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. Respiration rate during the out-of-water phase is from 1 to 33.
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.
The body parts of dugongs are used as medicinal remedies across the Indian Ocean. [39] Manatees in Cuba have faced poaching, entanglement and pollution. The area has some of the most extensive and best manatee habitat in the Caribbean, but the population has been unable to thrive there. [71]
Articles relating to the Dugongidae, a family in the order of Sirenia. The family has one surviving species , the dugong ( Dugong dugon ), one recently extinct species, Steller's sea cow ( Hydrodamalis gigas ), and a number of extinct genera known from fossil records.
By the time the Eocene drew to a close, came the appearance of the Dugongidae; sirenians had acquired their familiar fully aquatic streamlined body with flipper-like front legs with no hind limbs, powerful tail with horizontal caudal fin, with up and down movements which move them through the water, like cetaceans.
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 ().
It is the smallest known post-Eocene sirenian, with body lengths of about 2 meters and weighing about 150 kg. Newborn nanosirens may have weighed only 6.8 kg. Its small size gave rise to the naming of its genus as Nanosiren, from the Greek for a "dwarf siren". These mammals were of shallow draft and possessed small, conical tusks, suggesting ...
It is an early member of the family Dugongidae, which includes the extant dugong. Fossils have been found from Egypt , India , and Madagascar . Eotheroides was first described by Richard Owen in 1875 under the name Eotherium , which was replaced by the current name in 1899.
