Aquatic reptiles are a diverse group of reptiles that have adapted to life in water. This category includes species such as crocodiles, alligators, and sea turtles. They possess physical features like streamlined bodies, webbed feet, or flippers that help them swim efficiently in aquatic environments. These reptiles can be found in various habitats, including oceans, rivers, and lakes. They play important roles in their ecosystems, often serving as predators or scavengers. Aquatic reptiles are cold-blooded, relying on external temperatures to regulate their body heat, and they typically come to land to bask in the sun or lay eggs.
