Diplopodia
Diplopodia is a congenital anomaly in tetrapods that involves duplication of elements of the foot on the hind limb. It comes from the Greek roots diplo = "double" and pod = "foot". Diplopodia is often found in conjunction with other structural abnormalities and can be lethal. It is more extreme than polydactyly, the presence of extra digits. ==Description== The affected leg usually has one foot that is in an approximately normal position.〔 The extra foot is composed of at least some metatarsal or tarsal bones and extra digits, though it is usually not complete.〔 The feet can be joined together, so that the limb appears to have one large foot,〔 or the extra foot can be joined to the limb separately, usually above the level of the other foot. Diplopodia affects one or both of the hind limbs.〔
