[15] Dugongs in Moreton Bay, Australia, are omnivorous, feeding on invertebrates such as polychaetes[84] or marine algae when the supply of their choice grasses decreases. For a population to remain stable, 95 percent of adults must survive the span of one year. The tropical Indo-Pacific region is the most diverse seagrass bioregion, hosting 24 known species.
