Orectolobus Reticulatus
''Orectolobus reticulatus'', the network wobbegong, is a recently described species of carpet shark found in relatively shallow waters off Kimberley and Darwin in north-western Australia.Last, P.R., J.J. Pogonoski, & W. T. White. (2008). ''Orectolobus reticulatus sp. nov., a new wobbegong shark (Orectolobiformes: Orectolobidae) from the continental shelf of northwestern Australia.'' 39–47 in: Last, P.R., W. T. White, & J.J. Pogonoski, J.J. (eds). Descriptions of new Australian chondrichthyans. CSIRO Marine and Atmospheric Research Paper 22: 1–358 0, figs 1-3 With a known maximum length of only , it may be the smallest species of wobbegong. Until its description in 2008, it had been confused with the northern wobbegong. The network wobbegong has a short snout, broad head, elongated body, and two dorsal fins, with the first being slightly larger than the second. Its body is grayish brown with darker brown markings and a pale yellow underbelly. The network wobbegong lives in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crustacean
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans ( Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by ...

Taxa Named By Peter R
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 int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Described In 2008
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most f ...

Orectolobus
''Orectolobus'' is a genus of carpet sharks in the family Orectolobidae. They are commonly known as wobbegongs, although this name also applies to the other members of the family. They are found in shallow temperate and tropical waters of the western Pacific Ocean and eastern Indian Ocean, chiefly around Australia and Indonesia, although one species (the Japanese wobbegong, ''O. japonicus'') occurs as far north as Japan. They have a mottled or spotted cryptic pattern, and have elongated dermal lobes in the region near the mouth. Most have a maximum length of or less, but two species, '' O. halei'' and '' O. maculatus'', reach about (earlier reports of similar-sized '' O. ornatus'' is due to confusion with ''O. halei''). These sluggish ambush predators are typically seen resting on the seafloor, and at least some species are nocturnal. While usually harmless to humans, they have been known to bite, but generally only if stepped on, approached too closely, or provoked. Spec ...

CSIRO
The Commonwealth Scientific and Industrial Research Organisation (CSIRO) is an Australian Government agency responsible for scientific research. CSIRO works with leading organisations around the world. From its headquarters in Canberra, CSIRO maintains more than 50 sites across Australia and in France, Chile and the United States, employing about 5,500 people. Federally funded scientific research began in Australia years ago. The Advisory Council of Science and Industry was established in 1916 but was hampered by insufficient available finance. In 1926 the research effort was reinvigorated by establishment of the Council for Scientific and Industrial Research (CSIR), which strengthened national science leadership and increased research funding. CSIR grew rapidly and achieved significant early successes. In 1949, further legislated changes included renaming the organisation as CSIRO. Notable developments by CSIRO have included the invention of atomic absorption spectroscopy, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Wobbegong
The northern wobbegong (''Orectolobus wardi'') is a carpet shark in the family Orectolobidae, found in the western Pacific Ocean around Australia, between latitudes 9° S to 26° S. It reaches a length of 63 cm. Captivity Northern wobbegongs are excellent aquarium sharks due to their small (30 inch) adult size. They can be successfully reared in 135 gallon aquaria, but sharks in general tend to do better in aquaria 180 gallons or more in volume.

Continental Shelf
A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water, known as a shelf sea. Much of these shelves were exposed by drops in sea level during glacial periods. The shelf surrounding an island is known as an ''insular shelf''. The continental margin, between the continental shelf and the abyssal plain, comprises a steep continental slope, surrounded by the flatter continental rise, in which sediment from the continent above cascades down the slope and accumulates as a pile of sediment at the base of the slope. Extending as far as 500 km (310 mi) from the slope, it consists of thick sediments deposited by turbidity currents from the shelf and slope. The continental rise's gradient is intermediate between the gradients of the slope and the shelf. Under the United Nations Convention on the Law of the Sea, the name continental shelf was given a legal definition as the stretch of the seabed adjacent to the shores of a ...

Darwin Harbour
Darwin Harbour is the body of water close to Darwin in the Northern Territory of Australia. It opens to the north at a line from Charles Point in the west to Lee Point in the east into the Beagle Gulf and connects via the Clarence Strait with the Van Diemen Gulf.N Smit, R Billyard and L Ferns: Beagle Gulf Benthic Survey: Characterisation of soft substrates.'' Technical Report No. 66 (2000), Parks and Wildlife Commission of the Northern Territory. It contains Port Darwin, which is flanked by Frances Bay to the east and Cullen Bay to the west. Name Darwin Harbour was named after the naturalist Charles Darwin, who sailed with captain Robert Fitzroy on the second expedition of the ''Beagle'' (December 1831 – October 1836) which visited parts of Australia. During the voyage, he became a friend of the officers, including John Lort Stokes and John Clements Wickham who were promoted for the next voyage of the ship. Lieutenant Stokes was apparently the first British person t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long Reef (New South Wales)
Long Reef is a prominent headland in the Northern Beaches of Sydney, Australia. Connected to the mainland by a tombolo, the reef has an extensive wave-cut platform. Long Reef is a popular recreational destination and is one of the more interesting geological areas in Sydney. Geology Some of the oldest rocks in the Sydney area may be seen at Long Reef. Primarily from the Triassic they are from the Narrabeen Group of sedimentary rocks. The cliffs of Long Reef are composed of Bald Hill Claystone above Bulgo Sandstone. There was a wide volcanic dyke made of dolerite, two metres tall from the Jurassic. However, this has been reduced by mining. The most commonly seen type of rock in Sydney, Hawkesbury sandstone, is absent at Long Reef. It is present at Dee Why headland, a small distance to the south, separated by a fault under Dee Why beach. A copper mine was active at Long Reef in the 1880s,information sign at Long Reef – by the local council after a tunnel was drilled ...
