How big are dugongs?
Dugongs are up to 3m in length and weigh around 500kg
Where do they live?
The species’ range extends from the Red Sea, the Arabian Gulf and the east coast of Africa, through the west coast of India, to encompass much of the waters of south-east Asia to the northern edge of Australia. Unlike manatees, the dugong is an entirely saltwater-dwelling animal, the name being a corruption of the Malay duyung, meaning ‘lady of the sea’ or ‘mermaid’.

Can dugongs breathe underwater?
Dugongs must surface to breathe. Dugongs cannot hold their breath under water for very long so every three minutes or so a dugong has to swim to the surface to breathe.
Ahmed Shawky, environmental researcher for the technical office of the Egyptian Minister of the Environment, found they spent 16 per cent of the time surfacing.
Ahmed has been observing and working to understand declining numbers of dugongs since he discovered that no research had been conducted on the species since 1957
