Diploastrea
''Diploastrea'' is a genus of corals. It is the only genus in the monotypic family Family (from la, familia) is a group of people related either by consanguinity (by recognized birth) or affinity (by marriage or other relationship). The purpose of the family is to maintain the well-being of its members and of society. Idea ... Diploastreidae.

Diploastrea Heliopora
''Diploastrea heliopora'', commonly known as diploastrea brain coral or honeycomb coral among other vernacular names, is a species of hard coral in the family Diploastreidae. It is the only extant species in its genus. This species can form massive dome-shaped colonies of great size. Taxonomy ''Diploastrea heliopora'' was first described in 1816 by the French naturalist Jean-Baptiste Lamarck as ''Astrea heliopora''. It was transferred to the new genus ''Diploastrea'' by G. Matthai in 1914. ''Diploastrea heliopora'' was included in the family Agathiphylliidae by T.W. Vaughan and J.W. Wells in 1943. It was the only extant member of the family, which also included four fossil species. In 1956, Wells transferred the genus to Faviidae, and this has been widely accepted. However, recent molecular and phylogenetic studies show that this coral has certain unique features, and a separate family, Diploastreidae, has been reinstated. It is the only extant member of the family. Description ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

George Matthai
George Matthai (13 November 1887 – 22 June 1947) was an Indian zoologist who specialized in marine biology, contributing to the systematics of Madreporarian (now Scleractinia) corals. He was a professor of zoology at the Panjab University in Lahore. Life and career He returned to India in 1918 and worked at the department of zoology at the Panjab University, Lahore. He received a ScD from the University of Cambridge in 1929. He succeeded Lt. Col. J. Stephenson in 1919 and his retirement in 1942 was postponed to 1945 due to the war. Matthai married Mary Chandy, daughter of C. Chandy of the Mysore Civil Service and later vice chancellor of Mysore University, in 1925. They had a son, Ariel, and after her death in 1931, Matthai married Rosalinda Hedwig in 1935. Matthai was elected Fellow of the Zoological Society of London The Zoological Society of London (ZSL) is a charity devoted to the worldwide conservation of animals and their habitats. It was founded in 1826. Since ... [...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, whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opin ...

Scleractinia Genera
Scleractinia, also called stony corals or hard corals, are marine animals in the phylum Cnidaria that build themselves a hard skeleton. The individual animals are known as polyps and have a cylindrical body crowned by an oral disc in which a mouth is fringed with tentacles. Although some species are solitary, most are colonial. The founding polyp settles and starts to secrete calcium carbonate to protect its soft body. Solitary corals can be as much as across but in colonial species the polyps are usually only a few millimetres in diameter. These polyps reproduce asexually by budding, but remain attached to each other, forming a multi-polyp colony of clones with a common skeleton, which may be up to several metres in diameter or height according to species. The shape and appearance of each coral colony depends not only on the species, but also on its location, depth, the amount of water movement and other factors. Many shallow-water corals contain symbiont unicellular organ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
