Quick answer
Dugongs feed on seagrasses and algae, adjusting with season, age, and what is abundant in Shallow coastal waters, bays, and seagrass meadows of the Indo-Pacific. That label is a preferred pattern, not every item an individual might sample.

Dugong diet overview
Dugongs (Dugong dugon) are best summarised as Herbivore — seagrasses and algae. Anatomy and habitat (Shallow coastal waters, bays, and seagrass meadows of the Indo-Pacific) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How dugongs find food
Energy-rich foods are prioritised when available; lean seasons force broader diets or longer travel. Young animals may eat different items or receive food from parents.
Dugong role in the food web
As herbivores shaping plants and seeds, dugongs move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild dugongs. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
Seagrass gardener
Dugongs crop seagrass with stiff bristled lips, preferring certain species and leaving tell-tale feeding trails across meadows. Healthy dugong populations indicate productive seagrass ecosystems that also support fish, turtles, and coastal fisheries.
Sirenian relatives
Dugongs are the only living sirenians in the Indo-Pacific; manatees occupy the Atlantic. Their closest land relatives are elephants. Females produce a single calf after a 13–14 month gestation, nursing for up to 18 months — a slow reproductive rate that limits recovery from population declines.

What is the scientific name of the dugong?
Dugong dugon — used in research and conservation listings for dugongs.
Where do dugongs live?
They are associated with Shallow coastal waters, bays, and seagrass meadows of the Indo-Pacific. Local presence depends on food, cover, and human land use.
