Cerean (Earth-2042)

Cereans are a sophisticated and cultured humanoid mammalian sentient species hailing from the planet Cerea in the Mid Rim. They are famed 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. Aside from this unique feature, Cereans are physically similar to Humans, although they each possess two hearts, which supply extra blood circulation to support their brains.
