there are leaf turtles which have been bred in small numbers of late,have seen cogwheels but not for a few years now,could be some out there still?Americans call the boxies turtles but to my way of thinking,although they like a swim and like good bit of mud etc they are way more of tortoise than a turtle?There are 3 toes,and the odd eastern and ornate,also an odd Gulf coast and florida box.Pretty sure there are no more diamond backs left now but you never know what is out there?
