Walking along the Ohio & Erie Canal Towpath this Summer I encountered a turtle that I had never seen in the wild before. Its Latin species name is geographica and both this and its common name “map turtle,” refer to the markings on the skin and shell.

Part of the difficulty in finding this turtle is that it prefers to live in large rivers and is very wary, diving into the water at the slightest disturbance. It prefers large bodies of water and areas with fallen trees and other debris for basking. These turtles are more often found in rivers than in lakes or ponds.

Northern Map Turtles are more carnivorous than most other water turtles. Adult females have wide heads and broad, flat crushing surfaces in their mouths which they use to feed on molluscs, their primary prey, as well as insects and crayfish.

It is not unusual to see these turtles walking around under the ice, for they are among the very last turtles to go into hibernation – if they go at all – and among the earliest to reappear in spring.

The female of this species attains a shell length of about 10 inches, while the male’s seldom exceeds five inches. These reptiles are found throughout the eastern half of the USA and northward into southern Canada. In addition to being called Map Turtles, they are also known as Sawback Turtles. Whatever you call it, it was awesome to see this reptile in the wild!
