Aquatic Mammals
Aquatic mammals and semiaquatic mammals are a diverse group of mammals that dwell partly or entirely in body of water, bodies of water. They include the various ''marine mammals'' who dwell in oceans, as well as various freshwater species, such as the European otter. They are not a taxon and are not unified by any distinct biological grouping, but rather their dependence on and integral relation to aquatic ecosystems. The level of dependence on aquatic life varies greatly among species. Among freshwater taxa, the Amazonian manatee and river dolphins are completely aquatic and fully dependent on aquatic ecosystems. Semiaquatic freshwater taxa include the Baikal seal, which feeds underwater but rests, molts, and breeds on land; and the capybara and hippopotamus which are able to venture in and out of water in search of food. Mammal adaptation to an aquatic lifestyle vary considerably between species. River dolphins and manatees are both fully aquatic and therefore are completely tet ...

Amazon River Dolphin
The Amazon river dolphin (''Inia geoffrensis''), also known as the boto, bufeo or pink river dolphin, is a species of toothed whale Endemism, endemic to South America and is classified in the family Iniidae. Three subspecies are currently recognized: ''I. g. geoffrensis'' (Amazon river dolphin), ''I. g. boliviensis'' (Bolivian river dolphin) and ''I. g. humboldtiana'' (Orinoco river dolphin). The position of the Araguaian river dolphin (''I. araguaiaensis'') within the clade is still unclear. The three subspecies are distributed in the Amazon basin, the upper Madeira River in Bolivia, and the Orinoco basin, respectively. The Amazon river dolphin is the largest species of river dolphin, with many adult males reaching in weight, and in length. Adults acquire a pink color, more prominent, in males, giving it its nickname "pink river dolphin". Sexual dimorphism is very evident, with males measuring 16% longer and weighing 55% more than females. Like other toothed whales, they have a ...

Tursiops Truncatus 01
The bottlenose dolphin is a toothed whale in the genus ''Tursiops''. They are common, cosmopolitan distribution, cosmopolitan members of the family Delphinidae, the family of oceanic dolphins. molecular biology, Molecular studies show the genus contains three species: the common bottlenose dolphin (''Tursiops truncatus''), the Indo-Pacific bottlenose dolphin (''Tursiops aduncus''), and Tamanend's bottlenose dolphin (''Tursiops erebennus''). Others, like the Burrunan dolphin (''Tursiops (aduncus) australis''), may be alternately considered their own species or be subspecies of ''T. aduncus''. Bottlenose dolphins inhabit warm and Temperateness, temperate seas worldwide, being found everywhere except for the Arctic Circle, Arctic and Antarctic Circle regions. Their name derives from the Latin ''tursio'' (dolphin) and ''truncatus'' for the truncated teeth (the type specimen was old and had worn down teeth; this is not a typical characteristic of most members of the species).

Poaching
Poaching is the illegal hunting or capturing of wild animals, usually associated with land use rights. Poaching was once performed by impoverished peasants for subsistence purposes and to supplement meager diets. It was set against the hunting privileges of nobility and territorial rulers. Since the 1980s, the term "poaching" has also been used to refer to the illegal harvesting of wild plants. In agricultural terms, the term 'poaching' is also applied to the loss of soils or grass by the damaging action of feet of livestock, which can affect availability of productive land, water pollution through increased runoff and welfare issues for cattle. Stealing livestock, as in cattle raiding, classifies as theft rather than poaching. The United Nations' Sustainable Development Goal 15 enshrines the sustainable use of all wildlife. It targets the taking of action on dealing with poaching and trafficking of protected species of flora and fauna to ensure their availability for present ...

