Nov 15, 2024 · Dugongs range in length from about 2.2 to 3.4 metres (7 to 11 feet) and weigh 230 to 420 kg (500 to 925 pounds). As with whales and dolphins, the dugong has a tapered body that ends in a deeply notched tail, or fluke.
Sirenian bones are exceptionally dense, most of them lacking marrow. This adaptation is thought to help maintain neutral buoyancy. Manatees and dugongs differ in a number of traits besides the shape of the tail. Manatees lack incisor teeth, but incisors do occur in dugongs, erupting as tusks in the males.
