Dugongs

Dugongs and can be pronounced as Do-Gongos, some people call it the sea camel or sea pigs,The dugong (Dugong dugon) is the only herbivorous mammal that is strictly marine, and is the only extant species in the Family Dugongidae. It is listed as vulnerable to extinction at a global scale by The World Conservation Union (IUCN). The dugong has a large range that spans some 37 countries and territories and includes tropical and subtropical coastal and island waters from East Africa to Vanuatu, between about 26° north and south of the Equator. It lives in the warm water near the coasts or lakes and they prefer the shallow waters, They eat grass and it considered as a very rare aquatic mammals and has been listed in the IUCN Red List  & they have the same ancient ancestors as the elephant.
Dugongs are seagrass specialists and frequent coastal waters. Major concentrations of dugongs tend to occur in wide shallow protected bays, wide shallow mangrove channels and in the lee of large inshore islands. Dugongs are also regularly observed in deeper water farther offshore in areas where the continental shelf is wide, shallow and protected. The dugong’s fecundity is very sensitive to the availability of its seagrass food. When dugongs do not have enough to eat they delay breeding, making habitat conservation a critical issue.
Dugongs are vulnerable to anthropogenic influences because of their life history and their dependence on seagrasses that are restricted to coastal habitats and 1 Executive Summary are often under pressure from human activities.
The Dugongs in Marsa Alam weights around 300-500 kg and 2-3 meters long and the they live around 50 years.
You can find the Dugongs in Abu Dabbab area bay, 30 km north of Marsa Alam City.
