Nembrotha Purpureolineata
''Nembrotha purpureolineata'' is a species of colourful sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Polyceridae. ''Nembrotha rutilans'', classified as a separate species until 2008, has now been reclassified as ''Nembrotha purpureolineata''.Pola M., Cervera J. L. & Gosliner T. M. (2008) "Revision of the Indo-Pacific genus ''Nembrotha'' (Nudibranchia: Dorididae: Polyceridae), with description of two new species". ''Scientia Marina'' 72(1): 145-183. Taxonomy ''Nembrotha purpureolineata'' was first described from a preserved specimen collected from Abrolhos Islands off Western Australia by O'Donoghue in 1924. The short colour description given is probably enough to identify it to be the same as ''Nembrotha rutilans'' ( Pruvot-Fol, 1931). The description of this species was done purely from a painting of marine life on the Great Barrier Reef in a book by William Saville-Kent, (1893) William Saville-Kent W.

Sea Slug
Sea slug is a common name for some marine invertebrates with varying levels of resemblance to terrestrial slugs. Most creatures known as sea slugs are gastropods, i.e. they are sea snails (marine gastropod mollusks) that over evolutionary time have either completely lost their shells, or have seemingly lost their shells due to having a greatly reduced or internal shell. The name "sea slug" is most often applied to nudibranchs, as well as to a paraphyletic set of other marine gastropods without obvious shells. Sea slugs have an enormous variation in body shape, color, and size. Most are partially translucent. The often bright colors of reef-dwelling species implies that these animals are under constant threat of predators, but the color can serve as a warning to other animals of the sea slug's toxic stinging cells (nematocysts) or offensive taste. Like all gastropods, they have small, razor-sharp teeth, called radulas. Most sea slugs have a pair of rhinophores—sensory te ...

Ascidian
Ascidiacea, commonly known as the ascidians, tunicates (in part), and sea squirts (in part), is a polyphyletic class in the subphylum Tunicata of sac-like marine invertebrate filter feeders. Ascidians are characterized by a tough outer "tunic" made of a polysaccharide. Ascidians are found all over the world, usually in shallow water with salinities over 2.5%. While members of the Thaliacea and Larvacea (Appendicularia) swim freely like plankton, sea squirts are sessile animals after their larval phase: they then remain firmly attached to their substratum, such as rocks and shells. There are 2,300 species of ascidians and three main types: solitary ascidians, social ascidians that form clumped communities by attaching at their bases, and compound ascidians that consist of many small individuals (each individual is called a zooid) forming colonies up to several meters in diameter. Sea squirts feed by taking in water through a tube, the oral siphon. The water enters the mouth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nembrotha Chamberlaini
''Nembrotha chamberlaini'' is a species of colorful sea slug, a dorid nudibranch, a marine gastropod mollusk in the family Polyceridae. It was first described in 1997. Distribution This species is known only from the Philippines and Indonesia Description ''Nembrotha chamberlaini'' is white with streaks of orange, yellow, green, or black and occasionally yellow splashed across the upper mantle. It has very distinctive bright red gills and rhinophores. The foot and mouth parts are typically light-purple. This nudibranch has a very characteristic color pattern which is typical of species that display warning coloration to other species. ''Nembrotha chamberlaini'' is easily confused with ''Nembrotha aurea'' and ''Nembrotha purpureolineata''. All three species have a similar range of color variation although ''N. aurea'' often has orange patches not present in ''Nembrotha chamberlaini''. ''N. chamberlaini'' can reach a length of 100 mm.

Rhinophore
A rhinophore is one of a pair of chemosensory club-shaped, rod-shaped or ear-like structures which are the most prominent part of the external head anatomy in sea slugs, marine gastropod opisthobranch mollusks such as the nudibranchs, sea hares (Aplysiomorpha), and sap-sucking sea slugs (Sacoglossa). Etymology The name relates to the rhinophore's function as an organ of "smell". ''Rhino-'' means nose from Ancient Greek ῥίς ''rhis'' and from its genitive ῥινός ''rhinos''. "Phore" means "to bear" from New Latin ''-phorus'' and from Greek -phoros (φορος) "bearing", a derivative of ''phérein'' (φέρειν). Function Rhinophores are scent or taste receptors, also known as chemosensory organs situated on the dorsal surface of the head. They are primarily used for distance chemoreception and rheoreception (response to water current). The "scents" detected by rhinophores are chemicals dissolved in the sea water. The fine structure and hairs of the rhinophor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Notum
The notum (plural nota) is the dorsal portion of an insect's thoracic segment, or the dorsal surface of the body of nudibranch gastropods. The word "notum" is always applied to dorsal structures; in other words structures that are part of the back of an animal, as opposed to being part of the animal's ventral surface, or underside. This word is used in entomology, the study of insects, and in malacology, the study of mollusks. In malacology the word is used to describe the back of the body of the taxonomic group of marine, shell-less gastropods that are known as nudibranchs. In insects In entomology, the notum is the dorsal portion of an insect's thoracic segment. The pterothoracic nota (comprising the meso- and metathoracic segments) have two main divisions - the anterior wing-bearing alinotum and the posterior phragma-bearing postnotom.Cranston, P. S, and P.

