Atelecrinidae
Atelecrinidae is a family of crinoids or feather stars in the phylum Echinodermata. It was first described by Francis Arthur Bather Francis Arthur Bather FRS (17 February 1863, in Richmond upon Thames – 20 March 1934) was a British palaeontologist, geologist and malacologist.

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 ...

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 ...

Echinodermata
An echinoderm () is any member of the phylum Echinodermata (). The adults are recognisable by their (usually five-point) radial symmetry, and include starfish, brittle stars, sea urchins, sand dollars, and sea cucumbers, as well as the sea lilies or "stone lilies". Adult echinoderms are found on the sea bed at every ocean depth, from the intertidal zone to the abyssal zone. The phylum contains about 7,000 living species, making it the second-largest grouping of deuterostomes, after the chordates. Echinoderms are the largest entirely marine phylum. The first definitive echinoderms appeared near the start of the Cambrian. The echinoderms are important both ecologically and geologically. Ecologically, there are few other groupings so abundant in the biotic desert of the deep sea, as well as shallower oceans. Most echinoderms are able to reproduce asexually and regenerate tissue, organs, and limbs; in some cases, they can undergo complete regeneration from a single limb. Geolo ...

Francis Arthur Bather
Francis Arthur Bather FRS (17 February 1863, in Richmond upon Thames – 20 March 1934) was a British palaeontologist, geologist and malacologist. His mother, Lucy Elizabeth Blomfield, was a daughter of Charles Blomfield, Bishop of London. His father, Arthur Henry Bather, who was deaf, was a clerk in the office of the Accountant-General for the Navy. Bather joined the Department of Geology at the Natural History Museum in 1887. He became Keeper in succession to Arthur Smith Woodward in 1924, retiring in 1928. Bather was awarded the Lyell Medal of the Geological Society, of which he also served as president. He was an Honorary Member of the Royal Geological Society of Cornwall, and was elected a fellow of the Royal Society in 1909. He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1928. In 1932 Bather was awarded the Mary Clark Thompson Medal from the National Academy of Sciences. He married Stina Bergöö, daughter of Adolf Bergöö of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
