Adamsia Sociabilis
''Adamsia'' is a genus of sea anemones in the family Hormathiidae. Species in this genus are mutually symbiotic with hermit crabs. The anemone gets a place to live and discarded scraps of the crab's food in exchange for its help in the crab's defence. As these anemones grow, they secrete a horny membrane, known as a carcinoecium, which overlies the crab's original snail shell and expands the living space of the crab. This means the anemone does not have to change substrate and the crab does not have to seek a larger shell as they both grow. Species Species within the genus include: * ''Adamsia fusca'' (Quoy & Gaimard, 1833) * ''Adamsia involvens'' McMurrich, 1893 * ''Adamsia obvolva'' Daly et al., 2004 * ''Adamsia palliata'' (Fabricius, 1779) * ''Adamsia rondeletti ''Adamsia'' is a genus of sea anemones in the family Hormathiidae.

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 ...

Sea Anemones
Sea anemones are a group of predatory marine invertebrates of the order Actiniaria. Because of their colourful appearance, they are named after the ''Anemone'', a terrestrial flowering plant. Sea anemones are classified in the phylum Cnidaria, class Anthozoa, subclass Hexacorallia. As cnidarians, sea anemones are related to corals, jellyfish, tube-dwelling anemones, and '' Hydra''. Unlike jellyfish, sea anemones do not have a medusa stage in their life cycle. A typical sea anemone is a single polyp attached to a hard surface by its base, but some species live in soft sediment, and a few float near the surface of the water. The polyp has a columnar trunk topped by an oral disc with a ring of tentacles and a central mouth. The tentacles can be retracted inside the body cavity or expanded to catch passing prey. They are armed with cnidocytes (stinging cells). In many species, additional nourishment comes from a symbiotic relationship with single-celled dinoflagellates, with zooxa ...

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 ...

Symbiosis
Symbiosis (from Greek , , "living together", from , , "together", and , bíōsis, "living") is any type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasitic. The organisms, each termed a symbiont, must be of different species. In 1879, Heinrich Anton de Bary defined it as "the living together of unlike organisms". The term was subject to a century-long debate about whether it should specifically denote mutualism, as in lichens. Biologists have now abandoned that restriction. Symbiosis can be obligatory, which means that one or more of the symbionts depend on each other for survival, or facultative (optional), when they can generally live independently. Symbiosis is also classified by physical attachment. When symbionts form a single body it is called conjunctive symbiosis, while all other arrangements are called disjunctive symbiosis."symbiosis."

Adamsia Fusca
''Adamsia'' is a genus of sea anemones in the family Hormathiidae. Species in this genus are mutually symbiotic with hermit crabs. The anemone gets a place to live and discarded scraps of the crab's food in exchange for its help in the crab's defence. As these anemones grow, they secrete a horny membrane, known as a carcinoecium, which overlies the crab's original snail shell and expands the living space of the crab. This means the anemone does not have to change substrate and the crab does not have to seek a larger shell as they both grow. Species Species within the genus include: * '' Adamsia fusca'' (Quoy & Gaimard, 1833) * ''Adamsia involvens'' McMurrich, 1893 * '' Adamsia obvolva'' Daly et al., 2004 * ''Adamsia palliata ''Adamsia palliata'' is a species of sea anemone in the family Hormathiidae.

Adamsia Palliata
''Adamsia palliata'' is a species of sea anemone in the family Hormathiidae. It is usually found growing on a gastropod shell inhabited by the hermit crab, '' Pagurus prideaux''. The anemone often completely envelops the shell and because of this it is commonly known as the cloak anemone or the hermit-crab anemone. Taxonomy In a revision of British Anthozoa in 1981, Manuel applied the name ''Adamsia carciniopados'' to this species, attributing it to Otto, 1823. However Cornelius and Ates in 2003 decided that ''Adamsia palliata'' was the valid name, attributing it to O.F. Muller, 1776. Description ''A. palliata'' normally lives on the shell of a sea snail which is housing a hermit crab. The anemone's base is wide and convoluted with lobes that extend around the shell. The edges join together in a suture where the shell is completely encircled. The oral disc and tentacles are orientated downwards beneath the underside of the crab. The basal lobes can extend to about fifteen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
