Anatomy and Morphology
The dugong's body is large and fusiform, with thick, smooth skin that is a pale cream color at birth but darkens dorsally and laterally to a brownish to dark grey color with age. The body is sparsely covered in short hair, a common feature among sirenians which may allow for tactile interpretation of their environment. The dugong has paddle-like forelimbs which aid in movement and feeding, while its fluked tail provides locomotion through vertical movement. The teats are located just behind the forelimbs, similar to their location in elephants.
Dugongs are generally smaller than manatees (with the exception of the Amazonian Manatee), reaching an average adult length of 2.7 metres (8.9 ft) and weight of 250 to 300 kilograms (551 to 661 lb).
