The dugong (Dugong dugon), is a seagrass-dependant marine mammal of tropical and subtropical coastal waters, with high genetic biodiversity value. It is the sole member of the genus Dugong, which is the only extant member of the Family Dugongidae (UNEP, 2002; Bryden et al. 1998). The Dugongidae shares the Order Sirenia with just three species ...

as sea cows, but the dugong is really the seagrass specialist. Seagrass is the dugong’s only source of food (Marsh et al., 2002), and a mature dugong can consume 30 to 40 kg in 1 day. A biological study found that the main contribution to the digesta (61.0 to 98.9%) in the stomach of a dugong came from pioneering seagrass species such as ...
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.
Consquently, dugongs can influence the amount of seagrass that is available in an ecosystem as well as the types of seagrass that are present. In general, heavy excavation grazing by dugongs tends to favor fast-growing seagrass species over slow-growing species. This means that the loss of dugongs from a seagrass ecosystem may alter
currence of the dugong in the waters below the above mentioned temperature, we shall investigate most carefully whether or not the animal belongs to species of cetacean genera Orcaella or Neophocaena. In March 1979, an animal belonging to the latter genus was misidentified by local people in western Kyushu as a dead dugong.
