Heteractis Aurora
''Heteractis aurora'' is a species of sea anemone in the family Stichodactylidae. Taxonomy Common names for ''H. aurora'' include beaded sea anemone, aurora host anemone, sand anemone, carpet anemone, flat anemone, corn anemone, Ritteri anemone, saddle tip anemone, adhesive sea anemone, and the white beaded anemone. Description Both the tentacles and oral disc of ''H. aurora'' are brown or purplish. The tentacles reach 50 mm in length, may be sticky when touched, and can have tips of a magenta colouration. The longer tentacles contain swellings. These appear on only on a single side, or almost entirely surrounding the tentacle, giving the appearance of beads on a string. A maximum of 20 such swellings may occur on any single tentacle. This species has a broad, flattened oral disc reaching 250 mm wide, and may have white or brown markings that radiate from the centre, and even continue up and along the tentacles. Distribution and habitat ''H. aurora'' occurs in Mic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stichodactylidae
Stichodactylidae is a family of sea anemones that contains the genera ''Stichodactyla'' (carpet anemones) and ''Heteractis''. These sea anemones exclusively reside within the shallow waters of the tropical Indo-Pacific area and are in the main family of sea anemones that hosts several varieties of clownfishes. Most sea anemone species are harmless to humans, but at least some ''Stichodactyla'' are highly venomous and their sting may cause anaphylactic shock and organ failure (notably acute liver failure). In contrast, the venom of ''Heteractis '' has shown potential in treatment of lung cancer. Discovery Collingwood C. first discovered ''Stichodactylidae'' back in 1868 after taking note on the existence of gigantic sea-anemones in the China Sea, containing quasi-parasitic fish. Genera and species The following species are recognized within the family Stichodactylidae: *Genus ''Heteractis'' **''Heteractis aurora'' **Sebae anemone (''Heteractis crispa'') **''Heteractis magnifica' ...

Jean René Constant Quoy
Jean René Constant Quoy (10 November 1790 in Maillé, Vendée, Maillé – 4 July 1869 in Rochefort, Charente-Maritime, Rochefort) was a French naval surgeon, zoologist and anatomist. In 1806, he began his medical studies at the school of naval medicine at Rochefort, Charente-Maritime, Rochefort, afterwards serving as an auxiliary-surgeon on a trip to the Antilles (1808–1809). After earning his medical doctorate in 1814 at Montpellier, he was surgeon-major on a journey to Réunion (1814–1815). Along with Joseph Paul Gaimard, he served as naturalist and surgeon aboard the ''Uranie'' under Louis de Freycinet from 1817 to 1820, and on the ''French ship Astrolabe (1817), Astrolabe'' (1826–1829) under the command of Jules Dumont d'Urville. In July 1823 he and Gaimard presented a paper to the Académie royale des Sciences on the origin of coral reefs, taking issue with the then widespread belief that these were constructed by coral polyps from bases in very deep water and arguin ...

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. 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 p ...

Taxa Named By Joseph Paul Gaimard
In biology, a taxon (back-formation from ''taxonomy''; plural 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. 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 set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...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, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echin ...

Western Australian Museum
The Western Australian Museum is a statutory authority within the Culture and the Arts Portfolio, established under the ''Museum Act 1969''. The museum has six main sites. The state museum, now known as WA Museum Boola Bardip, officially re-opened on 21 November 2020 in the Perth Cultural Centre. The other sites are: the WA Maritime Museum and WA Shipwrecks Museum in Fremantle, the Museum of the Great Southern in Albany, the Museum of Geraldton in Geraldton, and the Museum of the Goldfields in Kalgoorlie-Boulder. History Established in 1891 in the 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; Tunney ventured across the state from 1895 to 1909 obtaining animals and, later, the tools and artefacts of the indigenous inhabi ...

Panglao Island
Panglao is an island in the north Bohol Sea, located in the Central Visayas region of the Visayas island group, in the south-central Philippines. Geography The island has an area of . It is within Bohol Province, and comprises two municipalities: Dauis and Panglao. Panglao island is located southwest of the island of Bohol and east and south of Cebu. Panglao has a terrain that ranges from plain, hilly to mountainous. Panglao is made of Maribojoc limestone, the youngest of the limestone units found in the western area of Bohol. The limestone composition delayed the development of the international airport as coralline limestone is soluble which causes formation of caves and sinkholes. One interesting geological feature found in the island is the Hinagdanan Cave which has an underground water source. The cave is an important water source as the island has no rivers or lakes. Panglao is a popular tourist destination in the Philippines and includes several small islands, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timor
Timor is an island at the southern end of Maritime Southeast Asia, in the north of the Timor Sea. The island is East Timor–Indonesia border, divided between the sovereign states of East Timor on the eastern part and Indonesia on the western part. The Indonesian part, also known as West Timor, constitutes part of the Provinces of Indonesia, province of East Nusa Tenggara. Within West Timor lies an exclave of East Timor called Oecusse District. The island covers an area of . The name is a variant of ''timur'', Malay language, Malay for "east"; it is so called because it lies at the eastern end of the Lesser Sunda Islands. Mainland Australia is less than 500 km away, separated by the Timor Sea. Language, ethnic groups and religion Anthropologists identify eleven distinct Ethnolinguistic group, ethno-linguistic groups in Timor. The largest are the Atoni of western Timor and the Tetum of central and eastern Timor. Most indigenous Timorese languages belong to the Timorâ ...

Threespot Dascyllus
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. Its grey to black body has two lateral white spots and one between the eyes like domino hence the name; the threespot dascyllus grows up to 13 cm in length. Coloration is somewhat variable; the spot on the forehead may be absent and the lateral spots very much reduced. It feeds on algae, copepods and other planktonic crustaceans.Allen, G.R., 1991. Damselfishes of the world. Mergus Publishers, Melle, Germany. 271 p. Habitat Generally, adults are found in small groups around coral heads or large rocks. Juveniles may be found associated with large sea anemones or sheltering between the spines of diadema sea urchins or branching coral ...

Periclimenes
''Periclimenes'', commonly known as glass shrimp or cleaner shrimp, is a commensal and often symbiotic genus of semi-transparent shrimp within the family Palaemonidae. Species of this large genus feature a wide variety of coloration and patterns, widespread distribution throughout much of the world's tropical oceans, and are often sought out for aquarium trade. Taxonomy This genus has undergone several changes in classification based on recent molecular studies comparing species within the genus. However, most recent molecular studies have only involved approximately 20% of the known species likely to belong to the genus. Additionally, most of the molecular studies performed involved Indo-Pacific species of ''Periclimenes'' and did not include presumed ''Periclimenes'' found in the Atlantic Ocean. ''Periclimenes'' has previously been suggested as being a polyphyletic taxa, and has already undergone splits into several new genera. It is likely the genus will undergo changes in ...

Porcelain Crab
Porcelain crabs are decapod crustaceans in the widespread family Porcellanidae, which superficially resemble true crabs. They have flattened bodies as an adaptation for living in rock crevices. They are delicate, readily losing limbs when attacked, and use their large claws for maintaining territories. They first appeared in the Tithonian age of the Late Jurassic epoch, 145–152 million years ago. Description Porcelain crabs are small, usually with body widths less than . They share the general body plan of a squat lobster, but their bodies are more compact and flattened, an adaptation for living and hiding under rocks. Porcelain crabs are quite fragile animals, and often shed their limbs to escape predators, hence their name. The lost appendage can grow back over several moults. Porcelain crabs have large chelae (claws), which are used for territorial struggles, but not for catching food. The fifth pair of pereiopods is reduced and used for cleaning.
