Radianthus Doreensis
''Radianthus doreensis'', also known as long tentacle anemone and corkscrew tentacle sea anemone, is a species of sea anemone in the family (biology), family Stichodactylidae. Description ''Radianthus doreensis'' has relatively few tentacles. They are all similar to one another in size and colour, being purplish-gray to brown. Each grows to about 1.75 inches, are sinuous, and each taper evenly toward the tip. In some cases they have a corkscrew shape. The oral disc is normally purplish-gray to brown, and sometimes has a green cast. It has a flared shape, and grows to a maximum of 5 cm wide, but is often far smaller. It has white lines that are oriented radially, sometimes extending onto the tentacles. This species remains at the surface of the sediment, with the column buried. The lower portion of the column is a dull orange to bright red colour, with the upper portion being brownish, containing a round to ovoid verrucae in rows oriented longitudinally. Distribution ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphiprion Ocellaris
The ocellaris clownfish (''Amphiprion ocellaris''), also known as the false percula clownfish or common clownfish, is a marine fish belonging to the family Pomacentridae, which includes clownfishes and damselfishes. ''Amphiprion ocellaris'' are found in different colors, depending on where they are located. For example, black ''Amphiprion ocellaris'' with white bands can be found near northern Hawaii, USA, North America, Australia, Southeast Asia, and Japan. Orange or red-brown ''Amphiprion ocellaris ''also exist with three similar white bands on the body and head. ''Amphiprion ocellaris ''can be distinguished from other ''Amphiprion'' species based on the number of pectoral rays and dorsal spines. ''Amphiprion ocellaris ''are known to grow about 11 cm (4.3 inches) long. Like many other fish species, females are, however, larger than males. The life cycle of ''Amphiprion ocellaris ''varies in whether they reside at the surface or bottom of the ocean. When they initially hatch, ...

Taxa Named By Jean René Constant Quoy
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animals Described In 1833
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia (). With few exceptions, animals consume organic material, breathe oxygen, have myocytes and are able to move, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million living animal species have been described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth. Animal body lengths range from to . They have complex ecologies and interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology, and the study of animal behaviour is known as ethology. The animal kingdom is divided into five major clades, namely Porifera, Ctenopho ...

Actiniidae
Actiniidae is the largest family (biology), family of sea anemones, to which most common, temperate, shore species belong. Most members of this family do not participate in symbiosis, symbioses with fishes. Three exceptions are the bubble-tip anemone (with anemonefish and certain cardinalfish), snakelocks anemone (with Incognito goby) and ''Urticina piscivora'' (with painted greenling). The systematics of Actiniidae is often quite difficult. The problem with identification of genera within this family is that most species are readily distinguishable when alive but when fixation (histology), fixated lose their color and some other features. Arrangement of tentacles is important in defining genera for Actiniaria families. There may be one tentacle per space between Mesentery (zoology), mesenteries or there may be more than one tentacle between each two mesenteries. Members of the family Actiniidae have one tentacle per space. Genera There are over 300 recognized species in 57 gene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Australian Museum
The Western Australian Museum is a statutory body, statutory authority within the Culture and the Arts Portfolio, established under the ''Museum Act 1969''. The museum has six main sites. The state museum, WA Museum Boola Bardip, is located in the Perth Cultural Centre. The other sites are: the WA Maritime Museum and WA Shipwrecks Museum in Fremantle (suburb), Fremantle, the Museum of the Great Southern in Albany, Western Australia, Albany, the Museum of Geraldton in Geraldton, and the Museum of the Goldfields in Kalgoorlie, Kalgoorlie-Boulder. History Established in 1891 in the Perth Gaol, Old Perth Gaol, it was known as the Geological Museum and consisted of geological collections. In 1892, ethnological and biological exhibits were added, and in 1897, the museum officially became the Western Australian Museum and Art Gallery. The museum employed collectors to obtain series of specimens; J. T. Tunney, Tunney ventured across the state from 1895 to 1909 obtaining animals and ...

