DUGONG

Dugong is a medium sized marine mammal.It is one of four living species of the order Sirenia, which also includes three species of manatees.It is the only living representative of the once diverse family dugongidae its closest modern relative, Steller’s sea cow, was hunted to extinction in the 18th century. The dugong is the only strictly marine herbivorous mammal.
The Dugong’s body is large with a cylindrical shape that tapers at both ends, The tail’s flukes and flipper are similar to those of dolphins, and adult lenght rarely exceeds 3 metres. An individual this long is expected to weight around 420 kilograms. Weight in adult is typically more than 250 kilograms and less than 900 kilograms
The Dugong mainly lived in East africa, South Asia, Southern Pacific Outside Of Australia, Northern Pacific and Australia.Dugongs, along with other sirenians, are referred to as “Sea Cows’ because their diet consists mainly of sea grass.When eating they ingest the whole plant, including the roots, althought when this is impossible they will feed on just the leaves.
A Dugong reaches sexual maturity between the age of eight and eighteen, older than most of other mammal.The way that females know how a male has reached sexual maturity is by the eruption of tusks in the male since tusks erupt in males when testosterone levels reach a high enough level.
And thats all about Dugong
