Dugongs are part of the Sirenia order of placental mammals which comprises modern "sea cows" (manatees as well as dugongs) and their extinct relatives. Sirenia are the only extant herbivorous marine mammals and the only group of herbivorous mammals to have become completely aquatic.
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.
May 27, 2024 · Dugongs are considered herbivores because they primarily feed on a diet of seagrass and algae at the bottom of the coastal beds. Less commonly, they will consume invertebrates either as a supplement while foraging for grass or as a replacement when other foods cannot be found.

The dugong, like all sea cows, is herbivorous. It primarily grazes on sea grasses and therefore spends most of its time in sea grass beds. Unlike the closely related manatees, the dugong never enters freshwater and is therefore the only exclusively marine mammal that is herbivorous.
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 primarily herbivorous, grazing on up to 30kg of seagrass a day. They eat both day and night, locating their food with the help of coarse, sensitive bristles on their upper lip. These large creatures are found in warm water around coastlines, both north and south of the equator.
