The green frog, pictured above, is pretty common in the eastern half of North America. Its range includes the eastern half of Minnesota. They can be found in most permanent wetland habitats, such as ponds, lakes, Rivers, streams, and swamps. Like most frogs they have excellent hearing which helps them to avoid predators. The large circle, which is visible on the side of the head, is called a tympanum. The tympanum is the frogs eardrum and transmits vibrations to the frogs inner ear which is located inside the frogs body.
