The Dugong (Dugong dugon) is the smallest member of the order of Sirenia. It derives its name from the Malay language, where duyung means "lady of the sea" or "mermaid". Their diet consists of sea grass (they are often called sea cows) on which they feed one to five meters below the surface and can grow up to three meters in length. Occasionally they feed on algae and crab. Dugongs are more strictly marine than manatees. Dungongs are listed as an endangered species. There are some excellent dugong movies on the internet here.
The Dugong, sea cow is listed as Vulnerable (VU), considered to be facing a high risk of extinction in the wild, on the IUCN Red List of Threatened Species
