Cerean

Cereans are a spiritual and eco-conscious humanoid mammalian species originating from the planet Cerea in the Mid Rim. They are known throughout the galaxy for their extraordinary thinking abilities, made possible by large binary brains housed in tall tapering heads, enabling them to focus on many things at the same time. This allowed some Cerean force-sensitive scholars to explore both the dark as well as the light side of the force. Aside from this unique feature, Cereans are physically similar to Humans, although they each possess two hearts, which supplies extra blood circulation to support their brains. Cerean males age considerably faster than females, who are born at roughly twenty times the rate as males. To preserve the species, male Cerean Knights of the  Jedi Order  are often allowed to marry and reproduce with several females of the species.
