Species (Earth-2356)

A species is a group of living organisms capable of interbreeding. The galaxy and its many planets are teeming with diverse species. Members of a species share a fixed set of observable biological characteristics. Some species are sentient, capable of intelligent thinking, while others are not. Species whose body plan resemble that of Humans are referred to as humanoid.

According to sentientologist Tem Eliss, most sentient species in the galaxy are about the same size, ranging in height between about half a meter to three meters.
