Mass nesting of sea turtles in Odisha, India
A rare natural phenomenon occurs when hundreds of thousands of female Olive Ridley turtles simultaneously emerge onto beaches to lay their eggs.
This occurs at several protected coastal sites, including the famous Gahirmatha Beach, and is called an arribada—a synchronized mass hatching. The turtles, guided by waves, stars, and magnetic fields, return to the exact spot where they hatched. Over the course of a single night, each female creates several holes and lays hundreds of eggs, forming dense colonies that transform the beach into a living, moving field of shells. Local services and volunteers protect the nests from predators and human interference, as only a few of the millions of eggs survive to adulthood.
