Cape Seahorse
The Knysna seahorse or Cape seahorse (''Hippocampus capensis'') is a species of fish in the family Syngnathidae. It is Endemism, endemic to the south coast of South Africa, where it has been found in only three brackish water habitats: the estuary of the Keurbooms River in Plettenberg Bay, the Knysna Lagoon, and the estuarine portion of the Swartvlei, Western Cape, Swartvlei system in Sedgefield, Western Cape, Sedgefield. The limited range of this seahorse puts it at great risk of extinction. Description The Knysna seahorse is a small, delicate creature with a standard length of up to 12 centimetres. Colouration is strongly influenced by the surrounding environment and a particular individual's mood. It varies from pale green to brown (often with darker speckles) to purplish black. The body is encased in a series of bony rings, the snout is relatively short, and the neck arches in a smooth curve without a crown. The tail is muscular and is used to grasp a mate during courtship ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes. He graduated in 1876 from the Free University of Brussels (1834–1969), Free University of Brussels with a degree in natural sciences, and worked for a while at the Royal Belgian Institute of Natural Sciences, Brussels, as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the ''National Museum of Natural History (France), Muséum national d'Histoire naturelle'' in Paris and the Natural History Museum, London, British Museum in London.

Coronet
In British heraldry, a coronet is a type of crown that is a mark of rank of non-reigning members of the royal family and peers. In other languages, this distinction is not made, and usually the same word for ''crown'' is used irrespective of rank (, , , , , etc.) In this use, the English ''coronet'' is a purely technical term for all heraldic images of crowns not used by a sovereign. A Coronet is another type of crown, but is reserved for the nobility - Dukes, Marquesses, Earls, Viscounts and Barons. The specific design and attributes of the crown or coronet signifies the hierarchy and ranking of its owner. Certain physical coronets are worn by the British peerage on rare ceremonial occasions, such as the coronation of the monarch. These are also sometimes depicted in heraldry, and called coronets of rank in heraldic usage. Their shape varies depending on the wearer's rank in the peerage, according to models laid down in the 16th century. Similar depictions of crowns of rank () ...

Hippocampus Kuda
''Hippocampus kuda'' is a species of seahorse, also known as the common seahorse, estuary seahorse, yellow seahorse or spotted seahorse. The common name sea pony has been used for populations formerly treated as the separate species ''Hippocampus fuscus'', now a synonym of ''H. kuda''. Physical description The yellow seahorse is a small fish that can reach a length of 17–30 cm. The body is quite large, elongated, and has no spines, all bumps are rounded. The head is relatively large compared to the body. The snout is short and thick. The coronet is small and rises towards the rear, it can also sometimes have more or less long filaments. Some adults have a black line running through the dorsal fin in the direction of its width. The body coloration is often dark with a grainy texture but can also be yellow, cream, or reddish blotches and numerous small dark spots. The seahorse possesses a tail that is used as a bending and grasping appendage. The seahorse is able to bend ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indo-Pacific
The Indo-Pacific is a vast biogeographic region of Earth. In a narrow sense, sometimes known as the Indo-West Pacific or Indo-Pacific Asia, it comprises the tropical waters of the Indian Ocean, the western and central Pacific Ocean, and the seas connecting the two. The term is especially useful in marine biology, ichthyology, and similar fields, since many marine habitats are continuously connected from Madagascar to Japan and Oceania, and a number of species occur over that range, but are not found in the Atlantic Ocean. As a distinct marine realm, the region has an exceptionally high species richness, with the world's highest species richness being found in at its heart in the Coral Triangle, and a remarkable gradient of decreasing species richness radiating outward in all directions. The region includes over 3,000 species of fish, compared with around 1,200 in the next richest marine region, the Western Atlantic, and around 500 species of reef building corals, compar ...

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or approximately 20% of the water area of Earth#Surface, Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia (continent), Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. The Indian Ocean has large marginal or regional seas, including the Andaman Sea, the Arabian Sea, the Bay of Bengal, and the Laccadive Sea. Geologically, the Indian Ocean is the youngest of the oceans, and it has distinct features such as narrow continental shelf, continental shelves. Its average depth is 3,741 m. It is the warmest ocean, with a significant impact on global climate due to its interaction with the atmosphere. Its waters are affected by the Indian Ocean Walker circulation, resulting in unique oceanic currents and upwelling patterns. The Indian Ocean is ecologically diverse, with important ecosystems such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Microsatellite
A microsatellite is a tract of repetitive DNA in which certain Sequence motif, DNA motifs (ranging in length from one to six or more base pairs) are repeated, typically 5–50 times. Microsatellites occur at thousands of locations within an organism's genome. They have a higher mutation rate than other areas of DNA leading to high genetic diversity. Microsatellites are often referred to as short tandem repeats (STRs) by forensic genetics, forensic geneticists and in genetic genealogy, or as simple sequence repeats (SSRs) by plant geneticists. Microsatellites and their longer cousins, the minisatellites, together are classified as variable number tandem repeat, VNTR (variable number of tandem repeats) DNA. The name Satellite DNA, "satellite" DNA refers to the early observation that centrifugation of genomic DNA in a test tube separates a prominent layer of bulk DNA from accompanying "satellite" layers of repetitive DNA. They are widely used for DNA profiling in Loss of heterozygos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Ecology
Molecular ecology is a subdiscipline of ecology that is concerned with applying Molecular genetics, molecular genetic techniques to ecological questions (e.g., population structure, phylogeography, conservation, speciation, hybridization, biodiversity). It is virtually synonymous with the field of "Ecological genetics, Ecological Genetics" as pioneered by Theodosius Dobzhansky, E. B. Ford, Godfrey Hewitt, Godfrey M. Hewitt, and others. Molecular ecology is related to the fields of population genetics and conservation genetics. Methods frequently include using Microsatellite (genetics), microsatellites to determine gene flow and Hybrid (biology), hybridization between populations. The development of molecular ecology is also closely related to the use of microarray, DNA microarrays, which allows for the simultaneous analysis of the expression of thousands of different genes. Quantitative PCR may also be used to analyze gene expression as a result of changes in environmental conditi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...
