For example, horses and pigs have many small contacts spread over the entire surface of the fetal membranes and this form of placenta is termed a ''diffuse placenta''. Ruminants have 15-120 button-like contact regions between the fetal membranes and the endometrium and this type of placenta is called a ''cotyledonary placenta''. Predatory species have chorionic villi arranged in a circular band around the fetus, called the "zona placenta".
