Snivvians were mammalian humanoids distinguishable by their large nostrils and their protruding lower jaws, with two small tusks. Their hair color varied between brown and black, but they possessed a larger variation of skin and eye colors. They were capable of speaking Galactic Basic but also communicated via snorting through their nostrils.

Snivvians were native to the planet Cadomai Prime. The winters on their homeworld were long, harsh, and difficult to survive. During this time, the Snivvians spent their time in underground caverns in artistic pursuits. Many of the species escaped the icy tundras to become gangsters or bounty hunters offworld.
