This lesson is about Sea Turtles which are different from Tortoise that we see in a zoo or a reptile park. There are seven species of sea turtles -out of which five are seen in India – the Olive Ridley, the Hawksbill, the Green Sea Turtle, the Loggerhead and the Leatherback. The turtles are huge and weigh between 35 kg and 700 kg. The largest sea turtle is the Leatherback which is 2.2m long and 700 kg in weight. Sea turtles come to the shore to lay their eggs. Except Olive Ridleys, other species have become rare in India. Mass Nesting or Arribada is a phenomenon that occurs in Odisha and other two places in the world where Olive Ridleys come ashore alone to lay their eggs.

Between January and March, female Olive Ridleys come ashore and haul (pull with force) using their front flippers onto the beach. They choose a spot away from the high tide and dig 45 cm into which they lay their eggs. They lay about 100 eggs at one time. After covering the nest with sand it returns to the sea. The eggs are left to incubate under the sun. People collect these eggs for eating. Jackals, domestic dogs and pigs eat the eggs. After escaping from the predators, the hatchlings (little ones) come out the egg shell with the help of egg-tooth. After they come out they make a dash into the sea.

Weighing less than 20 grams, many of these hatchlings fall prey to crabs or birds before they reach the sea. It is estimated that one in a thousand hatchlings become an adult. After swimming for years in the sea, the adult female returns to the same beach where they were born which is an unsolved mystery. Human activities have endangered the survival of sea turtles. Problems like pollution, dumping of plastics in to the ocean and the construction activities on nesting beaches endanger their survival. We have to tackle these problems to save the sea turtles.
