Ithorian

Ithorians, commonly referred to as hammerheads or as leathernecks as an insult, were a sentient species from the planet Ithor in the Star Wars franchise. Ithorians had two mouths on the opposite sides of their necks, giving them a deep, rumbling voice. Most Ithorians were peaceful and revered nature. The species' pacifism was so strong that they exiled violent individuals from their homeworld of Ithor. Notable Ithorians include Dok-Ondar, a collector on Batuu, and Momaw Nadon, an Ithorian gardener who was exiled from his homeworld.
