The dugong (/ ˈ d (j) uː ɡ ɒ ŋ /; 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.
Manatee rehabilitation for diseases like cold stress syndrome is possible through the support of veterinary staff, zookeepers, researchers, and volunteers in the field. The number of manatees needing intervention is likely to rise as the number of warm water habitats decrease due to declining spring discharges and retirement of power plants. [98]
The manatee is unusual among mammals in having just six cervical vertebrae, [11] a number that may be due to mutations in the homeotic genes. [12] All other mammals have seven cervical vertebrae, [13] other than the two-toed and three-toed sloths. Like the horse, the manatee has a simple stomach, but a large cecum, in which it can digest tough ...
This animal is known for its unique appearance, which includes having a pig-like snout. Despite their appearance, they are great diggers that can dig a two foot hole in roughly 15 seconds using ...
West Indian manatee. Sirenia is an order of fully aquatic, herbivorous mammals that inhabit rivers, estuaries, coastal marine waters, swamps, and marine wetlands. All four species are endangered. They evolved about 50 million years ago, and their closest living relatives are elephants. The manatees are the only extant afrotherians in the Americas.
The West Indian manatee has a prehensile snout, like their relative the elephant, for grabbing vegetation and bringing it into their mouths. Manatees have six to eight molariform teeth in each jaw quadrant. These molariform teeth are generated at the back of the mouth and slowly migrate towards the front of the mouth, at a rate of 1–2 mm per ...
A humpback whale (Megaptera novaeangliae) A leopard seal (Hydrurga leptonyx). Marine mammals are mammals that rely on marine (saltwater) ecosystems for their existence. They include animals such as cetaceans (whales, dolphins and porpoises), pinnipeds (seals, sea lions and walruses), sirenians (manatees and dugongs), sea otters and polar bears.
Embrithopods were rhinoceros-like herbivorous mammals with plantigrade feet, and desmostylians were hippopotamus-like amphibious animals. Their walking posture and diet have been the subject of speculation, but tooth wear indicates that desmostylians browsed on terrestrial plants and had a posture similar to other large hoofed mammals.
