Tropiometra Carinata
The elegant feather star (''Tropiometra carinata'') is a species of crinoid in the family Tropiometridae. Description Elegant feather stars may grow to 20 cm in total length. They are variably coloured in yellow to brown and are occasionally variegated in yellow and brown. They have ten long arms with ciliated side branches that taper to a point. They have 20-30 cirri per arm.Branch, G.M., Branch, M.L, Griffiths, C.L. and Beckley, L.E. 2010. ''Two Oceans: a guide to the marine life of southern Africa'' Distribution These animals are found off the South African coast from the Cape Peninsula to Mozambique as well as circumtropically. They are seen subtidally and down to at least 51m underwater. Ecology Elegant feather stars are usually found singly on shallow reefs and are more abundant on deeper reefs. If displaced they may swim using their arms. Commensal organisms such as the myzostomid worm ''Myzostoma fuscomaculatum ''Myzostoma fuscomaculatum'', the crinoid worm, ...

Austin Clark
Austin Hobart Clark (December 17, 1880 – October 28, 1954) was an American zoologist. He was born in Wellesley, Massachusetts and died in Washington, D.C. His research covered a wide range of topics including oceanography, marine biology, ornithology, and entomology. Biography The son of Theodore Minot Clark and Jeannette French Clark, Clark obtained his Bachelor of Arts at Harvard University in 1903. He had five children with his first wife Mary Wendell Upham, whom he married on March 6, 1906. Mary died in December 1931 and Clark was remarried in 1933 to Leila Gay Forbes. In 1901, Clark organized a scientific expedition to Isla Margarita in Venezuela. From 1903 to 1905, he conducted research in the Antilles. From 1906 to 1907, he led a scientific team aboard the 1882 USS ''Albatross''. In 1908, he took a post at the National Museum of Natural History, which he held until his retirement in 1950. Clark had important and various roles in a number of learned so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Crinoid
Crinoids are marine animals that make up the class Crinoidea. Crinoids that are attached to the sea bottom by a stalk in their adult form are commonly called sea lilies, while the unstalked forms are called feather stars or comatulids, which are members of the largest crinoid order, Comatulida. Crinoids are echinoderms in the phylum Echinodermata, which also includes the starfish, brittle stars, sea urchins and sea cucumbers. They live in both shallow water and in depths as great as . Adult crinoids are characterised by having the mouth located on the upper surface. This is surrounded by feeding arms, and is linked to a U-shaped gut, with the anus being located on the oral disc near the mouth. Although the basic echinoderm pattern of fivefold symmetry can be recognised, in most crinoids the five arms are subdivided into ten or more. These have feathery pinnules and are spread wide to gather planktonic particles from the water. At some stage in their lives, most crinoids have ...

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda ...

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 opini ...
