Bravaisians were a humanoid sentient species that stood at a diminutive height, with blue, leathery skin and two arms that ended in four digits. They had snouts that faded to pink at their end. These snouts contained a prehensile tongue as dexterous as their fingers. Bravaisians would alternate between using their fingers and their tongues. Some Bravaisians, such as Sonsigo, had hair growing from the back of their heads.

Bravaisians were nocturnal due to the intense heat and lack of life on Bravais during the day. As a result, they had small eyes that could easily be overwhelmed by light. For this reason, most members of the species were rarely seen without protective goggles while offworld. Some even had their eyes surgically removed to combat this problem.

Bravaisians could make a squawking sound if disturbed. Due to them being nocturnal, Bravaisians viewed other species’ insistence on doing business during daylight hours with a mix of pity and contempt.

Bravaisians evolved from pack hunters, that used their tough, flexible snouts to dig through soil and dirt in order to find their prey, which were tubers and nests of insects. They would then suck up these with their long muscular tongues.
