Centaurs

"Centaurs, so-called "beastfolk" (one of many placed under that umbrella term) are... they're just weird. I apologize, I know my editor's going to hunt me down for leaving this in, but by the elements, they are strange. They basically have the upper-torso of a human, combined with the entire rest of a horse? How did that happen? Why did it happen? How does anyone else have sex with one? I've never seen a naked centaur, but I can't imagine they have genitals like anyone else. Anyway, they're probably not actually related to horses or humans. Aglington researchers describe it as "convergent evolution" or something like that I don't know. (Seriously, Vincent, make sure you... I dunno, fix this section before you send this off to the publishers. Don't want to offend any centaur readers)"

Physical Traits
Centaurs could fairly accurately be described as some sort of half-human, half-horse people. From the waist up, a centaur is basically exactly like a human in appearance, perhaps save they ears, which may occasionally more closely resemble a horse's. From the waist-down, however, they are almost literally a horse, from the shape of their body, to they hooves on their feet. Centaurs tend to range from 7'2 at their shortest, to 9'0 at the tallest. Centaur skin tends to be either brown or tan.

When it comes to hair, the top half of a centaur is usually hairless, save the top of their head. The "horse half" is usually covered completely in very short, wiry fur, with a longer mane extending from the top of the "human half's" spine to the tip of the tail.

Diet
Centaurs are typically vegetarians.

Lifespan
Centaurs typically live around 100 years.

Reproduction
Centaurs give live birth after a period of pregnancy that typically lasts 11 months. Centaurs generally only give birth to one infant per pregnancy. Centaur infants are and oddity, in that their "horse half" is fully capable of moving shortly after birth, despite the "human half" not being fully capable of much thought.

Populations
Due to their vastly different morphology from other races, Centaurs typically find it difficult to live in the confines of most large cities or towns. Some are willing to deal with the difficulties, of course, but many more choose simply to wander the plains or forests and live off the land. There are even tales of human tribes with war bands that consist of a human archer or swordsman riding atop the back of a heavy shield-wielding centaur.
