Sea turtles are a type of marine reptile that lives in the ocean. They have streamlined shells and flippers, which allow them to swim quickly through the water. There are seven different species of sea turtles, including the green sea turtle, loggerhead sea turtle, Kemp's ridley sea turtle, olive Ridley sea turtle, hawksbill sea turtle, and leatherback sea turtle. These animals are known for their long lifespan and their ability to migrate across vast distances in the ocean. They feed on a variety of marine organisms such as jellyfish, sponges, crustaceans, and mollusks. Sea turtles play an important role in maintaining the health of coral reef ecosystems by controlling the growth of sea grasses. Sadly, many species of sea turtles are endangered due to human activities such as pollution, overfishing, and habitat destruction.
