Ithorians, commonly referred to as “hammerheads,” were a sentient species from the planet Ithor. Living in the forests or jungles, Ithorians had a unique set of twin mouths on opposite sides of their necks with four throats, making them speak in stereo with deep, rumbling voices. They had two stomachs. Their unique throat structure prevented them from speaking Galactic Basic Standard, although this was mitigated by a number of devices, such as the translator collar, which allowed translation from Ithorese into Basic. They could be force-sensitive.

Ithorians were called “leathernecks” as an insult by Imperial stormtroopers. The Ottegan species were a genetic offshoot of the Ithorians, and had a similar physiology, possessing only one mouth instead of two.

Most Ithorians were peaceful and revered nature. The species’ pacifism was so strong that they exiled violent individuals from their homeworld of Ithor. They considered Ithor sacred and strictly prohibited hunting on the planets surface. Though Ithorians tended to their forest gardens on Ithor, a majority of the planet’s surface was covered with the Mother Jungle, a vast rainforest that the Ithorians considered sacred, forbading anyone from setting foot within.

The Ithorians were organized into herds, extended tribes connected by tradition and intermarriage.

Ithorian culture valued nature, handcrafting several spiritual objects. Ithorian totems were hand-carved from stone and marked an Ithorian’s grave, giving it a deep spiritual meaning on Ithor. Ithorian Weather Chimes were handcrafted and prayed to for fertile soil and good weather for gardening.
