Delagoa Bay
Delagoa is a marine ecoregion along the eastern coast of Africa. It extends along the coast of Mozambique and South Africa from the Bazaruto Archipelago (21°14’ S) to Lake St. Lucia in South Africa (28° 10' S) in South Africa's Kwazulu-Natal province. It adjoins the Bight of Sofala/Swamp Coast ecoregion to the north, and the Natal ecoregion to the south. It has Africa's southernmost tropical coral reefs and mangrove forests. It is the southernmost Indo-Pacific ecoregion, marking the transition from the tropical Indo-Pacific to Temperate Southern Africa. Geography The dominant shoreline feature in the ecoregion is sandy beaches backed by coastal dunes. The dunes can reach up to 120 meters in height, and older dunes are vegetated. Behind the coastal dunes are lagoons, including river estuaries, closed saline lagoons, and salt lakes. The warm Agulhas Current runs southward parallel to the coast. Habitat types Seagrass meadows are found in sheltered waters behind coastal i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Indo-Pacific
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.Spalding, Mark D., Helen E.

Seagrass Meadow
A seagrass meadow or seagrass bed is an underwater ecosystem formed by seagrasses. Seagrasses are marine (saltwater) plants found in shallow coastal waters and in the brackish waters of estuaries. Seagrasses are flowering plants with stems and long green, grass-like leaves. They produce seeds and pollen and have roots and rhizomes which anchor them in seafloor sand. Seagrasses form dense underwater meadows which are among the most productive ecosystems in the world. They provide habitats and food for a diversity of marine life comparable to that of coral reefs. This includes invertebrates like shrimp and crabs, cod and flatfish, marine mammals and birds. They provide refuges for endangered species such as seahorses, turtles, and dugongs. They function as nursery habitats for shrimps, scallops and many commercial fish species. Seagrass meadows provide coastal storm protection by the way their leaves absorb energy from waves as they hit the coast. They keep coastal waters health ...

Bazaruto National Park
The Bazaruto Archipelago National Park (BANP) is a protected area in the Inhambane Province of Mozambique on the Bazaruto Archipelago. The park was proclaimed on 25 May 1971. It is off the coast of the Vilanculos and Inhassoro districts, covering a large expanse of ocean and five islands. Location The Bazaruto National Park was inaugurated in 1971. It consists of an archipelago of five islands off the Mozambican coast between Vilankulo and Inhassoro. The park was created to protect dugong and marine turtles, and their habitats. The islands' flora and fauna, coral reefs and marine birds were also included. The largest island of the archipelago is Bazaruto Island and the others are Benguerra, Margaruque, Santa Carolina (Paradise Island), and Banque. Ecology The islands have a lush tropical climate and include huge dunes, forest and savannah, inland lakes and wetlands. They host several endemic terrestrial gastropods and lizards, as well as important aggregations of Palaea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manta Ray
Manta rays are large Batoidea, rays belonging to the genus ''Mobula'' (formerly its own genus ''Manta''). The larger species, ''Giant oceanic manta ray, M. birostris'', reaches in width, while the smaller, ''Reef manta ray, M. alfredi'', reaches . Both have triangular Pectoral fin#AnchPectoral, pectoral fins, horn-shaped cephalic fins and large, forward-facing mouths. They are classified among the Myliobatiformes (stingrays and relatives) and are placed in the Family (biology), family Eagle ray, Myliobatidae (eagle rays). They have the largest brain-to-body ratio of all fish, and can pass the mirror test. Mantas are found in warm temperate, subtropical and tropical waters. Both species are Pelagic fish, pelagic; ''M. birostris'' Animal migration, migrates across open oceans, singly or in groups, while ''M. alfredi'' tends to be resident and coastal. They are filter feeders and eat large quantities of zooplankton, which they gather with their open mouths as they swim. However, ...

Whale Shark
The whale shark (''Rhincodon typus'') is a slow-moving, filter feeder, filter-feeding carpet shark and the largest known Extant taxon, extant fish species. The largest confirmed individual had a length of . The whale shark holds many records for size in the animal kingdom, most notably being by far the most massive living non-cetacean animal. It is the sole member of the genus ''Rhincodon'' and the only extant member of the family Rhincodontidae, which belongs to the subclass Elasmobranchii in the class Chondrichthyes. Before 1984 it was classified as ''Rhiniodon'' into Rhinodontidae. Whale sharks inhabit the open waters of all tropical oceans. They are rarely found in water below . Whale sharks' lifespans are estimated to be between 80 and 130 years, based on studies of their vertebral growth bands and the growth rates of free-swimming sharks. Whale sharks have very large mouths and are filter feeders, which is a feeding mode that occurs in only two other sharks, the megamouth s ...

