Walters Shoals
The Walters Shoals is a group of submerged mountains off the coast of Madagascar. The shoals are south of Cape Sainte Marie - Madagascar and east of Richards Bay at the African coast. The tips of some of the mountains are only below the surface. The Walters Shoals is home to many species of fish, crustaceans, and mollusks. It was discovered in 1963 by the South African Hydrographic Frigate SAS ''Natal'' captained by Cmdr Walters. When found it had a huge population of Galápagos shark The Galapagos shark (''Carcharhinus galapagensis'') is a species of requiem shark, in the family Carcharhinidae, found worldwide.

Seamount
A seamount is a large geologic landform that rises from the ocean floor that does not reach to the water's surface (sea level), and thus is not an island, islet or cliff-rock. Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to in height. They are defined by oceanographers as independent features that rise to at least above the seafloor, characteristically of conical form.IHO, 2008. Standardization of Undersea Feature Names: Guidelines Proposal form Terminology, 4th ed. International Hydrographic Organization and Intergovernmental Oceanographic Commission, Monaco. The peaks are often found hundreds to thousands of meters below the surface, and are therefore considered to be within the deep sea. During their evolution over geologic time, the largest seamounts may reach the sea surface where wave action erodes the summit to form a flat surface. After they have subsided and sunk below the sea surface such flat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Richards Bay
Richards Bay ( af, Richardsbaai) is a town in KwaZulu-Natal, South Africa. It is situated on a 30 square kilometre lagoon of the Mhlatuze River, which makes it one of the country's largest harbours. Richards Bay also has the deepest natural harbour on the African continent. History The town began as a makeshift harbour that was set up by Commodore of the Cape, Sir Markus Eugene Brown, during the Anglo-Zulu War of 1879. In 1902, Cathcart Methven, the harbour engineer for the Natal Government, in his ''Zululand Port Survey'' recognized the potential of Richards Bay as a new harbour for the eastern shore. In 1935 the Richards Bay Game Sanctuary was created to protect the ecology around the lagoon and by 1943 it expanded into Richards Bay Park. The town was laid out on the shores of the lagoon in 1954 and proclaimed a town in 1969. In 1965, the South African Government under Minister of Transport Ben Schoeman decided to build a deep water harbour at Richards Bay. Construction wo ...

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMSAS Natal (K10)
HMSAS ''Natal'' (pennant number: K10) was one of three s in the South African Navy (SAN). It was built as HMS ''Loch Cree'' (K430) for the Royal Navy during World War II, but was transferred to the SAN before completion in 1945 and renamed as HMSAS ''Natal''. Just hours after finishing fitting out, the ship sank a German submarine off the coast of Scotland in early 1945. It was assigned convoy escort duties for the remaining few months of the war in Europe. ''Natal'' had her anti-aircraft armament reinforced for service in the Far East after arriving in South Africa in June. In September–October, the ship participated in the reoccupation of British Malaya before returning home the following month. It was assigned to ferry troops home from Egypt afterwards and participated in the annexation of the Prince Edward Islands in late 1947. Together with her sister ships, ''Natal'' made port visits in Middle Africa in 1948. It was placed in reserve in 1953 and was converted into a surv ...

Galápagos Shark
The Galapagos shark (''Carcharhinus galapagensis'') is a species of requiem shark, in the family Carcharhinidae, found worldwide. It favors clear reef environments around oceanic islands, where it is often the most abundant shark species. A large species that often reaches , the Galapagos reef shark has a typical fusiform "reef shark" shape and is very difficult to distinguish from the dusky shark (''C. obscurus'') and the grey reef shark (''C. amblyrhynchos''). An identifying character of this species is its tall first dorsal fin, which has a slightly rounded tip and originates over the rear tips of the pectoral fins. The Galapagos shark is an active predator often encountered in large groups. It feeds mainly on bottom-dwelling bony fishes and cephalopods; larger individuals have a much more varied diet, consuming other sharks, marine iguanas, sea lions, and even garbage. As in other requiem sharks, reproduction is viviparous, with females bearing litters of 4–16 pups ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has some large marginal or regional seas such as the Arabian Sea, Laccadive Sea, Bay of Bengal, and Andaman Sea. Etymology The Indian Ocean has been known by its present name since at least 1515 when the Latin form ''Oceanus Orientalis Indicus'' ("Indian Eastern Ocean") is attested, named after Indian subcontinent, India, which projects into it. It was earlier known as the ''Eastern Ocean'', a term that was still in use during the mid-18th century (see map), as opposed to the ''Western Ocean'' (Atlantic Ocean, Atlantic) before the Pacific Ocean, Pacific was surmised. Conversely, Ming treasure voyages, Chinese explorers in the Indian Oce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Landforms Of Madagascar
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are the fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
