Urolophus Flavomosaicus
The patchwork stingaree (''Urolophus flavomosaicus'') is a little-known species of stingray in the family Urolophidae, with a disjunct distribution off northwestern and northeastern Australia. It usually inhabits the outer continental shelf, at a depth of . This species has a diamond-shaped pectoral fin disc much wider than long, and a short, flattened tail with a prominent dorsal fin and leaf-like caudal fin. There is a skirt-shaped curtain of skin between its nostrils. Its dorsal color pattern resembles a mosaic of dark brown rings with light-colored centers, separated by fine reticulated lines. The International Union for Conservation of Nature (IUCN) has listed the patchwork stingaree under Least Concern, as it is subject to minimal fishing pressure. Taxonomy Peter Last and Martin Gomon described the patchwork stingaree in a 1987 issue of ''Memoirs of the National Museum of Victoria'', giving it the specific epithet ''flavomosaicus'' from the Latin ''flavus'' ("yellow") ...

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...

Mosaic
A mosaic is a pattern or image made of small regular or irregular pieces of colored stone, glass or ceramic, held in place by plaster/mortar, and covering a surface. Mosaics are often used as floor and wall decoration, and were particularly popular in the Ancient Roman world. Mosaic today includes not just murals and pavements, but also artwork, hobby crafts, and industrial and construction forms. Mosaics have a long history, starting in Mesopotamia in the 3rd millennium BC. Pebble mosaics were made in Tiryns in Mycenean Greece; mosaics with patterns and pictures became widespread in classical times, both in Ancient Greece and Ancient Rome. Early Christian basilicas from the 4th century onwards were decorated with wall and ceiling mosaics. Mosaic art flourished in the Byzantine Empire from the 6th to the 15th centuries; that tradition was adopted by the Norman Kingdom of Sicily in the 12th century, by the eastern-influenced Republic of Venice, and among the Rus. Mosaic fell ou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Cape Leveque
Cape Leveque is at the northernmost tip of the Dampier Peninsula in the Kimberley region of Western Australia. Cape Leveque is (via the Cape Leveque Road) north of Broome, and is remote with few facilities. Nevertheless, the Cape's sandy beaches are attracting an increasing number of visitors. The lighthouse was commissioned at Cape Leveque on 9 August 1911. Its light characteristic is a group of three flashes that occurs every twenty seconds whereby the light source emits from a focal plane of . The lighthouse marks the western entrance of King Sound. Cape Leveque was a camping ground for ancient nomadic people of northern Australia and is probably still being used today. Their huge middens overshadow the small caravan park resting on the shores of the Indian Ocean. Wild turtles and a multitude of sea birds nest on the shores and collect seafood off the exposed rocks at low tide along the shore down the coast to Broome in the southern part of the peninsula.

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 ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butterfly Stingaree
The butterfly stingaree (''Urolophus papilio'') is a little-known species of stingray in the family Urolophidae, endemic to the continental slope off the Chesterfield Islands. This species is characterized by a diamond-shaped pectoral fin disc much wider than long, and a rather short tail terminating in a leaf-shaped caudal fin, as well as bearing a dorsal fin and sometimes indistinct lateral skin folds. There is a skirt-shaped flap of skin between its nostrils. It is plain yellowish to brownish above, and reaches a length of at least . The International Union for Conservation of Nature (IUCN) has listed this ray as of Least Concern, since no commercial trawl fishing occurs within its range. Taxonomy The butterfly stingaree was described by Bernard Séret and Peter Last in a 2003 issue of the scientific journal ''Cybium''; the specific epithet, ''"papilio"'' (Latin for "butterfly"), refers to its wide disc. The first known specimens were collected during a series of research crui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandyback Stingaree
The sandyback stingaree or great stingaree (''Urolophus bucculentus'') is a little-known species of stingray in the family Urolophidae, endemic to southeastern Australia. It is generally found offshore around the edge of the continental shelf, at a depth of . A relatively large species reaching long, the sandyback stingaree has a diamond-shaped pectoral fin disc wider than long, usually with a dorsal pattern of numerous fine lighter marks on a yellowish to brownish background. Its short tail terminates in a deep, leaf-shaped caudal fin, and bears a sizable dorsal fin just in front of the stinging spine. A bottom-dwelling predator taking mostly crustaceans, the sandyback stingaree is aplacental viviparous: females supply their unborn young with histotroph ("uterine milk"), bearing up to five pups every other year following a 14–19-month gestation period. Significant numbers of this species are taken incidentally by commercial fisheries, primarily off New South Wales wher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Specimen
In biology, a type is a particular wiktionary:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the ...

Trawl
Trawling is a method of fishing that involves pulling a fishing net through the water behind one or more boats. The net used for trawling is called a trawl. This principle requires netting bags which are towed through water to catch different species of fishes or sometimes targeted species. Trawls are often called towed gear or dragged gear. The boats that are used for trawling are called trawlers or draggers. Trawlers vary in size from small open boats with as little as 30 hp (22 kW) engines to large factory trawlers with over 10,000 hp (7.5 MW). Trawling can be carried out by one trawler or by two trawlers fishing cooperatively ( pair trawling). Trawling can be contrasted with trolling. While trawling involves a net and is typically done for commercial usage, trolling instead involves a reed, rod and a bait or a lure and is typically done for recreational purposes. Trawling is also commonly used as a scientific sampling, or survey, method. Bottom vs. midwater trawlin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Hedland, Western Australia
Port Hedland ( Kariyarra: ''Marapikurrinya'') is the second largest town in the Pilbara region of Western Australia, with an urban population of 14,320 Estimated resident population, 30 June 2018. at June 2018 including the satellite town of South Hedland, away. It is also the site of the highest tonnage port in Australia. Port Hedland has a natural deep anchorage harbour which, as well as being the main fuel and container receival point for the region, was seen as perfect for shipment of the iron ore being mined in the ranges located inland from the town. The ore is moved by railway from four major iron ore deposits to the east and south of the Port Hedland area. The port exported of iron ore (2017–2018). Other major resource activities supported by the town include the offshore natural gas fields, salt, manganese, and livestock. Major deposits of lithium are being developed and exploited south of the town as well. Grazing of cattle and sheep was formerly a major revenue e ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...
