Panulirus Cygnus
''Panulirus cygnus'' is a species of spiny lobster (family Palinuridae), found off the west coast of Australia. ''Panulirus cygnus'' is the basis of Australia's most valuable fishery, making up 20% of value of Australia's total fishing industry, and is identified as the western rock lobster. Taxonomy ''Panulirus cygnus'' was previously classified under several taxonomic arrangements, the description as a new species was published in 1962. The Western Australian crayfish was identified in 1916 as '' Panulirus penicillatus'' (Olivier, 1791). This was reassessed at the British Museum by Isabella Gordon in 1936 as '' Panulirus longipes'' at the request of Ludwig Glauert, a diagnosis that was conserved, despite further doubts, due to its extensive use by the state's crayfishing industry and associated legislation. The author, Ray George, recognised the similarities to other species of ''Panulirus'' in a comparative study, but proposed the anatomical characteristics were of an un ...

Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first permanent European colony of Western Australia occurred following the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tonne
The tonne ( or ; symbol: t) is a unit of mass equal to 1000 kilograms. It is a non-SI unit accepted for use with SI. It is also referred to as a metric ton to distinguish it from the non-metric units of the short ton ( United States customary units), and the long ton ( British imperial units). It is equivalent to approximately 2204.6 pounds, 1.102 short tons, and 0.984 long tons. The official SI unit is the megagram (symbol: Mg), a less common way to express the same mass. Symbol and abbreviations The BIPM symbol for the tonne is t, adopted at the same time as the unit in 1879.Table 6 . BIPM. Retrieved on 2011-07-10. Its use is also official for the metric ton in the United States, having been adopted by the United States |
Seagrasses Of Western Australia
The Seagrasses of Western Australia are submerged flowering plants found along the coast, around islands, and in Estuaries of Western Australia. The region contains some of the largest seagrass meadows in the world, and is the most diverse in the number of species. The variety of habitats along its western and southern coasts is often soft sands in shallow subtropical waters, ideal for these plants. Description Marine grasses are flowering plants that evolved from terrestrial grasses to habitat in coastal waters. In contrast to seaweeds, usually found on rocks, seagrass colonises sandy ocean beds to form dense stands and meadows. The Western Australian coastline, along with its islands, is over 20,000 km long. These tropical to temperate waters extend from latitudes 32-34°S to 12°S. The great diversity of habitat in these coastal regions of Western Australia are occupied by seagrasses, frequently 'engineering' habitat through colonisation of shallow ocean floors. These plants ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

North West Cape
North West Cape is a peninsula in the north-west of Western Australia. Cape Range runs down the spine of the peninsula and Ningaloo Reef runs along the western edge. It is in the Gascoyne region and includes the town of Exmouth. History In 1618, Dutch East India Company captain Lenaert Jacobszoon and supercargo Willem Janszoon of the ''Mauritius'' landed in the area. Phillip Parker King later visited in 1818 and named it ''North West Cape'' as well as naming Exmouth Gulf after senior naval officer Edward Pellew, 1st Viscount Exmouth. Later, pearl luggers visited the area from Broome. During World War II a military operation codenamed ''Operation Potshot'' was done in the area. The first oil flow in Australia was discovered there in 1953 at Rough Range, by exploration company WAPET. Exmouth Gulf Station takes up much of the eastern side of the peninsula backing onto Exmouth Gulf. See also * Exmouth, Western Australia * Cape Range National Park * United States Naval Communica ...

Hamelin Bay
Hamelin Bay is a bay and a locality on the southwest coast of Western Australia between Cape Leeuwin and Cape Naturaliste. It is named after French explorer Jacques Félix Emmanuel Hamelin, who sailed through the area in about 1801. It is south of Cape Freycinet. To the north, the beach leads to the '' Boranup Sand Patch'' and further to the mouth of the Margaret River, while south leads to Cape Leeuwin. The nearest locality to the east is Karridale on the Margaret River to Augusta road. It was also a small settlement and port in Western Australia on the coast of the Leeuwin-Naturaliste Ridge. Port and jetty The jetty was established to service the timber milling operations of Davies, at the same time as utilising a jetty at Flinders Bay just south of Augusta. One of the Davies timber railways extended onto the Hamelin Bay Jetty, which was built in 1882 and extended in 1898. Only a few piles of the original jetty remain on site.

Animal Diversity Web
Animal Diversity Web (ADW) is an online database that collects the natural history, classification, species characteristics, conservation biology, and distribution information on thousands of species of animals. The website includes thousands of photographs, hundreds of sound clips, and a virtual museum. Overview The ADW acts as an online encyclopedia, with each individual species account displaying basic information specific to that species. The website used a local, relational database written by staff and student contributors from the University of Michigan. Each species account includes geographic range, habitat, physical description, development, ecosystem roles, reproduction, life span, communication and perception, behavior, food habits, predation, and conservation status. The organization of the site reinforces past biology knowledge by providing sharp images and showing common phyla on the home page. The Animal Diversity Web has resources other than its databa ...

Carapace
A carapace is a Dorsum (biology), dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises. In turtles and tortoises, the underside is called the plastron. Crustaceans In crustaceans, the carapace functions as a protective cover over the cephalothorax (i.e., the fused head and thorax, as distinct from the abdomen behind). Where it projects forward beyond the eyes, this projection is called a rostrum (anatomy), rostrum. The carapace is Calcification, calcified to varying degrees in different crustaceans. Zooplankton within the phylum Crustacea also have a carapace. These include Cladocera, ostracods, and Isopoda, isopods, but isopods only have a developed "cephalic shield" carapace covering the head. Arachnids In arachnids, the carapace is formed by the fusion of prosomal tergites into a single Plate (animal anatomy), plate which carries the e ...

Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including such interested par ...

Paratype
In zoology and botany, a paratype is a specimen of an organism that helps define what the scientific name of a species and other taxon actually represents, but it is not the holotype (and in botany is also neither an isotype nor a syntype). Often there is more than one paratype. Paratypes are usually held in museum research collections. The exact meaning of the term ''paratype'' when it is used in zoology is not the same as the meaning when it is used in botany. In both cases however, this term is used in conjunction with ''holotype''. Zoology In zoological nomenclature, a paratype is officially defined as "Each specimen of a type series other than the holotype.", ''International Code of Zoological Nomenclature'' In turn, this definition relies on the definition of a "type series". A type series is the material (specimens of organisms) that was cited in the original publication of the new species or subspecies, and was not excluded from being type material by the author (th ...
