The painted turtle is the most abundant turtle in North America. Four regional subspecies exist; although their ranges overlap and border populations interbreed, the subspecies differ in appearance, habitat and diet. The western painted turtle (C. picta bellii) is the most common and has the most colorful shell, featuring a red pattern on the plastron.
