A centaur is a creature from Greek mythology, generally portrayed as a being with the full body of a large horse with the upper torso, arms and head of a human located approximately where the horse's head should have been. They were considered barbarians, but certain centaurs, notably Chiron were viewed as divinely wise. Some earlier images of centaurs show them with four human legs rather than the horse body.
There are few mythological tales of female centaurs, this may be because the myths make them out to be all males, but biologically it could be due to the fact that female centaurs may lack upper body breasts (despite how they are often shown in art) and so mistaken for males. There are other centaurs found in different cultures. In anthropomorphic or furry fandom, there are many variant types of centaur, often with greater or lesser amounts of animalistic appearance. For instance some have the upper bodies of humans but the lower bodies of foxes, lions or even spiders. In this case, centaur becomes a more generalized term referring to a usually hexapedal creature possesed (usually) of two manipulative appendages and four locomotive limbs, though even this can vary significantly, such as in the case of a spider centaur, which could have eight lower limbs. Some are wholly animal in appearance, these usually go by the generic name taur usually having the upper body of an anthro creature and the lower body of the same. A foxtaur, for example, would have the upper body of an anthro fox as well as four lower fox appendages.
