What are the names of small turtles?

Though many pet stores claim to have 'miniature turtles' while there is really no such thing. Most of the so called 'miniature' turtles are in fact baby sliders or cooters. Both of which can get to 10+ inches when fully grown. Sliders average size are: males- 7-9in; females- 8-12. And cooter females can get up to 16in. A good site to look at for care and other information on different turtle species and there captive care is Austins Turtle Page.
