Aquatic turtles are reptiles that primarily live in water, including rivers, lakes, and ponds. They have streamlined bodies and webbed feet or flippers, which help them swim efficiently. Common species include the painted turtle and the red-eared slider. These turtles are known for their hard shells, which protect them from predators. Aquatic turtles are omnivorous, feeding on a diet of plants, insects, and small fish. They are ectothermic, meaning their body temperature is regulated by their environment. Many species bask in the sun to warm up and can hold their breath underwater for extended periods while foraging or hiding from threats.
