Sepia Latimanus
''Sepia latimanus'', also known as the broadclub cuttlefish, is widely distributed from the Andaman Sea, east to Fiji, and south to northern Australia. It is the most common cuttlefish species on coral reefs, living at a depth of up to 30 m. Naming and taxonomy The type specimen of ''Sepia latimus'' was collected in New Guinea and is deposited at the Muséum National d'Histoire Naturelle in Paris. This species has a wide geographic range and it is probable that it represents a species complex rather than a single species but more taxonomic work needs to be carried out to assess its species limits. The World Register of Marine Species lists the broadclub cuttlefish under the genus ''Ascarosepion''; within this genus it is grouped with 13 other species, such as the ''Metasepia'' cuttlefish, the reaper cuttlefish, and the giant cuttlefish. Description The broadclub cuttlefish is the second largest cuttlefish species after ''Sepia apama'', growing to in mantle length ...

Sipadan
Sipadan ( ms, Pulau Sipadan) is the only oceanic island in Malaysia, rising from the seabed. It is located in the Celebes Sea off the east coast of Sabah, Malaysia. It was formed by living corals growing on top of an extinct volcanic cone that took thousands of years to develop. Sipadan is located at the heart of the Indo-Pacific basin, the centre of one of the richest marine habitats in the world. More than 400 species of fish and hundreds of coral species have been classified in this ecosystem. Sipadan Island was at the top of Rodale's Scuba Diving Magazine Gold List for 'The Top Dive Destination in the World'. In fact it shared its top spot with 2 other destinations known for the diversity of their marine life — the Galápagos Islands of Ecuador and Truk in Micronesia. Further more, one of the dive operatorsScuba Junkiewas voted by the public the "Best Dive Resort in the World 2020" at DiveMagazine's annual Dive Travel Awards.

Porites
''Porites'' is a genus of stony coral; they are small polyp stony (SPS) corals. They are characterised by a finger-like morphology. Members of this genus have widely spaced calices, a well-developed wall reticulum and are bilaterally symmetrical. ''Porites'', particularly '' Porites lutea'', often form microatolls. Corals of the genus ''Porites'' also often serve as hosts for Christmas tree worms (''Spirobranchus giganteus''). Aquarium trade Specimens of ''Porites'' are sometimes available for purchase in the aquarium trade. Due to the strict water quality, lighting and dietary requirements, keeping ''Porites'' in captivity is very difficult. Paleoclimatology Porites corals have been shown to be accurate and precise recorders of past marine surface conditions. Measurements of the oxygen isotopic composition of the aragonitic skeleton of coral specimens indicate the sea-surface temperature conditions and the oxygen isotopic composition of the seawater at the time of growth. ...

Palaemon (crustacean)
''Palaemon'' is a genus of caridean shrimp of the family Palaemonidae. The conventional circumscription of the genus ''Palaemon'' is probably paraphyletic. Molecular data suggest that ''Palaemonetes'', as well as the genera '' Exopalaemon'' and '' Couteriella'', are nested within ''Palaemon''. Phylogenetic affinities in these groups correspond better with geographical origin than conventional genus assignments. Members The genus contains the following species: *'' Palaemon adspersus'' Rathke, 1837 *'' Palaemon affinis'' H. Milne-Edwards, 1837 *'' Palaemon capensis'' (De Man ''in'' M. Weber, 1897) *'' Palaemon carteri'' (Holthuis, 1950) *'' Palaemon concinnus'' Dana, 1852 (mangrove prawn) *'' Palaemon curvirostris'' Nguyên, 1992 *'' Palaemon debilis'' Dana, 1852 *'' Palaemon dolospinus'' Walker & Poore, 2003 *'' Palaemon elegans'' Rathke, 1837 (rockpool prawn) *'' Palaemon floridanus'' Chace, 1942 (Florida grass shrimp) *'' Palaemon gladiator'' Holthuis, 1950 *'' Palaemon gracili ...

