Although they once covered all of the tropical South Pacific and Indian Oceans, remaining populations are greatly reduced. Groups of 10,000 or more are present on the Great Barrier Reef of Australia, at Shark Bay, and in Torres Strait south of New Guinea. Before 1970, it is thought that large populations were also present in Mozambique and coastal Kenya, but these have dwindled. Palau also has a small population. On January 22, 2003, after 70 years, an individual was found (weight 300 kg, length 2 m) off the coast of Tanzania. The Pacific Ocean (from the Latin name Mare Pacificum, peaceful sea, bestowed upon it by the Portuguese explorer Ferdinand Magellan) is the worlds largest body of water. ...

 Moreton Bay looking NE toward Moreton Island Moreton Bay, a large bay on the eastern coast of Australia, is one of many homes to the Dugong because it contains clean and clear water at the appropriate depth ranges and suitable food. Access to the sea for warmth is possible, although strong tidal currents affect the exact times and durations of each visit, the dugong return to the bay for protection from large sharks.

Dangers One example in Japan: the US and Japanese government want to build a new base on a coral reef close to Henoko, in Nago prefecture, Okinawa.
