The Orissa High Court has taken suo motu cognisance of the death of around 800 Olive Ridley sea turtles due to negligence by Odisha’s forest and fisheries departments.

Key Points

  • Features of Olive Ridley Turtles:
    • The Olive ridley turtles are the smallest and most abundant of all sea turtles found in the world.
    • These turtles are carnivores and get their name from their olive colored carapace.

  • Protection Status:
  • Habitat:
    • They are found in warm waters of the Pacific, Atlantic and Indian oceans.
    • The Odisha’s Gahirmatha Marine Sanctuary is known as the world’s largest rookery (colony of breeding animals) of sea turtles.
  • Arribada (Mass Nesting):
    • They are best known for their unique mass nesting called Arribada, where thousands of females come together on the same beach to lay eggs.
    • They lay their eggs over a period of five to seven days in conical nests about one and a half feet deep which they dig with their hind flippers.
  • Threats:
    • Marine pollution and waste
    • Human Consumption: They are extensively poached for their meat, shell and leather, and eggs.
    • Plastic Garbage: An ever-increasing debris of plastics, fishing nets, discarded nets, polythene and other garbage dumped by tourists and fishing workers.
    • Fishing Trawlers: Overexploitation of marine resources by use of trawlers often violates the rule to not fish 20 kilometres within a marine sanctuary.
      • There were injury marks on many dead turtles indicating they could have been trapped under trawls or gill nets.

Gahirmatha Marine Sanctuary

  • Gahirmatha is the mass nesting spot in Indian Ocean region and the only turtle sanctuary in Odisha.
  • It is the world’s largest nesting beach of Olive Ridley Sea Turtles.
  • Gahirmatha was declared a turtle sanctuary in 1997 by the Odisha government after considering its ecological importance and as part of efforts to save the sea turtles.
  • Gahirmatha Marine Sanctuary is one of the three parts of the Bhitarkanika National Park. The other two includes the area of Bhitarkanika National Park and the Bhitarkanika Wildlife Sanctuary.
