Correct me if I'm wrong, but aren't turtles amphibians, and tortoises reptiles?
Tangentially related: In 2005 or so, I took a drive up to Antietam, for their 'Artillery Hell' weekend. I saw a very large turtle(?) cross the road in front of me at a speed I never would have believed, if I hadn't seen it.

All turtles and tortoises are reptiles.