Dascyllus Trimaculatus
The threespot dascyllus (''Dascyllus trimaculatus''), also known as the domino damsel or simply domino, is a species of damselfish from the family Pomacentridae. It is native to the Indo-Pacific from the Red Sea and East Africa, to the Pitcairn Islands, southern Japan, and Australia, and can also be found in some parts of the Philippines. Taxonomy ''Dascyllus trimaculatus'' is one of four species in its namesake ''D. trimaculatus'' species complex. The other three species in this complex are '' D. albisella'', '' D. strasburgi'', and '' D. auripinnis''. ''D. trimaculatus'' and ''D. auripinnis'' are parapatric (their ranges overlap in the Northern Cook Islands), but the four species are otherwise all allopatric. The ''D. trimaculatus'' complex diverged from the ''D. reticulatus'' complex 3.9 million years ago, in the Pleistocene. Mitochondrial genome analysis found that ''D. trimaculatus'' itself can be split into three populations: Indian Ocean, southern French Polynesia, and ...

Amphiprion Perideraion
The pink skunk clownfish (''Amphiprion perideraion''), also known as the pink anemonefish, is a species of anemonefish that is widespread from northern Australia through the Malay Archipelago and Melanesia. Like all anemonefishes, it forms a symbiotic mutualism with sea anemones and is unaffected by the stinging tentacles of the host. It is a sequential hermaphrodite with a strict size-based dominance hierarchy; the female is largest, the breeding male is second largest, and the male nonbreeders get progressively smaller as the hierarchy descends. They exhibit protandry, meaning the breeding male changes to female if the sole breeding female dies, with the largest nonbreeder becoming the breeding male. Description The body of ''A. perideraion'' is pink to peach. It has the white stripe along the dorsal ridge that is common to all members of the skunk complex and a white head bar running vertically just behind the eye. While the largest species of anemonefish can reach a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphiprion Clarkii
Clark's anemonefish (''Amphiprion clarkii''), also known as the yellowtail clownfish, is a marine fish belonging to the family Pomacentridae, the clownfishes and damselfishes. 28 species of anemonefish live within the Pomacentridae family (Steer P. 2012). Characteristics of anemonefish Clownfish or anemonefish are fishes that, in the wild, form symbiotic mutualisms with sea anemones and are unaffected by the stinging tentacles of the host anemone, see . The sea anemone protects the clownfish from predators, as well as providing food through the scraps left from the anemone's meals and occasional dead anemone tentacles. In return, the clownfish defends the anemone from its predators, and parasites. Anemonefish tend to have a life span of about 10-11 years when accounting for a predictable environment that does not experience much change in water temperature, increase in predation or habitat degradation (Lakshmi Sawitri). Clownfish are small-sized, , and depending on species, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Anemone
Sea anemones ( ) are a group of predation, predatory marine invertebrates constituting the order (biology), 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 (genus), Hydra''. Unlike jellyfish, sea anemones do not have a Jellyfish#Life history and behavior, medusa stage in their life cycle. A typical sea anemone is a single polyp (zoology), 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 specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphiprion Chrysopterus
The orange-fin anemonefish (''Amphiprion chrysopterus'') is a marine fish belonging to the family Pomacentridae, the clownfishes and damselfishes, found in the Western Pacific north of the Great Barrier Reef from the surface to 20 m, to include the Pacific Ocean between Queensland, Australia, and New Guinea to the Marshall and Tuamotus Islands. It can grow to 17 cm in length. Characteristics of anemonefish Clownfish or anemonefish are fishes, that in the wild, form symbiotic mutualisms with sea anemones and are unaffected by the stinging tentacles of the host anemone, see . The sea anemone protects the clownfish from predators, as well as providing food through the scraps left from the anemone's meals and occasional dead anemone tentacles. In return, the clownfish defends the anemone from its predators and parasites.

Amphiprion Chrysogaster
''Amphiprion chrysogaster'', the Mauritian anemonefish, is a marine fish belonging to the family Pomacentridae, the clownfishes and damselfishes. It is endemic to Mauritius and probably Réunion. Characteristics of Anemonefish Clownfish or anemonefish are fishes that, in the wild, form symbiotic mutualisms with sea anemones and are unaffected by the stinging tentacles of the host anemone, see . The sea anemone protects the clownfish from predators, as well as providing food through the scraps left from the anemone's meals and occasional dead anemone tentacles. In return, the clownfish defends the anemone from its predators, and parasites. Clownfish are small-sized, , and depending on species, they are overall yellow, orange, or a reddish or blackish color, and many show white bars or patches. Within species there may be color variations, most commonly according to distribution, but also based on sex, age and host anemone. Clownfish are found in warmer waters of the Indian ...
