The Japanese pond turtle is a small freshwater turtle with an oval shell. It lives in rivers, ponds, and swamps of Japan and spends most of its time in the water.
The Japanese pond turtle differs from close species by the net-like pattern on the shell and yellow stripes on the head. It is important for nature because it helps maintain the cleanliness of water bodies by eating algae and small animals.
Immature form that undergoes metamorphosis before adulthood.
