Dugong (Dugong dugon) 
&amp;#8230; inhabits shallow marine waters from East Africa to Vanuatu, with the largest populations found in the northern waters of Australia and in the Arabian Gulf.  Dugongs are herbivorous. They use their flexible upper lip to rip up entire seagrass plants, their preferred food. If the entire plant cannot be uprooted, they rip off leaves. Their grazing leaves distinctive furrows in the seagrass beds that can be detected from the surface.
