Considered something of a headstrong species, they are independent and capable - yet prone to biting off more than they can chew. A hardy species that can take a great deal of stress, both inner and outer, xenobiologists have varyingly tried to tie this trait to different strands in the Zabrak genetic makeup, but it seems every few years another one comes along that disproves the one before it.
Their culture is nominally broken into eight major colonies, and each Zabrak is said by Iridonian law to belong to one of them. However this is often muddied by the interbreeding brought about by their great travels across the galaxy, and today it is not uncommon to find a Zabrak who claims membership in as many as five of the different colonies.