Doridoidea
Doridoidea, commonly known as dorid nudibranchs (and previously known as the taxon Cryptobranchia), are a taxonomic superfamily of medium to large, shell-less sea slugs, marine gastropod mollusks in the clade Doridacea, included in the clade Nudibranchia. Etymology The word "Doridoidea" comes from the generic name ''Doris'', which was in turn copied from the name of the sea nymph, Doris, in Greek mythology. Families According to the Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), families within the superfamily Doridoidea include: * Actinocyclidae O'Donoghue, 1929 * Chromodorididae Bergh, 1891 * Discodorididae Bergh, 1891 * Dorididae Rafinesque, 1815 Changes later than 2005 The family Cadlinidae Bergh, 1891 was considered a synonym of the Chromodorididae. Research by R.F. Johnson in 2011 has shown that ''Cadlina'' does not belong to the family Chromodorididae. She has therefore brought back the name ''Cadlinidae'' from synonymy with ''Chromodorididae''. The chromodori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indo-Pacific
The Indo-Pacific is a vast biogeographic region of Earth. In a narrow sense, sometimes known as the Indo-West Pacific or Indo-Pacific Asia, it comprises the tropical waters of the Indian Ocean, the western and central Pacific Ocean, and the seas connecting the two in the general area of Indonesia. It does not include the temperate and polar regions of the Indian and Pacific oceans, nor the Tropical Eastern Pacific, along the Pacific coast of the Americas, which is also a distinct marine realm. The term is especially useful in marine biology, ichthyology, and similar fields, since many marine habitats are continuously connected from Madagascar to Japan and Oceania, and a number of species occur over that range, but are not found in the Atlantic Ocean. The region has an exceptionally high species richness, with the world's highest species richness being found in at its heart in the Coral Triangle, and a remarkable gradient of decreasing species richness radiating outward in al ...

William Saville-Kent
William Saville-Kent (10 July 1845 – 11 October 1908) was an English marine biologist and author. Early life Born in the town of Sidmouth in Devon, South West England on 10 July 1845, William Saville-Kent was the son of Samuel Saville Kent (7 July 1800 – 5 February 1872) and Mary Ann Windus (b. 1808 – May 1852), who was Samuel's first wife. William was the youngest of ten children from his father's first marriage. Samuel was employed as a "Factory Commissioner" for the Home Office, and inspected factories to ensure that they were properly implementing the worker safety measures regulated in the Factory Acts of 1833. As the acts sought to alleviate the harm done to children that were caused by unregulated working conditions in the factories, Samuel's “duties required him to inspect factories that employed women and children.” Despite having “ambitions for promotion,” Samuel “suffered from the effects of local gossip and disapproval,” as a consequence of him be ...

Houtman Abrolhos
The Houtman Abrolhos (often called the Abrolhos Islands) is a chain of 122 islands and associated coral reefs, in the Indian Ocean off the west coast of Australia, about west of Geraldton, Western Australia. It is the southernmost true coral reef in the Indian Ocean, and one of the highest latitude reef systems in the world. It is one of the world's most important seabird breeding sites, and is the centre of Western Australia's largest single-species fishery, the western rock lobster fishery. It has a small seasonal population of fishermen, and a limited number of tourists are permitted for day trips, but most of the land area is off limits as conservation habitat. It is well known as the site of numerous shipwrecks, the most famous being the Dutch ships , which was wrecked in 1629, and , wrecked in 1727. The islands are an unincorporated area with no municipal government, subject to direct administration of the Government of Western Australia. In July 2019, the Houtman Abro ...

Mollusc
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.