Platypus
The platypus (''Ornithorhynchus anatinus''), sometimes referred to as the duck-billed platypus, is a semiaquatic, egg-laying mammal endemic to eastern Australia, including Tasmania. The platypus is the sole living representative or monotypic taxon of its family Ornithorhynchidae and genus ''Ornithorhynchus'', though a number of related species appear in the fossil record. Together with the four species of echidna, it is one of the five extant species of monotremes, mammals that lay eggs instead of giving birth to live young. Like other monotremes, the platypus has a sense of electrolocation, which it uses to detect prey in cloudy water. It is one of the few species of venomous mammals, as the male platypus has a spur on the hind foot that delivers an extremely painful venom. The unusual appearance of this egg-laying, duck-billed, beaver-tailed, otter-footed mammal at first baffled European naturalists. In 1799, the first scientists to examine a preserved platypus bod ...

Capybara
The capybara or greater capybara (''Hydrochoerus hydrochaeris'') is the largest living rodent, native to South America. It is a member of the genus '' Hydrochoerus''. The only other extant member is the lesser capybara (''Hydrochoerus isthmius''). Its close relatives include guinea pigs and rock cavies, and it is more distantly related to the agouti, the chinchilla, and the nutria. The capybara inhabits savannas and dense forests, and lives near bodies of water. It is a highly social species and can be found in groups as large as one hundred individuals, but usually live in groups of 10–20 individuals. The capybara is hunted for its meat and hide and also for grease from its thick fatty skin. Etymology Its common name is derived from Tupi , a complex agglutination of (leaf) + (slender) + (eat) + (a suffix for agent nouns), meaning "one who eats slender leaves", or "grass-eater". The genus name, ''hydrochoerus'', comes from Greek (' "water") and (' "pig, hog") an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

North American River Otter
The North American river otter (''Lontra canadensis''), also known as the northern river otter and river otter, is a semiaquatic mammal that endemism, lives only on the North American continent throughout most of Canada, along the coasts of the United States and its inland waterways. An adult North American river otter can weigh between . The river otter is protected and insulated by a thick, water-repellent coat of fur. The North American river otter, a member of the subfamily Lutrinae in the weasel family (Mustelidae), is equally versatile in the water and on land. It establishes a burrow close to the water's edge in river, lake, swamp, coastal shoreline, tidal flat, or estuary ecosystems. The den typically has many tunnel openings, one of which generally allows the otter to enter and exit the body of water. Female North American river otters give birth in these burrows, producing litters of one to six young. North American river otters, like most predators, prey upon the most ...

Duisburg Zoo
The Duisburg Zoo, founded on 12 May 1934, is one of the largest zoological gardens in Germany. It is especially well known for its dolphinarium and, since 1994, for breeding koalas. Far less well known are the breeding successes in other areas, for example, with fossas (carnivorous mammals from Madagascar) and red river hogs. The zoo is located in the northern part of the Duisburg urban forest on the border with Mülheim on the Ruhr. Federal highway A 3 divides the zoo into western and an eastern parts, which are joined by a leafy country bridge. The highway is scarcely noticeable to the visitors. History The Duisburg Zoo was founded in 1934 as the ''Duisburg-Hamborner Tierpark am Kaiserberg''. In 1936, the zoo began to grow from a small animal park with its first (loaned) elephant. With the beginning of World War II in 1939, the zoo had to be closed. Only in 1946 was the zoo re-opened with animals loaned from the Hellabrunn Zoo in Munich. In 1952, the zoo could register t ...

North American Beaver
The North American beaver (''Castor canadensis'') is one of two Extant taxon, extant beaver species, along with the Eurasian beaver (''Castor fiber''). It is native to North America and has been introduced in South America (Patagonia) and Europe (primarily Finland and Karelia). The North American beaver is one of the national symbols of Canada and the official state mammal of Oregon and New York (state), New York. North American (Canadian) beavers are widespread across the continental United States, Canada, southern Alaska, and some parts of northern Mexico. In Canada and the United States, the North American beaver is often referred to simply as "beaver", although this can cause some confusion because another distantly related rodent, ''Aplodontia rufa'', is often called the "mountain beaver". Other vernacular names, including American beaver and Canadian beaver, distinguish this species from the other Extant taxon, extant beaver species, ''Eurasian beaver, Castor fiber'', which ...
