The Herrera's Mexican mud turtle is a small freshwater turtle with a dark shell. It lives in eastern Mexico in rivers, ponds, and swamps.
This turtle differs from close species with a special shell structure with three keels and small size. It is important for nature because it eats carrion and small animals, helping to keep water bodies clean.
Immature form that undergoes metamorphosis before adulthood.
