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.
6 days ago · Dugong, marine mammal that inhabits the warm coastal waters of the Indian and Pacific Oceans, feeds on seagrasses, and is similar to the American manatee.
Reproduction and Conservation. Female dugongs have one calf after a yearlong pregnancy, and the mother helps her young reach the surface and take its first breath. A young dugong remains...
- Dugongs Are Also Called Sea Cows. Dugongs have very muscular cleft upper lips that stick out over their mouths. These bristled and ultra-sensitive snouts are very strong and allow dugongs to root around the ocean floor and grab seagrass.
- They are Closely Related to Elephants. There were once other Dugongidae species like dugongs in the oceans, like the Steller’s sea cow (Hydrodamalis gigas).
- You Can Guess a Dugong’s Age by Looking at the Rings on Its Tusks. The tusks of a dugong are actually just two elongated front teeth. These stick out from their mouths and have sharp, angled edges.
- Dugongs Can Live for a Very Long Time. When dugong babies are born, they are only around 3 or 4 feet long and weigh 44 to 77 pounds. That may not seem all that small, but a fully grown dugong can grow up to 10 feet long and weigh over 1,000 pounds!
The dugong is an aquatic mammal with thick, tough, and smooth skin. The skin color of newborn dugongs is pale cream, darkening as they age, becoming deep slate gray on the sides and dorsum. The body of the dugong is sparsely covered with hair, and the muzzle exhibits bristles.
The dugong is a gray/brown marine mammal with a torpedo-shaped body. They are considerably more streamlined in appearance than their rather rotund relative, the manatee. Dugongs also differ from their manatee cousins in the shape of their tails.

What does a dugong eat?
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.
