Answer: D
Notes:

Dugong (Dugong dugon) is the only herbivorous mammal that is strictly marine and the only member of the Order Sirenia found in India.  

  • Dugongs are restricted to coastal shallow marine habitats and grazes on the sea grass meadows in coastal waters and are therefore called as “Sea Cows”.  
  • In India, it is one of the most seriously endangered species of large mammals.  
  • Dugongs are vulnerable to anthropogenic pressures as they are solely dependent on sea grasses in coastal areas, which now have been seriously damaged by mining, trawling etc.  
  • Dugongs have also been hunted for their meat, oil, hides, bones and teeth.
