Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or approximately 20% of the water area of Earth#Surface, Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia (continent), Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. The Indian Ocean has large marginal or regional seas, including the Andaman Sea, the Arabian Sea, the Bay of Bengal, and the Laccadive Sea. Geologically, the Indian Ocean is the youngest of the oceans, and it has distinct features such as narrow continental shelf, continental shelves. Its average depth is 3,741 m. It is the warmest ocean, with a significant impact on global climate due to its interaction with the atmosphere. Its waters are affected by the Indian Ocean Walker circulation, resulting in unique oceanic currents and upwelling patterns. The Indian Ocean is ecologically diverse, with important ecosystems such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frigate
A frigate () is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied. The name frigate in the 17th to early 18th centuries was given to any full-rigged ship built for speed and maneuverability, intended to be used in scouting, escort and patrol roles. The term was applied loosely to ships varying greatly in design. In the second quarter of the 18th century, what is now generally regarded as the 'true frigate' was developed in France. This type of vessel was characterised by possessing only one armed deck, with an unarmed deck below it used for berthing the crew. Late in the 19th century (British and French prototypes were constructed in 1858), a type of powerful ironclad warships was developed, and because they had a single gun deck, the term 'frigate' was used to describe them. Later developments in ironclad ships rendered the 'frigate' designation obsolete and the term fell out of favour. During the Second World War ...

Hawksbill Turtles
The hawksbill sea turtle (''Eretmochelys imbricata'') is a critically endangered sea turtle belonging to the family Cheloniidae. It is the only extant species in the genus ''Eretmochelys''. The species has a global distribution that is largely limited to tropical and subtropical marine and estuary ecosystems. The appearance of the hawksbill is similar to that of other marine turtles. In general, it has a flattened body shape, a protective carapace, and flipper-like limbs, adapted for swimming in the open ocean. ''E. imbricata'' is easily distinguished from other sea turtles by its sharp, curving beak with prominent tomium, and the saw-like appearance of its shell margins. Hawksbill shells slightly change colors, depending on water temperature. While this turtle lives part of its life in the open ocean, it spends more time in shallow lagoons and coral reefs. The World Conservation Union, primarily as a result of human fishing practices, classifies ''E. imbricata'' as criticall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
House Sparrow
The house sparrow (''Passer domesticus'') is a bird of the Old World sparrow, sparrow family Passeridae, found in most parts of the world. It is a small bird that has a typical length of and a mass of . Females and young birds are coloured pale brown and grey, and males have brighter black, white, and brown markings. One of about 25 species in the genus ''Passer'', the house sparrow is native to most of Europe, the Mediterranean Basin, and a large part of Asia. Its intentional or accidental introduced species, introductions to many regions, including parts of Australasia, Africa, and the Americas, make it the most widely distributed wild bird. The house sparrow is strongly associated with human habitation, and can live in urban or rural settings. Though found in widely varied habitats and climates, it typically avoids extensive woodlands, grasslands, polar regions, and hot, dry deserts far away from human development. For sustenance, the house sparrow routinely feeds at h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grey Plover
The grey plover or black-bellied plover (''Pluvialis squatarola'') is a large plover breeding in Arctic regions. It is a long-distance migrant, with a nearly worldwide coastal distribution when not breeding. Taxonomy The grey plover was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Tringa squatarola''. It is now placed with three other plovers in the genus ''Pluvialis'' that was introduced by the French ornithologist Mathurin Jacques Brisson in 1760. The genus name is Latin and means relating to rain, from ''pluvia'', "rain". It was believed that they flocked when rain was imminent. The species name ''squatarola'' is a Latinised version of ''Sgatarola'', a Venetian name for some kind of plover. The English common name used for this species differs in different parts of the world. It is generally known as "grey plover" in the Old World and "black-bellied plover" in the New World. T ...

Ruddy Turnstone
The ruddy turnstone (''Arenaria interpres'') is a small Cosmopolitan distribution, cosmopolitan wader, wading bird, one of two species of turnstone in the genus ''Arenaria''. It is now classified in the sandpiper family Scolopacidae but was formerly sometimes placed in the plover family Charadriidae. It is a highly bird migration, migratory bird, breeding in northern parts of Palearctic, Eurasia and North America, and flying south to winter on coastlines almost worldwide. It is the only species of turnstone in much of its range and is often known simply as turnstone. Taxonomy The ruddy turnstone was Species description, formally described by the Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of Systema Naturae, tenth edition of his ''Systema Naturae'' under the binomial nomenclature, binomial name ''Tringa interpres''. The species is now placed together with the black turnstone in the genus ''Arenaria (bird), Arenaria'' that was introduced by the French zoologist Ma ...

