Green Sea Turtle
- Distribution:
- Found in tropical and subtropical waters across the Atlantic, Pacific, and Indian Oceans.
- Commonly nests on sandy beaches and feeds in shallow coastal waters, lagoons, and seagrass meadows.
- Features:
- The Green Sea Turtle (Chelonia mydas) is the largest hard-shelled sea turtle species in the world.
- The name “green” refers not to its carapace (which is olive to black) but to the green-colored fat beneath its shell.
- It plays a vital ecological role as a keystone species in tropical marine ecosystems, maintaining healthy seagrass beds and coral reefs.
- Spends nearly its entire life underwater, surfacing only to breathe or nest on beaches.
- Lifespan: Estimated 60–70 years.
- Natal Homing: Females return to the same beach where they hatched to lay eggs.
- Nesting occurs mainly at night, with 50–200 eggs per clutch.
- Ecological Importance:
- Acts as a keystone species by maintaining seagrass bed productivity, ensuring the stability of marine ecosystems.
- Supports nutrient cycling between marine and coastal ecosystems.
- Threats Faced:
- Coastal development, pollution, fishing net entanglement, climate change, and illegal egg collection.
- Rising sea surface temperatures affect nesting success and sex ratios.
- Conservation Status:
- IUCN Red List: Least Concern
- CITES: Appendix I – International trade prohibited.
- Wildlife (Protection) Act, 1972: Schedule I
