Dugongs are large marine mammals that graze on seagrasses along coastlines from East Africa to Australia. They can stay underwater for up to six minutes and breathe either by fully surfacing or standing on their tails. Dugongs spend most of their time alone or in small groups but sometimes gather in large herds, and mothers care for calves for around 18 months. Although now protected, dugongs were historically hunted for their meat and other products, and their populations remain vulnerable.

Dugong fact sheet
1. Dugong Fact Sheet:
These enormous vegetarians can be found in warm coastal waters from East
Africa to Australia, including the Red Sea, Indian Ocean, and Pacific.
Dugongs are related to manatees and are similar in appearance and
behavior— though the dugong's tail is fluked like a whale's. Both are related
to the elephant, although the giant land animal is not at all similar in
appearance or behavior.
Dugongs graze on underwater grasses day and night, rooting for them with their bristled, sensitive snouts and
chomping them with their rough lips.
These mammals can stay underwater for six minutes before surfacing. They sometimes breathe by "standing" on
their tail with their heads above water.
Dugongs spend much of their time alone or in pairs, though they are sometimes seen gathered in large herds of a
hundred animals.
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 close to its mother for about 18 months, sometimes catching a ride on
her broad back.
These languid animals make an easy target for coastal hunters, and they were long sought for their meat, oil, skin,
bones, and teeth. Dugongs are now legally protected throughout their range, but their populations are still in a
tenuous state.
Some believe that dugongs were the inspiration for ancient seafaring tales of mermaids and sirens.
