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.

Better Choices at the Great Barrier Reef

For decades, the Great Barrier Reef has enjoyed World Heritage Status and been synonymous with diving, tourism and with Australia. But in June of this year, UNESCO threatened to downgrade the Great Barrier Reef to the World Heritage ‘In Danger’ list; a category populated predominantly by war-torn and developing nations. The final decision should be made in 2015.

Oval seagrass (Halophila ovalis) dugong food Palawan Philippines, 21 April 2010

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.
