Dugongs
Dugongs are cousins of manatees and share a similar plump appearance, but have a dolphin fluke-like tail. And unlike manatees, which use freshwater areas, the dugong is strictly a marine mammal. Commonly known as "sea cows," dugongs graze peacefully on sea grasses in shallow coastal waters of the Indian and western Pacific Oceans.

Threats to dugongs

© Jürgen Freund / WWF
Dugongs are threatened by sea grass habitat loss or degradation because of coastal development or industrial activities that cause water pollution. If there is not enough sea grass to eat then the dugong does not breed normally. This makes the conservation of their shallow water marine habitat very important. They also often become victims of bycatch, the accidental entanglement in fishing nets.
