Cereans are a sophisticated and cultured humanoid mammalian species, originally hailing from the planet Cerea in the Mid Rim. They have tall tapering heads, which houses large binary brains, enabling them to focus on many things at the same time. Aside from this unique feature, Cereans are physically similar to Humans, although they each posses two hearts, which supply extra blood circulation to support their brains.

Cerean males age more quickly than the females, who have similar lifespans to Humans. Thus, there are fewer males than females. Polygamous marriage are a necessity in order for the species to survive. Each male usually has one primary “bond-wife”, and between four and ten “honor-wives”.

Famous for their extraordinary thinking abilities, Cereans are often found among the ranks of the Jedi and they have a cultural tradition of meditating with special crystals which matches very well with the Jedi philosophies.
