books and some of his specimens and equipment ...

Caribbean Sea
The Caribbean Sea is a sea of the Atlantic Ocean, North Atlantic Ocean in the tropics of the Western Hemisphere, located south of the Gulf of Mexico and southwest of the Sargasso Sea. It is bounded by the Greater Antilles to the north from Cuba to Puerto Rico, the Lesser Antilles to the east from the Virgin Islands to Trinidad and Tobago, South America to the south from the Venezuela, Venezuelan coastline to the Colombia, Colombian coastline, and Central America and the Yucatán Peninsula to the west from Panama to Mexico. The Geopolitics, geopolitical region around the Caribbean Sea, including the numerous islands of the West Indies and adjacent coastal areas in the mainland of the Americas, is known as the Caribbean. The Caribbean Sea is one of the largest seas on Earth and has an area of about . The sea's deepest point is the Cayman Trough, between the Cayman Islands and Jamaica, at below sea level. The Caribbean coastline has many gulfs and bays: the Gulf of Gonâve, the Gul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antilles
The Antilles is an archipelago bordered by the Caribbean Sea to the south and west, the Gulf of Mexico to the northwest, and the Atlantic Ocean to the north and east. The Antillean islands are divided into two smaller groupings: the Greater Antilles and the Lesser Antilles. The Greater Antilles includes the Cayman Islands and larger islands of Cuba, Hispaniola (subdivided into the nations of the Dominican Republic and Haiti) and Navassa Island, Jamaica, and Puerto Rico. The Lesser Antilles contains the northerly Leeward Islands and the southeasterly Windward Islands as well as the Leeward Antilles just north of Venezuela. The Lucayan Archipelago (consisting of The Bahamas and the Turks and Caicos Islands), though a part of the West Indies, is generally not included among the Antillean islands. Geography, Geographically, the Antillean islands are generally considered a subregion of North America. Culturally speaking, Cuba, the Dominican Republic, and Puerto Rico – and sometime ...

Type Locality (biology)
In biology, a type is a particular wikt:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the ...

Zoologist
Zoology ( , ) is the scientific study of animals. Its studies include the structure, embryology, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems. Zoology is one of the primary branches of biology. The term is derived from Ancient Greek , ('animal'), and , ('knowledge', 'study'). Although humans have always been interested in the natural history of the animals they saw around them, and used this knowledge to domesticate certain species, the formal study of zoology can be said to have originated with Aristotle. He viewed animals as living organisms, studied their structure and development, and considered their adaptations to their surroundings and the function of their parts. Modern zoology has its origins during the Renaissance and early modern period, with Carl Linnaeus, Antonie van Leeuwenhoek, Robert Hooke, Charles Darwin, Gregor Mendel and many others. The study of animals has largely mov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
English People
The English people are an ethnic group and nation native to England, who speak the English language in England, English language, a West Germanic languages, West Germanic language, and share a common ancestry, history, and culture. The English identity began with the History of Anglo-Saxon England, Anglo-Saxons, when they were known as the , meaning "Angle kin" or "English people". Their ethnonym is derived from the Angles (tribe), Angles, one of the Germanic peoples who invaded Great Britain, Britain around the 5th century AD. The English largely descend from two main historical population groups: the West Germanic tribes, including the Angles, Saxons, and Jutes who settled in England and Wales, Southern Britain following the withdrawal of the Ancient Rome, Romans, and the Romano-British culture, partially Romanised Celtic Britons who already lived there.Martiniano, R., Caffell, A., Holst, M. et al.

Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Encotyllabe Spari
Capsalidae Yamaguti, S. (1963) Systema Helminthum IV. Monogenea and Aspidocotylea. London-New York, Interscience Publishers. 699 pp. is a family of monopisthocotylean monogeneans, which includes about 200 species. The monophyly of the Capsalidae is supported by possession of accessory sclerites in the haptor (the posterior attachment organ), and was confirmed by molecular phylogeny. Their oncomiracidium (the free larva) is distinct from that of other families. Capsalids are parasite on various organs of marine fish (teleosts and elasmobranchs), including skin, fins and gills. Several capsalid species, such a ''Neobenedenia'' spp. are pathogenic, especially on maricultured fish. Included genera Genera as recognized iWorMsare listed below. Recent molecular analyses have shown that several genera, which were defined on morphological characters, are not monophyletic. ''Menziesia'' and ''Nitzschia'' have their equivalent in the botanical nomenclature: ''Menziesia'' (a flowering p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monogenea
Monogeneans, members of the class Monogenea, are a group of ectoparasitic flatworms commonly found on the skin, gills, or fins of fish. They have a direct lifecycle and do not require an intermediate host. Adults are hermaphrodites, meaning they have both male and female reproductive structures.L.A. Tubbsa et al. (2005). "Effects of temperature on fecundity in vitro, egg hatching and reproductive development of ''Benedenia seriolae'' and ''Zeuxapta seriolae'' (Monogenea) parasitic on yellowtail kingfish Seriola lalandi". ''International Journal for Parasitology''(35), 315–327. Some monogeneans are oviparous (egg-laying) and some are viviparous (live-bearing). Oviparous varieties release eggs into the water. Viviparous varieties release larvae, which immediately attach to another host. The genus ''Gyrodactylus'' is an example of a viviparous variety, while the genus ''Dactylogyrus'' is an example of an oviparous variety. Signs and symptoms Freshwater fish that become infect ...

Parasites
Parasitism is a close relationship between species, where one organism, the parasite, lives (at least some of the time) on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson characterised parasites' way of feeding as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes. There are six major parasitic strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), trophicallytransmitted parasitism (by being eaten), vector-transmitted parasitism, parasitoidism, and micropredation. One major axis of classification concerns invasiveness: an endo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spawn (biology)
Spawn is the eggs and sperm released or deposited into water by aquatic animals. As a verb, ''to spawn'' refers to the process of freely releasing eggs and sperm into a body of water (fresh or marine); the physical act is known as spawning. The vast majority of aquatic and amphibious animals reproduce through spawning. These include the following groups: * Bony fishes * Crustaceans (such as crabs, shrimps, etc.) *Mollusks (such as oysters, octopus, squid) *Echinoderms (such as sea urchins, sea stars, sea cucumbers, etc.) * Amphibians (such as frogs, toads, salamanders, newts) * Aquatic insects (such as dragonflies, mayflies, mosquitoes) *Coral, which are living colonies of tiny, aquatic organisms—not plants, as they are sometimes perceived to be. Corals, while appearing sedentary or botanical by nature, actually spawn by releasing clouds of sperm and egg cells into the water column, where the two mix. As a general rule, aquatic or semiaquatic reptiles, birds, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thalassia Testudinum
''Thalassia testudinum'', commonly known as turtlegrass, is a species of Marine (ocean), marine seagrass in the family Hydrocharitaceae. It forms meadows in shallow sandy or muddy locations in the Caribbean Sea and the Gulf of Mexico. Turtle grass and other seagrasses form seagrass meadow, meadows which are important habitats and feeding grounds. The grass is eaten by turtles and herbivorous fish, supports many epiphytes, and provides habitat for juvenile fish and many invertebrate taxa. Description ''Thalassia testudinum'' is a perennial grass growing from a long, jointed rhizome. The rhizome is buried in the Substrate (biology), substrate deep, exceptionally down to . Some nodes are leafless but others bear a tuft of several erect, linear leaf blades. These are up to long and wide and have rounded tips. The flowers grow on short stalks in the axils of the leaves and are greenish-white, sometimes tinged pink, and are followed by seed pods. Distribution and habitat Turtle ...
