I have a turtle that my son found as a hatchling in Okeechobee, Fla. The game warden said he could keep one, she came back home to Ohio in a styrofoam cup 17 years ago. We keep her in a fish tank, she eats turtle pellets and an occasional goldfish (when they bug her)! We have named her Cujo. She is only about 6 inches long, and very fast on land. Any idea what type she might be?
