What is the cloacal opening of a turtle?

The cloacal opening is the anus. Aquatic turtles hibernate in the water during the winter months. Their body functions slow and the anus widens to allow water to circulate into the opening. The opening is similar to the gills of a fish. As water circulates through the opening oxygen is absorbed by the many capilaries located in the cloacal opening.
