Dugong skeleton displayed at Philippine National Museum. Dugongidae's body weight ranges from 217 to 307 kg for juveniles, 334 to 424 kg for subadults, and 435 to 568.5 kg for adults. Oral temperatures for individual dugongs is determined from 24° to 34.2 °C. Heart rate readings are from 40 to 96 bpm and vary between individual dugongs.
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.
[30] [32] Unlike manatees, the dugong lacks nails on its flippers, which are only 15% of a dugong's body length. [33] Manatees generally glide at speeds of 8 kilometres per hour (5 mph), but can reach speeds of 24 kilometres per hour (15 mph) in short bursts. [ 34 ]
Paenungulata (from Latin paene "almost" + ungulātus "having hoofs") is a clade of "sub-ungulates", which groups three extant mammal orders: Proboscidea (including elephants), Sirenia (sea cows, including dugongs and manatees), and Hyracoidea . At least two more possible orders are known only as fossils, namely Embrithopoda and Desmostylia. [a]

The ultimate goal is for every animal rescued by TMMC to be released back to the ocean with a second chance at life. Since 1975, the center has rescued over 24,000 marine mammals, [2] mostly California sea lions, northern elephant seals and Pacific harbor seals. The center can have upwards of 275 animals at the hospital at one time.
Dugongs. 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. Family: Dugongidae. Genus: Dugong. Dugong, Dugong dugon VU
The focal point of her research has been the biology of dugongs, with particular foci in the areas of population ecology, history, reproduction, diet, and movements.
