Dugongs are large marine mammals often called sea cows due to their herbivorous diet and slow, gentle nature. They are related to both manatees and—surprisingly—elephants. They live in warm coastal waters from East Africa to Australia, grazing on underwater grasses as their main food source.
Dugongs are found in warm coastal waters from the western Pacific Ocean to the eastern coast of Africa, [22] along an estimated 140,000 kilometres (87,000 mi) of coastline [31] between 26° and 27° to the north and south of the equator. [13]

The dugong's body is large with a cylindrical shape that tapers at both ends. It has thick, smooth skin that is a pale cream colour at birth, but darkens dorsally and laterally to brownish-to-dark-grey with age. The colour of a dugong can change due to the growth of algae on the skin. The body is sparsely covered in short hair, a common feature amo...
Dugongs are found in warm coastal waters from the western Pacific Ocean to the eastern coast of Africa, along an estimated 140000 km of coastline between 26° and 27° degrees to the north and south of the equator. Their historic range is believed to correspond to that of seagrasses from the Potamogetonaceae and Hydrocharitaceae families. The full si...
Dugongs are long lived, and the oldest recorded specimen reached age 73. They have few natural predators, although animals such as crocodiles, killer whales, and sharks pose a threat to the young, and a dugong has also been recorded to have died from trauma after being impaled by a stingray barb. A large number of infections and parasitic diseases ...
Dugongs have historically provided easy targets for hunters, who killed them for their meat, oil, skin, and bones. They are often considered as the inspiration for mermaids, and people around the world developed cultures around dugong hunting. In some areas it remains an animal of great significance, and a growing ecotourism industry around dugongs...
Dugong numbers have decreased in recent times. For a population to remain stable, 95 per cent of adults must survive the span of one year. The estimated percentage of females humans can kill without depleting the population is 1–2%. This number is reduced in areas where calving is minimal due to food shortages. Even in the best conditions a populat...

Masako Suzuki searched for signs of dugongs in the lines of missing seagrass in the Oura Bay in Henoko, Okinawa, until the barrier of orange buoys went up, preventing her from doing that. Dugongs — rare, gentle marine mammals that are close relatives of the manatee — eat in a vacuum-like manner, slurping seagrass from the ...
