Definition of marine reptiles

Marine reptiles are reptiles that have adapted to life in the ocean or other saltwater environments. They are a diverse group of animals that evolved independently from marine mammals, such as whales and dolphins, and fish. Some examples of marine reptiles include sea turtles, marine iguanas, mosasaurs, plesiosaurs, and ichthyosaurs. These animals have a number of adaptations that allow them to thrive in the marine environment, such as streamlined bodies, flippers for swimming, and the ability to hold their breath for long periods of time underwater.
