Chromodoris Westraliensis
''Chromodoris westraliensis'' is a species of very colourful sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae.Caballer, M. (2011)''Chromodoris westraliensis'' (O'Donoghue, 1924).Accessed through: World Register of Marine Species on 2011-01-13 Distribution This species of nudibranch occurs in coastal regions of Western Australia, from the Kimberley region in the north of the state, to its southern occurrence near Esperance. It is the most abundant nudibranch of the Perth region. Description The length of this animal is up to 65 millimetres. A mantle covers the upper parts of the animal and extends to form a skirt at the sides. The colouring is two (or one) bright blue patches on a black background, with an orange outline. This aposematic coloration advertises its toxicity to would-be predators. Two sensory organs, tentacle shaped rhinophores, are orange, and are located at the upper surface of the head. The gills, clustered and plumose, are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Henry O'Donoghue
Charles Henry O'Donoghue FRSE FZS (23 September 1885 – 28 November 1961) was an English zoologist who studied molluscs, a malacologist. His publications mostly deal with sea slugs and he also named a number of Bryozoans. A collection of over 700 items left to the University of Reading is known as the O'Donoghue Collection. Life He was born in Bedfordshire on 23 September 1885 the son of Charles Henry O'Donoghue. He studied zoology at University College London, receiving his degree from the University of London. From 1918 to 1927 he was Professor of Zoology at the University of Manitoba. From 1923 he additionally acted as Director of the Marine Biological Station at Nanaimo on Vancouver Island. He also helped to establish the Prince Rupert Island and Cultus Lake research stations. In 1928 he became a Reader in natural history at the University of Edinburgh. In 1928 he was elected a Fellow of the Royal Society of Edinburgh. His proposers were James Hartley Ashworth, John Ste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kimberley (Western Australia)
The Kimberley is the northernmost of the nine regions of Western Australia. It is bordered on the west by the Indian Ocean, on the north by the Timor Sea, on the south by the Great Sandy Desert, Great Sandy and Tanami Desert, Tanami deserts in the region of the Pilbara, and on the east by the Northern Territory. The region was named in 1879 by government surveyor Alexander Forrest after Secretary of State for the Colonies John Wodehouse, 1st Earl of Kimberley. History The Kimberley was one of the earliest settled parts of Australia, with the first humans landing about 65,000 years ago. They created a complex culture that developed over thousands of years. Yam (vegetable), Yam (''Dioscorea hastifolia'') agriculture was developed, and rock art suggests that this was where some of the earliest boomerangs were invented. The worship of Wandjina deities was most common in this region, and a complex theology dealing with the transmigration of souls was part of the local people's religi ...

Sponge
Sponges or sea sponges are primarily marine invertebrates of the animal phylum Porifera (; meaning 'pore bearer'), a basal clade and a sister taxon of the diploblasts. They are sessile filter feeders that are bound to the seabed, and are one of the most ancient members of macrobenthos, with many historical species being important reef-building organisms. Sponges are multicellular organisms consisting of jelly-like mesohyl sandwiched between two thin layers of cells, and usually have tube-like bodies full of pores and channels that allow water to circulate through them. They have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. They do not have complex nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes, usually via flagella movements of the so-called " collar ...

Rhinophore
A rhinophore is one of a pair of Chemoreceptor, chemosensory club-shaped, rod-shaped or ear-like structures which are the most prominent part of the external head anatomy in sea slugs, Marine (ocean), 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 Neo-Latin ''-phorus'' and from Greek -phoros (φορος) "bearing", a derivative of ''phérein'' (φέρειν). Function Rhinophores are scent or taste receptors, also known as Chemoreceptor, 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 ...

Aposematic Coloration
Aposematism is the advertising by an animal, whether terrestrial or marine, to potential predators that it is not worth attacking or eating. This unprofitability may consist of any defenses which make the prey difficult to kill and eat, such as toxicity, venom, foul taste or smell, sharp spines, or aggressive nature. These advertising signals may take the form of conspicuous coloration, sounds, odours, or other perceivable characteristics. Aposematic signals are beneficial for both predator and prey, since both avoid potential harm. The term was coined in 1877 by Edward Bagnall Poulton for Alfred Russel Wallace's concept of warning coloration. Aposematism is exploited in Müllerian mimicry, where species with strong defences evolve to resemble one another. By mimicking similarly coloured species, the warning signal to predators is shared, causing them to learn more quickly at less of a cost. A genuine aposematic signal that a species actually possesses chemical or physical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Department Of Conservation And Land Management
The Department of Conservation and Land Management (CALM) was a department of the Government of Western Australia that was responsible for implementing the state's conservation and environment legislation and regulations. It was created by the ''Conservation and Land Management Act 1984'', also known as the ''CALM Act'', which is still in force . The Department of Conservation and Land Management was responsible from 22 March 1985 to 30 June 2006 for protecting and conserving the State of Western Australia’s environment; this included managing the state's national parks, marine parks, conservation parks, state forests, timber reserves and nature reserves. The Conservation Commission of Western Australia, responsible for assessing and auditing the performance of the department, was also created by the ''CALM Act''. Now ( renamed the Conservation and Parks Commission), its functions have broadened, with its purpose stated as "to act as an independent and trusted community stew ...

Basionym
In the scientific name of organisms, basionym or basyonym means the original name on which a new name is based; the author citation of the new name should include the authors of the basionym in parentheses. The term "basionym" is used in both botany and zoology. In zoology, alternate terms such as original combination or protonym are sometimes used instead. Bacteriology uses a similar term, basonym, spelled without an ''i''. Although "basionym" and "protonym" are often used interchangeably, they have slightly different technical definitions. A basionym is the ''correct'' spelling of the original name (according to the applicable nomenclature rules), while a protonym is the ''original'' spelling of the original name. These are typically the same, but in rare cases may differ. When creating new taxonomic names, there are specific rules about how basionyms can be used. A new combination or name at new rank must be based directly on the original basionym rather than on any intermediate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chromodorididae
Chromodorididae, or chromodorids, are a taxonomic family of colourful sea slugs; dorid nudibranchs, marine gastropod mollusks in the superfamily Doridoidea. “Chromodorid nudibranchs are among the most gorgeously coloured of all animals.” The over 360 described species are primarily found in tropical and subtropical waters, as members of coral reef communities, specifically associated with their sponge prey. The chromodorids are the most speciose family of opisthobranchs. They range in size from <10mm to over 30 cm, although most species are approximately 15–30 mm in size. Although, they have a worldwide distribution, most species are found in the region. A scientific paper published in 2007, found the most widespread chromodorid genera, ('' [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family (, : ) 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". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...