Loggerhead Sea Turtle
The loggerhead sea turtle (''Caretta caretta'') is a species of sea turtle, oceanic turtle distributed throughout the world. It is a marine reptile, belonging to the Family (biology), family Cheloniidae. The average loggerhead measures around in carapace length when fully grown. The adult loggerhead sea turtle weighs approximately , with the largest specimens weighing in at more than . The skin ranges from yellow to brown in color, and the shell is typically reddish brown. No external differences in sex are seen until the turtle becomes an adult, the most obvious difference being the adult males have thicker tails and shorter plastrons (lower shells) than the females. The loggerhead sea turtle is found in the Atlantic Ocean, Atlantic, Pacific Ocean, Pacific, and Indian Oceans, as well as the Mediterranean Sea. It spends most of its life in saltwater and estuarine habitats, with females briefly coming ashore to lay eggs. The loggerhead sea turtle has a low reproductive rate; fem ...

Dugong
The dugong (; ''Dugong dugon'') is a marine mammal. It is one of four living species of the order Sirenia, which also includes three species of manatees. It is the only living representative of the once-diverse family Dugongidae; its closest modern relative, Steller's sea cow (''Hydrodamalis gigas''), was hunted to extinction in the 18th century. The dugong is the only sirenian in its range, which spans the waters of some 40 countries and territories throughout the Indo-West Pacific. The dugong is largely dependent on seagrass communities for subsistence and is thus restricted to the coastal habitats that support seagrass meadows, with the largest dugong concentrations typically occurring in wide, shallow, protected areas such as bays, mangrove channels, the waters of large inshore islands, and inter-reefal waters. The northern waters of Australia between Shark Bay and Moreton Bay are believed to be the dugong's contemporary stronghold. Like all modern sirenians, the d ...

Komati River
The Komati River, also known as the Inkomati River or Incomati River (in Mozambique, from Portuguese Rio Incomati), is a river in South Africa, Eswatini and Mozambique. Originating in north-western Eswatini, it is joined by the Crocodile River in the Lebombo Mountains, enters far south-western Mozambique below the border town of Komatipoort, and enters the Indian Ocean around north-east of Maputo. It is long, with a drainage basin in size. Its mean annual discharge is 111 m3/s (3,920 cfs) at its mouth. The name Komati is derived from ''inkomati'', meaning "cow" in siSwati, as its perennial nature is compared to a cow that always has milk. Geography The river originates west of Carolina, rising at an elevation of about near Breyten in the Ermelo district of the Mpumalanga province. It flows in a general northeasterly direction and reaches the Indian Ocean at Maputo Bay, after a course of some . The Komati Gorge is situated in the upper reaches of the Komati ...

Limpopo River
The Limpopo River () rises in South Africa and flows generally eastward through Mozambique to the Indian Ocean. The term Limpopo is derived from Rivombo (Livombo/Lebombo), a group of Tsonga settlers led by Hosi Rivombo who settled in the mountainous vicinity and named the area after their leader. The river has been called the Vhembe by local Venda communities of the area where now that name has been adopted by the South African government as its District Municipality in the north, a name that was also suggested in 2002 as a possible title for the province but was voted against. The river is approximately long, with a drainage basin of in size. The mean discharge measured over a year is to at its mouth. The Limpopo is the second largest African river that drains to the Indian Ocean, after the Zambezi River. The first European to sight the river was Vasco da Gama, who anchored off its mouth in 1498 and named it Espirito Santo River. Its lower course was explored by ...

Ascidiacea
Ascidiacea, commonly known as the ascidians or sea squirts, is a paraphyletic class in the subphylum Tunicata of sac-like marine invertebrate filter feeders. Ascidians are characterized by a tough outer test or "tunic" made of the polysaccharide cellulose. Ascidians are found all over the world, usually in shallow water with salinities over 2.5%. While members of the Thaliacea (salps, doliolids and pyrosomes) and Appendicularia (larvaceans) swim freely like plankton, sea squirts are sessile animals after their larval phase: they then remain firmly attached to their substratum, such as rocks and shells. There are 2,300 species of ascidians and three main types: solitary ascidians, social ascidians that form clumped communities by attaching at their bases, and compound ascidians that consist of many small individuals (each individual is called a zooid) forming large colonies. Sea squirts feed by taking in water through a tube, the oral siphon. The water enters the mouth and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
