Abstract
Scientists recognized seven living species of sea turtles globally, which are grouped into six genera under two families. India's coastline is home to five species of sea turtles; olive ridley turtle (Lepidochelysolivacea), green turtle (Chelonia mydas), hawksbill turtle (Eretmochelys imbricata), loggerhead turtle (Caretta caretta), and leatherback turtle (Dermochelys coriacea). Unfortunately, their population is declining worldwide due to over-exploitation, pollution, habitat degradation, vessel hits, incidental catch, etc. Tamil Nadu and Orissa coasts play vital roles as the major marine habitats for sea turtles in India. Allfive species of sea turtles were recorded from the Tamil Nadu region. Andhra Pradesh and Tamil Nadu coasts serve as migratory pathways for olive ridleys, while Orissa's Gahirmatha stands as the world's largest rookery. Schedule I of the Indian Wildlife (Protection) Act 1972 safeguards all five sea turtle species, but conservation efforts must intensify emphasizing stakeholder involvement and alternative livelihoods.Turtle Excluder Devices (TEDs) serve as a successful method for mitigating trawling-related mortality in sea turtles.The widespread adoption of TEDs in trawl fisheries, coupled with governmental oversight and enforcement of TED regulations, is crucial forsuccessfully implementing these regulations (Boopendranathet al., 2006). Identification of sea turtle species in Indian waters relies on criteria including carapace lengths, costal scutes, prefrontal scales, and vertebral scutes' shapes.Clear photographs of the carapace and head are recommended in case of accuracy in identification.
