How do animals that live in ponds and lakes differ from the rest?
How do these animals obtain oxygen in this environment?
Some animals, like fish, use specialized gills to extract dissolved oxygen from the water, while others, like frogs and turtles, have lungs and breathe air. Some aquatic insects and other invertebrates have simple respiratory systems that allow them to exchange gases in and out of their bodies directly through their skin or gills.
