Siganus Punctatus
''Siganus punctatus'' the goldspotted spinefoot, goldspotted rabbitfish, punctuated spinefoot, spotted rabbitfish, spotted spinefoot or yellow-spotted spinefoot, is a species of marine ray-finned fish, a rabbitfish belonging to the family Siganidae. It occurs in the Indo-West Pacific region. Taxonomy ''Siganus punctatus'' was first formally described in 1801 as ''Amphacanthus punctatus'' by Johann Gottlob Theaenus Schneider and Johann Reinhold Forster with the type locality given as Nomuka Island in the Ha'apai Group of Tonga. The specific name ''punctatus'' means “spotted”, a reference to the golden spots on the head, body and tail. Description ''Siganus punctatus'' has a laterally compressed, deep body which has a depth which fits into its standard length between 1.9 and 2.3 times. The head has a straight dorsal profile, it runs from the forehead to the snout at an angle of 45°, while the ventral profile is slightly indented underneath the chin. In fish of less than ...

Johann Gottlob Theaenus Schneider
Johann Gottlob Theaenus Schneider (18 January 1750 – 12 January 1822) was a German classicist and naturalist. Biography Schneider was born at Collm in Saxony. In 1774, on the recommendation of Christian Gottlob Heine, he became secretary to the famous Strasbourg scholar Richard François Brunck, and in 1811 became professor of ancient languages and eloquence at Breslau (chief librarian, 1816) where he died in 1822. Works Of his numerous works the most important was his ''Kritisches griechisch-deutsches Handwörterbuch'' (1797–1798), the first independent work of the kind since Stephanus's ''Thesaurus'', and the basis of F. Passow's and all succeeding Greek lexicons (including, therefore, the contemporary standard '' A Greek-English Lexicon''). A special improvement was the introduction of words and expressions connected with natural history and science. In 1801 he corrected and expanded re-published Marcus Elieser Bloch's ''Systema Ichthyologiae iconibus cx illustratum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ocellus
A simple eye (sometimes called a pigment pit) refers to a form of eye or an optical arrangement composed of a single lens and without an elaborate retina such as occurs in most vertebrates. In this sense "simple eye" is distinct from a multi-lensed "compound eye", and is not necessarily at all simple in the usual sense of the word. The structure of an animal's eye is determined by the environment in which it lives, and the behavioural tasks it must fulfill to survive. Arthropods differ widely in the habitats in which they live, as well as their visual requirements for finding food or conspecifics, and avoiding predators. Consequently, an enormous variety of eye types are found in arthropods. They possess a wide variety of novel solutions to overcome visual problems or limitations. Use of the term ''simple eye'' is flexible, and must be interpreted in proper context; for example, the eyes of humans and of other large animals such as most cephalopods, are ''camera eyes'' and ...

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 ...

Timor Sea
The Timor Sea ( id, Laut Timor, pt, Mar de Timor, tet, Tasi Mane or ) is a relatively shallow sea bounded to the north by the island of Timor, to the east by the Arafura Sea, and to the south by Australia. The sea contains a number of reefs, uninhabited islands and significant hydrocarbon reserves. International disputes emerged after the reserves were discovered resulting in the signing of the Timor Sea Treaty. The Timor Sea was hit by the worst oil spill for 25 years in 2009. It is possible that Australia's first inhabitants crossed the Timor Sea from the Malay Archipelago at a time when sea levels were lower. Etymology The Timor Sea is named after Timor, the island on the other side of the sea's northern coastline. The island's name is a variant of , Malay for "east". In Tetum, the expression () is often used to refer to the Timor Sea. The counterpart of that body of water, the ' Ombai-Wetar Strait', which has smaller waves, is less turbid, and washes most of Timor ...

