Arc-eye Hawkfish
The arc-eye hawkfish (''Paracirrhites arcatus''), the ringeye hawkfish, horseshoe hawkfish or whiteline hawkfish, is a species of marine ray-finned fish, a hawkfish belonging to the family Cirrhitidae. It is found in shallow waters in the tropical Indo-Pacific on reefs, resting on coral heads much of the time. Taxonomy The arc-eye hawkfish was first formally described in 1829 as ''Cirrhites arcatus'' by the French zoologist Georges Cuvier with the type locality given as Mauritius. The specific name ''arcatus'' means “arched”, an allusion which Cuvier did not explain but it may refer to the horseshoe shaped mark behind the eye. Some authorities treat '' Paracirrhites amblycephalus'' as a valid species but Fishbase treats this taxon as a synonym of ''P. arcatus''. Description The arc-eye hawkfish has a relatively deep body, the standard length being around 2.7 times its length. It has a smooth upper preopercular margin and a slightly rounded to truncate caudal fin. The dors ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polynesia
Polynesia () "many" and νῆσος () "island"), to, Polinisia; mi, Porinihia; haw, Polenekia; fj, Polinisia; sm, Polenisia; rar, Porinetia; ty, Pōrīnetia; tvl, Polenisia; tkl, Polenihia (, ) is a subregion of Oceania, made up of more than 1,000 islands scattered over the central and southern Pacific Ocean. The indigenous people who inhabit the islands of Polynesia are called Polynesians. They have many things in common, including Polynesian languages, language relatedness, Polynesian culture, cultural practices, and Marae, traditional beliefs. In centuries past, they had a strong shared tradition of sailing and Polynesian navigation, using stars to navigate at night. The largest country in Polynesia is New Zealand. The term was first used in 1756 by the French writer Charles de Brosses, who originally applied it to all the list of islands in the Pacific Ocean, islands of the Pacific. In 1831, Jules Dumont d'Urville proposed a narrower definition during a lecture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 inter ...

Great Barrier Reef
The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over over an area of approximately . The reef is located in the Coral Sea, off the coast of Queensland, Australia, separated from the coast by a channel 100 miles wide in places and over 200 feet deep. The Great Barrier Reef can be seen from outer space and is the world's biggest single structure made by living organisms. This reef structure is composed of and built by billions of tiny organisms, known as coral polyps. It supports a wide diversity of life and was selected as a World Heritage Site in 1981. CNN labelled it one of the seven natural wonders of the world in 1997. Australian World Heritage places included it in its list in 2007. The Queensland National Trust named it a state icon of Queensland in 2006. A large part of the reef is protected by the Great Barrier Reef Marine Park, which helps to limit the impact of human use, suc ...

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 Ti ...

Muiron Islands
The Ningaloo Coast is a World Heritage Site located in the north west coastal region of Western Australia. The heritage-listed area is located approximately north of Perth, along the East Indian Ocean. The distinctive Ningaloo Reef that fringes the Ningaloo Coast is long and is Australia's largest fringing coral reef and the only large reef positioned very close to a landmass. The Muiron Islands and Cape Farquhar are within this coastal zone. The coast and reef draw their name from the Australian Aboriginal Wajarri language word ''ningaloo'' meaning "promontory", "deepwater", or "high land jutting into the sea". The Yamatji peoples of the Baiyungu and Yinigudura clans have inhabited the area for over 30,000 years. Ningaloo Coast World Heritage site The World Heritage status of the region was created and negotiated in 2011, and the adopted boundary included the Ningaloo Marine Park (Commonwealth waters), Ningaloo Marine Park (State waters) and Muiron Islands ...

Shark Bay
Shark Bay ( Malgana: ''Gathaagudu'', "two waters") is a World Heritage Site in the Gascoyne region of Western Australia. The http://www.environment.gov.au/heritage/places/world/shark-bay area is located approximately north of Perth, on the westernmost point of the Australian continent. UNESCO's official listing of Shark Bay as a World Heritage Site reads: : History The record of Australian Aboriginal occupation of Shark Bay extends to years BP. At that time most of the area was dry land, rising sea levels flooding Shark Bay between BP and BP. A considerable number of aboriginal midden sites have been found, especially on Peron Peninsula and Dirk Hartog Island which provide evidence of some of the foods gathered from the waters and nearby land areas. An expedition led by Dirk Hartog happened upon the area in 1616, becoming the second group of Europeans known to have visited Australia. (The crew of the '' Duyfken'', under Willem Janszoon, had visited Cape York in 1606 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitcairn Islands
The Pitcairn Islands (; Pitkern: '), officially the Pitcairn, Henderson, Ducie and Oeno Islands, is a group of four volcanic islands in the southern Pacific Ocean that form the sole British Overseas Territory in the Pacific Ocean. The four islands— Pitcairn, Henderson, Ducie and Oeno—are scattered across several hundred miles of ocean and have a combined land area of about . Henderson Island accounts for 86% of the land area, but only Pitcairn Island is inhabited. The islands nearest to the Pitcairn Islands are Mangareva (of French Polynesia) at 688 km to the west and Easter Island at 1,929 km to the east. The Pitcairn Islanders are a biracial ethnic group descended mostly from nine ''Bounty'' mutineers and a handful of Tahitian consorts—as is still apparent from the surnames of many of the islanders. The mutiny and its aftermath have been the subject of many books and films. As of January 2020, the territory had only 47 permanent inhabitants. History P ...

Hawaiian Islands
The Hawaiian Islands ( haw, Nā Mokupuni o Hawai‘i) are an archipelago of eight major islands, several atolls, and numerous smaller islets in the North Pacific Ocean, extending some from the island of Hawaii in the south to northernmost Kure Atoll. Formerly the group was known to Europeans and Americans as the Sandwich Islands, a name that James Cook chose in honor of the 4th Earl of Sandwich, the then First Lord of the Admiralty. Cook came across the islands by chance when crossing the Pacific Ocean on his Third Voyage in 1778, on board HMS ''Resolution''; he was later killed on the islands on a return visit. The contemporary name of the islands, dating from the 1840s, is derived from the name of the largest island, Hawaii Island. Hawaii sits on the Pacific Plate and is the only U.S. state that is not geographically connected to North America. It is part of the Polynesia subregion of Oceania. The state of Hawaii occupies the archipelago almost in its entirety (i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dorsal Fin
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through convergent evolution they have independently evolved external superficial fish-like body plans adapted to their marine environments, including most numerously fish, but also mammals such as cetaceans ( whales, dolphins, and porpoises), and even extinct ancient marine reptiles such as various known species of ichthyosaurs. Most species have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of large cetaceans to identify individuals in the field. The bony or cartilaginous bones that support the base of the dorsal fin in fish are called ''pterygiophores''. Functions The main purpose of the dorsal fin is to stabilize the animal against r ...
