Thondi coast, located along the Palk Strait in Tamil Nadu, is home to lush seagrass meadows. These underwater ecosystems provide vital nursery and feeding grounds for a diverse array of marine species. Endangered marine species like dugongs and green turtles frequent the seagrass meadows for grazing and nesting. Additionally, seagrass plays a crucial role in coastal protection, nutrient cycling, and carbon sequestration. However, anthropogenic pressures pose threats to these ecologically significant ecosystems.
