The dugong is a medium-sized marine mammal. It is one of four living species of the order Sirenia, which also includes three species of manatees. It is the only living representative of the once-diverse family Dugongidae; its closest modern relative, Steller's sea cow (Hydrodamalis gigas), was hunted to extinction in the 18th century. The dugong is the only strictly marine herbivorous mammal, as all species of manatee use fresh water to some degree.

Adults occur in steep outer reef, occasionally in deep lagoons and along channel walls, usually in current prone habitats and where there are abundant gorgonian and long sea-whip corals on which they lay and guard eggs. The species feeds on zooplankton. \nMost of the time, a fish's behavior depends on its species. From time to time it is possible to meet exceptions, like this specimen, a very curious character, not shy at all, who came back looking at the camera many times.\nTriton Bay, West Papua Province, Indonesia, \n3°54'52.0617 S 134°7'21.3867 E at 9m depth
