Zurros served as a Falleen senator in the Galactic Republic representing Falleen during the Clone Wars; he was a male of that species.
Senator Zurros tried to manipulate both the Loyalists and the Separatists within the Senate. This changed when Count Dooku instructed Quinlan Vos to eliminate him on The Wheel in 21 BBY. Instead of murder, Vos opted only to scare him into backing the Separatist cause, thereby preventing the complications of finding a replacement and avoiding bloodshed. Dooku was pleased by this clever solution.
