In the southwestern United States there are only dispersed populations. “Blanding's turtles have a hinged plastron to help protect them when they hide inside, snapping turtles are Ontario's largest turtle and midland painted turtles live 29-44 years in the wild on average, the longest recorded one in the wild lived to be 60!” About the Author: Andrew Philips.
