This is a list of the lists of islands in the world grouped by country, by continent, by body of water, and by other classifications. For rank-order lists, see the other lists of islands below.
The Neotropical realm is one of the eight biogeographic realms constituting Earth's land surface. Physically, it includes the tropical terrestrial ecoregions of the Americas and the entire South American temperate zone.
The Global 200 is the list of ecoregions identified by the World Wide Fund for Nature (WWF), the global conservation organization, as priorities for conservation. According to WWF, an ecoregion is defined as a "relatively large unit of land or water containing a characteristic set of natural communities that share a large majority of their species dynamics, and environmental conditions". For example, based on their levels of endemism, Madagascar gets multiple listings, ancient Lake Baikal gets one, and the North American Great Lakes get none.
A marine ecoregion is an ecoregion, or ecological region, of the oceans and seas identified and defined based on biogeographic characteristics.
The Western Indo-Pacific is a biogeographic region of the Earth's seas, comprising the tropical waters of the eastern and central Indian Ocean. It is part of the larger Indo-Pacific, which includes the tropical Indian Ocean, the western and central Pacific Ocean, and the seas connecting the two in the general area of Indonesia. The Western Indo-Pacific may be classified as a marine realm, one of the great biogeographic divisions of the world's ocean basins, or as a subrealm of the Indo-Pacific.
The Central Indo-Pacific is a biogeographic region of Earth's seas, comprising the tropical waters of the western Pacific Ocean, the eastern Indian Ocean, and the connecting seas.
Gymnothorax miliaris, the goldentail moray, bastard eel, or conger moray, is a species of marine fish in the family Muraenidae.
Tristan da Cunha is an archipelago of five islands in the southern Atlantic Ocean, the largest of which is the island of Tristan da Cunha itself and the second-largest, the remote bird haven, Gough Island. It forms part of a wider territory called Saint Helena, Ascension and Tristan da Cunha which includes Saint Helena and Ascension Island.
The lancer dragonet, Baird's dragonet, coral dragonet or St Helena dragonet, is a species of dragonet native to the warmer waters of the Atlantic Ocean where it occurs at depths of from 1 to 91 metres. In the western Atlantic it occurs from Cape Hatteras southwards along the east coast of North America. including Bermuda and the Bahamas, into the Gulf of Mexico and throughout the Caribbean Sea. It has also been recorded from Ilha da Trindade off Brazil. In the eastern Atlantic it has been recorded from the Cape Verde Islands, Ascension Island, St. Helena, and Sao Tome e Principe in the Gulf of Guinea. This species grows to a length of 11.4 centimetres (4.5 in) TL.
The Marine biodiversity of South Africa is the variety of living organisms that live in the seas off the coast of South Africa. It includes genetic, species and ecosystems biodiversity in a range of habitats spread over a range of ecologically varied regions, influenced by the geomorphology of the seabed and circulation of major and local water masses, which distribute both living organisms and nutrients in complex and time-variable patterns.
Kyphosus bigibbus, the brown chub, grey drummer, darkfin drummer, insular rudderfish, grey chub, grey sea chub, southern drummer or topsail drummer is a species of marine ray-finned fish, a sea chub from the family Kyphosidae. It is a herbivorous species which is found in subtropical and tropical seas worldwide.
Temperate Southern Africa is a biogeographic region of the Earth's seas, comprising the temperate waters of southern Africa, where the Atlantic Ocean and Indian Ocean meet. It includes the coast of South Africa and Namibia, and reaches into southern Angola. It also includes the remote islands of Amsterdam and Saint-Paul, to the east in the southern Indian Ocean.
Temperate South America is a biogeographic region of the Earth's seas, comprising the temperate and subtropical waters of South America, including both the Pacific and Atlantic coasts of the continent and adjacent islands. It also includes the remote Gough Island and Tristan da Cunha in the South Atlantic Ocean.
Temperate Australasia is a biogeographic region of the Earth's seas, comprising the temperate and subtropical waters of Australia and New Zealand, including both the Indian Ocean and Pacific coasts of the continent and adjacent islands.
The Temperate Northern Atlantic is a biogeographic region of the Earth's seas, comprising the temperate and subtropical waters of the North Atlantic Ocean and connecting seas, including the Mediterranean Sea, Black Sea, and northern Gulf of Mexico.
The Northeastern Brazil marine ecoregion covers the coastal marine environment around the Northeast Region of Brazil. The marine ecoregion extends from the mouth of the Parnaíba River in the west around the eastern point of the Brazilian mainland and south to the Bay of All Saints. The warm South Equatorial Current feeds warm tropical water into the region from the east. The Northeastern Brazil ecoregion is one of two coastal marine ecoregions in the Tropical Southwest Atlantic marine province. It is thus part of the Tropical Atlantic realm.
The Southeastern Brazil marine ecoregion covers the warm coastal waters to 250 miles offshore of southeastern Brazil, from the latitude of Rio de Janeiro in the north to Florianópolis in the south. Marine diversity is supported by local upwellings in the north and the inflow of the Brazil Current. The region is one of transition from a tropical to a warm temperate environment. The marine ecoregion is one of four coastal marine ecoregions in the Warm Temperate Southwestern Atlantic marine province. It is thus part of the Temperate South America realm. .
