What is the difference between red eared sliders and aquatic turtles?

Red-eared sliders are a specific species of aquatic turtle known for their distinctive red markings behind their eyes. While all red-eared sliders are aquatic turtles, not all aquatic turtles are red-eared sliders; the term "aquatic turtles" encompasses a wide variety of species that live primarily in water, including painted turtles, snapping turtles, and sea turtles. Red-eared sliders are particularly popular as pets and are easily recognized by their flattened shells and webbed feet. In general, aquatic turtles may vary in size, habitat preferences, and dietary habits.
