Lucky is our Painted Turtle at the Museum. He’s an aquatic turtle, so he lives in the water. In the winter, Painted Turtles do something called brumation, which is a period of dormancy, similar to hibernation. During brumation, these turtles aren’t breathing through their lungs. Instead, they use their butts. This process is called cloacal respiration. Wonders of Winter is presented by Bank of America.
