Centaur

## Description

Centaurs vary greatly from continent to continent. The only known locations of Centaurs are on Seron and Nova Terra. They vary in appearance slightly based on their 'ethnic' groups, but generally have the following traits.

They stand 4 to 6 feet tall at the withers, with an additional 4 or so feet in height from their human forms. Their forms are roughly the same size as a typical human as well as a typical horse.

### Metan

Metan Centaurs are tan, their human half appearing similar to other Metan humans. Their horse forms appear to be akin to warmbloods, though slightly larger.

### Novaen

Novaen Centaurs are copper, their human half appearing similar to other Novaen humans. Their horse forms appear to be akin to hotbloods, but slightly larger. They also, on their human form, each have a mark that slightly resembles a horseshoe somewhere on their body. Each of these marks are slightly different.

### Flatlanders

Flatlander Centaurs appear very similarly to Metan Centaurs, however they have small horns protruding from their foreheads.

## Anatomy

The anatomy of Centaurs are very unique, given that they are a hybrid between humans and horses. Their respiration and circulation systems are similar to humans, but other organ systems are unique.

### Digestive System

#### Mouth

Centaur's mouths are similar to humans. They have 16 molars, 4 pre-molars, 4 canines, and 8 incisors. Their tongues are typically longer, relatively, than human tongues. Roughly 6 or 7 inches in length.

#### Esophagi

Centaurs have primary and secondary esophagi, the first leading to their first stomach, the second leading to their second stomach. Their first esophagus is roughly 10-12 inches long. Their second esophagus is about 4 inches long.

#### Stomachs

Centaurs have two stomachs. The first is located in their human abdomen, it can hold roughly 1-1.5 gallons. This stomach shakes violently, but does not hold any acid. The second stomach is located at the upper barrel of the horse-part. This stomach can hold roughly 4-6 gallons, and has a very slow-acting acid which dissolves materials at a daily rate. As a result of these, the stomachs tend to store food for a long period of time, passing on to the intestines when more energy is needed.

#### Intestines

The Intestines are large, roughly 300 feet in length. They extract proteins and nutrients from consumed foods. In contrast to the slow process in the stomachs, the intestines work at an extremely quick rate, usually processing a gallon of food in less than an hour.

### Reproductive System

#### Female

The Female reproductive system are, like much of the Centaur's internal organs, a hybrid between human and equine body parts.

They have a vaginal opening at the posterior of their horse half. This is roughly 7" by 5" and highly elastic. This leads to a womb which can hold up to 1 gallon in volume. This, in turn leads to the ovaries.

#### Male

The Male Reproductive Systems are 'retractable'. Typically the male reproductive organs are sheathed, and they are located in its loin. The testes are typically 3-4 inches in diameter. And when non-erect, the penis is roughly 20 inches long and 4 inches in diameter. When erect, it doubles in all dimensions typically.
