A first-of-its-kind initiative began satellite-tagging Olive Ridley sea turtles on Chennai beaches. Two nesting turtles were satellite-tagged and released. The 2025-2027 project by the Wildlife Institute of India and the Advanced Institute for Wildlife Conservation, Vandalur, covers the Chennai coast and Cauvery delta, aiming to satellite-tag 10 turtles and flipper-tag 1,000.