Prawn
Prawn is a common name for small aquatic crustaceans with an exoskeleton and ten legs (which is a member of the order decapoda), some of which can be eaten. The term "prawn"Mortenson, Philip B (2010''This is not a weasel: a close look at nature's most confusing terms''Pages 106–109, John Wiley & Sons. . is used particularly in the United Kingdom, Ireland, and Commonwealth nations, for large swimming crustaceans or shrimp, especially those with commercial significance in the fishing industry. Shrimp that are present in this category often belong to the suborder Dendrobranchiata. In North America, the term is used less frequently, typically for freshwater shrimp. The terms shrimp and prawn themselves lack scientific standing. Over the years, the way they are used has changed, and in contemporary usage the terms are almost interchangeable. Shrimp'' vs. ''prawn Regional distinctions The terms shrimp and prawn originated in Britain. In the use of common names for species, shrim ...

Shrimp
Shrimp are crustaceans (a form of shellfish) with elongated bodies and a primarily swimming mode of locomotion – most commonly Caridea and Dendrobranchiata of the decapod order, although some crustaceans outside of this order are referred to as "shrimp". More narrow definitions may be restricted to Caridea, to smaller species of either group or to only the marine species. Under a broader definition, ''shrimp'' may be synonymous with prawn, covering stalk-eyed swimming crustaceans with long, narrow muscular tails (abdomens), long whiskers ( antennae), and slender legs. Any small crustacean which resembles a shrimp tends to be called one. They swim forward by paddling with swimmerets on the underside of their abdomens, although their escape response is typically repeated flicks with the tail driving them backwards very quickly. Crabs and lobsters have strong walking legs, whereas shrimp have thin, fragile legs which they use primarily for perching.Rudloe & Rudloe (2009 ...

Mesmerise
Hypnosis is a human condition involving focused attention (the selective attention/selective inattention hypothesis, SASI), reduced peripheral awareness, and an enhanced capacity to respond to suggestion.In 2015, the American Psychological Association Division 30 defined hypnosis as a "state of consciousness involving focused attention and reduced peripheral awareness characterized by an enhanced capacity for response to suggestion". For critical commentary on this definition, see: There are competing theories explaining hypnosis and related phenomena. ''Altered state'' theories see hypnosis as an altered state of mind or trance, marked by a level of awareness different from the ordinary state of consciousness. In contrast, ''non-state'' theories see hypnosis as, variously, a type of placebo effect,Kirsch, I., "Clinical Hypnosis as a Nondeceptive Placebo", pp. 211–25 in Kirsch, I., Capafons, A., Cardeña-Buelna, E., Amigó, S.

Coral Sea
The Coral Sea () is a marginal sea of the South Pacific off the northeast coast of Australia, and classified as an interim Australian bioregion. The Coral Sea extends down the Australian northeast coast. Most of it is protected by the French Natural Park of the Coral Sea (french: Parc Naturel de la Mer de Corail) and the Australian Coral Sea Marine Park. The sea was the location for the Battle of the Coral Sea, a major confrontation during World War II between the navies of the Empire of Japan, and the United States and Australia. The sea contains numerous islands and reefs, as well as the world's largest reef system, the Great Barrier Reef (GBR), which was declared a World Heritage Site by UNESCO in 1981. All previous oil exploration projects were terminated at the GBR in 1975, and fishing is restricted in many areas. The reefs and islands of the Coral Sea are particularly rich in birds and aquatic life and are a popular tourist destination, both domestically and internat ...

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 ...

Mantle (mollusc)
The mantle (also known by the Latin word pallium meaning mantle, robe or cloak, adjective pallial) is a significant part of the anatomy of molluscs: it is the dorsal body wall which covers the visceral mass and usually protrudes in the form of flaps well beyond the visceral mass itself. In many species of molluscs the epidermis of the mantle secretes calcium carbonate and conchiolin, and creates a shell. In sea slugs there is a progressive loss of the shell and the mantle becomes the dorsal surface of the animal. The words mantle and pallium both originally meant cloak or cape, see mantle (vesture). This anatomical structure in molluscs often resembles a cloak because in many groups the edges of the mantle, usually referred to as the ''mantle margin'', extend far beyond the main part of the body, forming flaps, double-layered structures which have been adapted for many different uses, including for example, the siphon. Mantle cavity The ''mantle cavity'' is a central fea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
