Ithorian / Legends Ithorians were a mammalian herbivorous sentient species from the planet Ithor . They were commonly called " Hammerheads " by less sensitive beings because of their long , curving neck and T - shaped head . They found this nickname offensive . Biology and appearance . Ithorians had two mouths and four throats , allowing them to speak in stereo . Female Ithorians had two humps on the back of their head , while males had only one . They had glossy , usually brown flesh . They stood roughly between 1 . 8 to 2 . 3 meters from eyestalk to toe . Their reflexes and coordination were somewhat slower than that of average humanoids . In addition to allowing them to speak their unique stereophonic language , the Ithorians ' four throats also had the ability to violently expel air , resulting in a deafening and potentially concussive scream . Although even common Ithorians possessed this strange talent , those with Force training ( such as Jedi Master Roron Corobb ) could push enough power into their sonic bellow to shatter iron and shred plasteel . Despite this fact , most Ithorians went their entire lives without ever resorting to violence , and so the ability remained relatively ambiguous . Ithorian youths were known as " pupa , " and were commonly glassy - eyed , appendageless and limber , until they metamorphosized . After the molt , Ithorians lost an aural flap and every locomotion tube , gained lumps , craters in their craniums and an appetite for ant - flies . An adult Ithorian could father several thousand offspring . History . Ithorians were natives of the planet Ithor , a lush world with sprawling rain forests . The Ithorians worshipped Mother Jungle , and long ago vowed never to desecrate their planet . Once they discovered repulsorlift technology , the Ithorians built expansive " herdships " floating in the skies above their homeworld . The species migrated to these platforms , ensuring that Ithor would remain pristine forever . These herdships eventually were given the ability to travel interstellar distances . The Ithorian people were led by their high priest . First contact with the Republic occurred in 12 , 000 BBY . Abroad , Ithorians integrated well with the Galactic community . Their own language was incredibly beautiful , yet difficult to learn , as the Ithorians had twin mouths on opposite sides of their necks . Fortunately , they could speak Basic , albeit with a strange accent . Each Ithorian herd was presided over by a Force - sensitive individual who served as both a priest and healer . The Ithorians were crucial to the efforts to restore many planets that had been devastated by the Mandalorian and Jedi Civil War s . One notable example was Telos IV , whose reconstruction was minutely directed and supervised by Chodo Habat and his herd . Around the time of the Cold War , a proxy conflict between the Sith Empire and Galactic Republic , it was discovered that the previously unknown species responsible for building the technological wonder that were the Heffrin Aqueducts on the planet Heffrin , were in fact early Ithorian explorers . This led to great debate among the Ithorian culture . Ithorian society maintained its peaceful nature by exiling those who had a tendency towards violence and aggression . Two such exiles were the Moomo brothers , Dob and Del , who worked for the Galactic Republic as hired muscle , although they were less than competent in their efforts . An exile named Momaw Nadon was present in the Mos Eisley cantina shortly before the Battle of Yavin . During the Yuuzhan Vong War , Ithor was destroyed by the Yuuzhan Vong as part of their invasion plan . They chose to destroy this planet , even though it was a lush jungle world , because one of the trees ' pollen could cause their Vonduun Crab Armor to expand rapidly , killing the Warrior . Many years after the Yuuzhan Vong invasion , Leia Organa Solo convinced Chief of State Cal Omas to allow the Ithorians to resettle on the planet Borao in the Inner Rim over RePlanetHab , a large reconstruction conglomerate . Other Ithorians settled on Öetrago , Upell and Felucia . Society and culture . Ithorians worshipped the " Mother Jungle , " a spiritual entity embodying the lush , tropical ecology of their world , Ithor . They were generally devoted environmentalists , staunch herbivores , and complete pacifists , devoting much time to contemplating their ecology , studying plants and their uses and the overall respecting of all living things . Most Ithorians never set foot on their own planet , instead living in floating cities above their world called herdships . Only three of their continents had been explored and harvested , the other two never having been touched by Ithorian hands . This demonstrated their extreme belief in the protection and sustaining of their environment which was apparent through their " Law of Life . " The Ithorians practiced a communal form of government . Each herdship was autonomous and self - supporting . However once every Ithorian season ( about five standard years ) , the herds gathered for " the Meet , " a grand gathering above the surface of their world , where the herd ships would join each other in a festival and regal ceremony . Within Ithorian society , there were a priestly group known as nature priest s who communed with the " Mother Jungle " and had a deeper connection to the Ithorian homeworld . Within the trading guilds themselves , Merchantate s were present who dealt with business matters . The Ithorian ’ s curious and gregarious nature meant that many found their way off - planet via their floating herdship ’ s space - worthy counterparts . Many became galactic traders , traveling the stars either independently or as part of their herdship . They would only resort to violence if threatened , and they were more likely to use their sonic bellow than a weapon . Because of their mild demeanor , most Ithorians avoided war in general , although the Rebel Alliance did boast a few among its ranks . Their pacifistic nature meant that they refused to touch things that came as a result of bloodshed . When dealing with others , Ithorians were always supremely polite . They were very conversational and had profound respect for the views of others . Though often described as likable and friendly , many sentients found them altogether dull . Even when they had disagreements , Ithorians were unlikely to discuss their grievances with anyone unless the offending party was present . To do otherwise was considered rude . Ithorians were commonly named after creatures on their planet , such as the Flen and Gillom . Many females were named after the Cellwan , Haali , Ivuur , Oovei , Vonnuvi , and Wimmel ; many males were named after the Boolon , Murr , Neelig , and Waawat . Aamaw , meaning " firelight " , was also a very common name . Ithorians in the galaxy . Practicing their gentle nature even when offworld , many Ithorians served as explorers , diplomats , peace officers and navigators . Despite their reputation , not all Ithorians were so peaceful . Rarely , violent and unruly Ithorians were born and subsequently banished from their homeworld or herdship . Such Ithorians often became drifters and bounty hunters , like Del and Dob Moomo . On some poor worlds where Ithorians had established trading centers , Ithorians were happy to give produce away to impoverished locals . Ithorians also pioneered several crop education programs for produce growers on poor and uneducated planets . Many Ithorians were Force - sensitive and went on to serve the Jedi Order , as the Jedi Code valued the good nature that Ithorians so cherished . Behind the scenes . The Ithorian puppet suit used in the Mos Eisley cantina scene of " " was designed by Ron Cobb . This puppet was used for Momaw Nadon and Deneb Both . Interestingly , it featured four fingers on each hand , while later Ithorian designs , such as Roron Corobb and Tendau Bendon ( both of whom appear chronologically before Nadon and Both ) feature five - fingered hands . Most sources other than Cobb ' s puppet , including " The New Essential Guide to Alien Species " , seem to favor the five - fingered design . In the " Star Wars " radio drama , Luke commented on seeing a Meerian Hammerhead while in the cantina . Since then , another species has been identified as Meerian s .
