Ithorian

The Ithorians, commonly referred to as hammerheads, were a sentient species from the planet Ithor., though they also had at least one settlement on the planet Takobo, known as Hammertown. They had a unique set of twin mouths on opposite sides of their necks. They were called leathernecks as an insult by Imperial stormtroopers. Their unique throat structure prevented them from speaking Galactic Basic, although an unnamed Ithorian Technician appeared to be able to speak it. There were a number of devices that allowed translation from Ithorese into Basic.

The Ithorians were believed by many to be only peaceful gardeners and philosophers, but those who had encountered the bounty hunters Bulduga and Onca felt differently. For the most part, however, Ithorians were very peaceful and detested violence as well as revering nature. Their own home planet of Ithor was held as sacred ground and hunting there was extremely prohibited. Ithorians could be found spread across the galaxy, even on planets devoid of vegetation such as Coruscant and Tatooine.