Scott And Seringapatam Reefs
Scott and Seringapatam Reefs is a group of atoll-like reefs in the Timor Sea more than northwest of Cape Leveque, Western Australia, on the edge of the continental shelf. There are three or four separate reef structures, depending on whether Scott Reef Central is counted separately. The group is just one of a number of reef formations off the northwest coast of Australia and belongs to Western Australia. Further to the northeast are Ashmore and Cartier Islands, and to the southwest are the Rowley Shoals. Location and Description Each of the reefs rises steeply from the seabed below. Much of the reef area dries at low tide, but besides Sandy Islet of Scott Reef South, there are only a few rocks and sandbanks above the high water mark. *Scott Reef South (also Horseshoe Reef or South Reef) is a large crescent-shaped formation that has a rare and unusual double reef crest. Its lagoon, has depths of over throughout the greater portion. The reef with its lagoon covers an area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rowley Shoals
The Rowley Shoals is a group of three atoll-like coral reefs south of the Timor Sea, about west of Broome on the northwestern Australian coast, centered on , on the edge of one of the widest continental shelves in the world. Each atoll covers an area of around within the rim of the reef, including the lagoons, while the land areas are negligible. They belong to Western Australia. They all rise steeply from the surrounding ocean floor. To the northeast lie the Scott and Seringapatam Reefs which are located on the same undersea platform. Naming and history The Rowley Shoals were so named by Captain Phillip Parker King in 1818 in honour of Captain Rowley who first sighted the ''Imperieuse Reef'' in 1800. It is believed that the Rowley Shoals reefs have been visited by fishermen from Indonesia, from at least the mid-18th century. The fishermen were also collecting or hunting for Trepang (holothurians or sea cucumbers), turtle shell, trochus shell and shark fin. These early vi ...

North West Solitary Island
North West Solitary Island is an island found off the New South Wales coast and inside the continental shelf. It is located 30 km north-east of Coffs Harbour and about 18 km south of Wooli. The island is part of the Solitary Islands Marine Park established 2 January 1998 and managed by the New South Wales Maritime Parks Authority. Rocks on North West Solitary Island consist of repeating beds of sillicaceous argillite, mudstone and sandstone. The argillite probably formed from volcanic ash falls. The beds are 5 to 10 cm thick. The strike of the beds is between 0° and 20° with overturned beds dipping to the east. The mudstone shows cleavage at an angle steeper than the bedding planes by 20°. Tectonically it is part of the Coffs Harbour Block which in turn is part of the New England Orogen The Hunter-Bowen Orogeny was a significant arc accretion event in the Permian and Triassic periods affecting approximately 2,500 km of the Australian continental margin. ...

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] |
Rottnest Island
Rottnest Island ( nys, Wadjemup), often colloquially referred to as "Rotto", is a island off the coast of Western Australia, located west of Fremantle. A sandy, low-lying island formed on a base of aeolianite limestone, Rottnest is an A-class reserve, the highest level of protection afforded to public land. Together with Garden Island, Rottnest Island is a remnant of Pleistocene dune ridges. Along with several other islands, Rottnest became separated from the mainland around 7,000 years ago, when sea levels rose; the traditional Noongar name for the island is ''Wadjemup'', which means "place across the water where the spirits are". Human artefacts have been found on the island dating back at least 30,000 years, but visitation and habitation of the island by the Noongar people appears to have ceased following its separation from the mainland. The island was first documented by Willem de Vlamingh in 1696, who called it t Eylandt 't Rottenest'' ("Rats' Nest Island") after the qu ...

Ogasawara Islands
The Bonin Islands, also known as the , are an archipelago of over 30 subtropical and tropical islands, some directly south of Tokyo, Japan and northwest of Guam. The name "Bonin Islands" comes from the Japanese word ''bunin'' (an archaic reading of ''mujin''), meaning "no people" or "list of uninhabited regions, uninhabited". The only inhabited islands of the group are Chichijima (), the seat of the municipal government, and Hahajima (). Archeological evidence has revealed that some of the islands may have been prehistorically inhabited by members of an unknown Micronesian ethnicity. Ogasawara, Tokyo, Ogasawara Municipality (''mura'') and Ogasawara Subprefecture take their names from the Ogasawara Group. The is also used as a wider collective term that includes other islands in Ogasawara Municipality, such as the Volcano Islands, along with three other remote islands (Nishinoshima (Ogasawara), Nishinoshima, Minamitorishima, and Okinotorishima).
