The correct answer is option 1, which is mass egg-laying by sea turtles.
Rushikulya and Gahirmatha are two places in India that have gained recognition for a specific reason. In this case, it is mass egg-laying by sea turtles. Sea turtles are known to come ashore on certain beaches around the world to lay their eggs. Rushikulya and Gahirmatha have become popular destinations for this phenomenon.
Sea turtles are fascinating creatures that have a unique life cycle. After reaching sexual maturity, they return to the same beaches where they were born to lay their eggs. These beaches provide the ideal conditions for the eggs to hatch and for the baby turtles to make their way to the ocean.
Mass egg-laying by sea turtles is a significant event because it highlights the importance of conserving these fragile creatures and their habitats. It also provides an opportunity for researchers, nature enthusiasts, and tourists to witness this natural wonder.
In contrast to the other options, captive breeding of Gharials, pre-historic cave paintings, and uranium deposits do not align with the specific scenario mentioned in the question. Therefore, option 1, mass egg-laying by sea turtles, is the correct answer.
