Only certain seagrass meadows are suitable for dugong consumption, due to the dugong's highly specialized diet. There is evidence that dugongs actively alter seagrass species compositions at local levels. Dugongs may search out deeper seagrass.

Oct 4, 2019 · Dugongs are strict herbivores that feed on seagrass, especially the Hydrocharitaceae and Potamogetonaceae family of seagrasses. They prefer seagrasses that are low in fiber content, high in nitrogen, and easily digestible. Their intestines are long and suitable for digesting seagrass, and their metabolism rate is low.
Dugongs are herbivores (graminivores) and primarily feed on seagrass. They will occasionally eat invertebrates such as jellyfish, sea squirts, and shellfish. Populations in Moreton Bay, Australia, feed on invertebrates such as polychaetes or marine algae. Diet Herbivore, Graminivore.
Diet and Feeding Behavior. Dugongs have a specialized diet that reflects their adaptation to life in shallow coastal waters. They are herbivores, feeding almost exclusively on seagrasses. Dugongs graze on a variety of seagrass species, preferring those that are higher in nutrient content.

Dugongs are particular about their diets, with certain "fields" of sea-grass cropped. Dugongs commonly are referred to as "sea cows" because their diet consists mainly of the leaves and roots of sea-grass. An adult eats about 30 kilograms of seagrass each day (EPA 2007). Unlike manatees, dugongs are exclusively benthic feeders.
