The Yunnan box turtle is a rare species of freshwater turtle from China. It has a special hinged shell that allows it to completely close its head, legs, and tail for protection from enemies.
The Yunnan box turtle differs from related species in its special shell structure and limited distribution in the mountains of Yunnan. It is important for nature as a participant in food chains in freshwater bodies and an indicator of ecosystem health.
Immature form that undergoes metamorphosis before adulthood.
