The Zeetsa are a sophisticated and cultured humanoid mammalian species that hail from the planet Gorvin in the Alpha Quadrant. They have tall tapering heads, which housed large binary brains, enabling them to focus on many things at the same time. Aside from this unique feature, Zeetsa are physically similar to humans, although they possess an extra heart, which supply extra blood circulation to support their brains. Zeetsa males age more quickly than the females, who have similar lifespans to Humans. Thus, there are fewer males than females. Polygamous marriage is a necessity in order for the species to survive. Each male usually has one primary "bond-wife", and between four and ten "honor-wives". Their enlarged skulls, extending up to twenty centimeters above their foreheads, house complex binary brains, they provide with sufficient blood by an extra heart in their heads. The binary structure of Zeetsa thinking helped them to ponder two sides of an issue at once. It also enables them to process information and solve problems rapidly. Because of their thoughtful nature, they tended to be calm, rational, and analytical, preferring peaceful philosophies and a lifestyle which worked in harmony with nature. Though the quick-thinking Zeetsa had equally quick reflexes, they were commonly not as well coordinated as Humans. Because of the weight of their enlarged skulls, Zeetsa often had back problems.
