Cosians were a species of sentient reptilian humanoids who had beaked mouths, four-fingered hands, eyes with lids that blinked upward instead of down, and a long tail that ended in a tuft of hair. Jedi Master Tera Sinube, a member of the Jedi Order during the Clone Wars, was a Cosian. Nu-Cosian species was a genetically-engineered subspecies of the Cosians.
