Besalisks were a sentient species of humanoids with four arms. The superior arms dominated over the inferior ones. They could average in height between 1.88 and 2.36 meters and had green, orange, or brown colored skin. Their large hands and feet both ended in four digits and large brown nails. Besalisks were thick-set, and could have bloated stomachs. Besalisks also possessed a bony, three-pronged headcrest and an inflatable wattle. They had wide mouths, and some Besalisks had large, pudgy lips, though not all. Besalisks could sport black or brown hair on both their faces and their heads and could have brown, orange, or yellow eyes. At least one Besalisk was known to be Force-sensitive.

Society and culture
Besalisks were known to be industrious and hardworking. A Besalisk saying was “If your neighbors trouble you, send your rodents to their nest.”