Eurasian Whimbrel
The Eurasian or common whimbrel (''Numenius phaeopus''), also known as the white-rumped whimbrel in North America, is a wader in the large family Scolopacidae. It is one of the most widespread of the curlews, breeding across much of subarctic Palearctic, Asia and Europe as far south as Scotland. This species and the Hudsonian whimbrel have recently been split based on genetic and morphological differences as well as no overlap in breeding ranges, although some taxonomic authorities still consider them to be conspecific. Taxonomy The Eurasian whimbrel was Species description, formally described by the Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of Systema Naturae, tenth edition of his ''Systema Naturae'' under the binomial nomenclature, binomial name ''Scolopax phaeopus''. It is now placed with the curlews in the genus ''Curlew, Numenius'' that was introduced by the French ornithologist Mathurin Jacques Brisson in 1760. The genus name ''Numenius'' is from Ancient G ...

Saunders's Tern
Saunders's tern (''Sternula saundersi''), sometimes known as the black-shafted tern, is a species of bird in the family Laridae. It is sparsely resident along the shores of the north-western Indian Ocean (namely southern Somalia, Arabian Peninsula, Socotra, Pakistan, Andaman and Nicobar Islands and northern Sri Lanka). It is a close relative of the little tern, least tern, yellow-billed tern, and Peruvian tern. In non-breeding plumages, the Saunder's tern and the little tern may be almost indistinguishable. The two have been considered by some to be conspecific. Description Saunders's tern shares many of the features of its close relative, the little tern, including a white body, a black-tipped yellow bill, and a black cap with a white forehead patch. In its breeding plumage, it distinguishes itself with a straight-bordered forehead patch, possessing more black outer primaries, and duskier colored legs and feet in comparison to the bright yellow legs of the little tern.

Crab Plover
The crab-plover or crab plover (''Dromas ardeola)'' is a coastal wader (shorebird). It is the only member of the genus ''Dromas'' and the family Dromadidae. It is unique among waders in making use of ground warmth to aid the incubation of its eggs. The crab-plover is classified in the suborder Lari, making it more closely related to gulls and auks than to most other waders such as plovers (suborder Charadrii) and sandpipers (suborder Scolopaci). Description This bird resembles a plover, but has very long grey legs and a strong heavy black bill similar to a tern. Its black-and-white plumage and long-necked upright posture with heavy bill makes it distinctive and unmistakable. Its bill is unique among waders, and specialised for eating crabs. It has partially webbed toes. The plumage is white except for black on its back and in the primary feathers of the wings. They are noisy birds, calling frequently on their breeding sites and in their wintering grounds. The usual call is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Shearwater
The tropical shearwater (''Puffinus bailloni'') is a seabird in the family Procellariidae formerly considered conspecific with Audubon's shearwater (''Puffinus lherminieri''). Subspecies There are five listed subspecies of the tropical shearwater: * ''Puffinus bailloni nicolae'' – ( Jouanin, 1971): breeds on islands in the northwest Indian Ocean. * ''Puffinus bailloni colstoni'' – ( Shirihai & Christie, 1996): breeds in the Aldabra Islands in the Seychelles. * ''Puffinus bailloni bailloni'' – ( Bonaparte, 1857): Mauritius, Réunion & Europa Island. * ''Puffinus bailloni dichrous'' – ( Finsch & Hartlaub, 1867): Central Pacific islands. * ''Puffinus bailloni gunax'' – ( Mathews, 1930): Vanuatu.

Black-naped Tern
The black-naped tern (''Sterna sumatrana'') is an oceanic tern mostly found in tropical and subtropical areas of the Indian Ocean and western Pacific Ocean. They are rarely found inland. It was described from the islands around Sumatra. It is most closely related to roseate tern ''S. dougallii'' and white-fronted tern ''S. striata''. Description The Black-naped tern is named from the black band beginning at the eyes connecting behind the head and descending the back of the neck. The rest of their plumage is white, with pale silvery-grey wings and mantle, apart from the outermost primary feather which has a narrow black outer web. The tail is white, and deeply forked, extending (like the related roseate and white-fronted terns) beyond the wingtips on perched birds. The beaks and legs are black. They have a body length of 30-35 cm and a wingspan of 66 cm. Adults weigh between 97-120 g. Hatchlings are motled brown. Taxonomy There are two listed subspecies: *''S. s. sumatrana'' ( ...
