A manatee relative (sirenian) that is entirely marine. Dugongs have forked tails, and tusks are found in males.

Dugongs (Dugong dugon) are the smallest members of the order Sirenia (which also includes the manatees and Steller's Sea Cow), with adults generally growing to less than 3 meters long. The name dugong originated from the Malay language duyung meaning lady of the sea or mermaid. They inhabit shallow waters in the Indo-Pacific, and feed on sea grass.
