About

About the species

• Dugong (Dugong dugon) is a sirenian species native to parts of the Indian littoral.
• Dugongs are cousins of manatees and share a similar plump appearance, but have a dolphin fluke-like tail.
• And unlike manatees, which use freshwater areas, the dugong is strictly a marine mammal.
• Commonly known as "sea cows," dugongs graze peacefully on sea grasses in shallow coastal waters of the Indian and western Pacific Oceans.
• Dugongs as a Schedule I animal under the Wildlife (Protection) Act, 1972.
• Declining population: The dugongs are on the verge of extinction.
  • In the Andaman and Nicobar Islands, their population is less than 100.
  • There are very few left in the Gulf of Mannar.
  • In the Gulf of Kutch, there are very few sporadic records.
  • They were present in Lakshadweep but now are locally extinct.

The plan

• The plan included to set up a dugong conservation reserve in the Gulf of Mannar, Palk Bay between India and Sri Lanka, for the conservation of the animals.
