The Ur-Quan eventually learned to harness nuclear energy, and used this technology to create vehicles capable of traveling through interplanetary space. They were solitary hunters who had to defeat their strong territorial nature, and the deep hatred between each other, to found a mighty technological culture. Either contradicting this account or referring to a later period, the Kohr-Ah characterize their early existence as "a world where one species is the dominant killer, one's only threat is one's brother, one's sister, anyone of one's species", suggesting a situation that hindered the development of civilization.


The Ur-Quan evolved on a harsh, hostile world outside the region of space mapped by the Chenjesu, competing for survival with a variety of physically-superior species (according to the Melnorme) before developing tools to cope with them. Ur-Quan individuals were instinctively fiercely territorial against each other and against most other species, which they either hunted as food or chased off as potential predators or rivals. Unlike many sentient species, the Ur-Quan were not social animals they were, instead, solitary hunters, with all of their very limited repertoire of social instincts relegated to the field of sex and reproduction. The Ur-Quan's most anterior body segment, or its head, possesses a plethora of sensory organs, giving their face a wide variety of horrific expressions. They have long, multisegmented bodies with four arms protruding from the frontal segment they also have clawed legs on the posterior section of their bodies, which they use for clinging to the ceiling, while the anterior legs are longer and can function as grippers and manipulators. The Ur-Quan originally resembled externally a brown, 10-meter-long and 2-meter-thick variation of the predatory caterpillars native to Earth's Hawaiian Islands. For details on the separate cultural paths taken by the Kzer-Za and Kohr-Ah, see the relevant articles. This article is about the Ur-Quan species as a whole, including their development before the formal creation of the Kzer-Za and Kohr-Ah subraces. The Ur-Quan as we know them today are divided into two subspecies, the Ur-Quan Kzer-Za and the Ur-Quan Kohr-Ah, which form separate cultural and political units and are thus treated in separate articles.

Until their recent defeat by the New Alliance of Free Stars they were the dominant force in our galaxy, and countless sentient races' development have been halted by enslavement or genocide at their hands. The Ur-Quan are one of the oldest species known to the Alliance and are by far the greatest political and military power known to the galaxy for the past twenty millennia. See Ur-Quan Kzer-Za and Ur-Quan Kohr-Ah for more specific information on the two modern subspecies.
