Xindi - Arboreal Xindi - Arboreals were members of the multi - species Xindi race . They were one of the most peaceful of the six species , which shared a common gene tic ancestry . Physiology . In appearance , Arboreals were covered with hair ( at least their hands and head s were ) and had long , sharp fingernails , dark eye s , and a ridge running from their nose s to the back of their heads . ( , " et al . " ) Arboreals were susceptible to a certain type of mutagenic virus created by the Loque ' eque . ( ) Arboreals had a dislike and perhaps even a fear of water . ( ) However , they did drink beverages . Arboreals were considered to be lethargic by the other Xindi species . They were also extremely calm , even when taken hostage . ( ) Technology . Arboreals were intelligent enough that some worked on manufacturing kemocite , in a facility specifically for doing so , which was on an Arboreal colony . The Arboreals who labored there provided many species with kemocite . ( ) The Arboreals utilized a diversity of spacecraft , such as a type of Xindi - Arboreal starship and a form of landing craft . ( ) Arboreal ships also included a vessel that was small , incapable of outmatching an Osaarian merchant ship , and contained a component that had Xindi writing on it . This Xindi craft also carried fuel , supplies , and the Xindi database . ( ) Hand - held technology used by the Arboreals included a type of scanner . ( ) History and culture . As the third species of Xindi discovered by the crew of , it was believed by Doctor Phlox that this species probably evolved from some sort of arboreal sloth . ( ) As with the other Xindi species , the Arboreals originated on the planet Xindus , before that planet ' s destruction . ( ) Two Arboreals , including Jannar , sat on the Xindi Council . ( ) In 2153 , many more Arboreals lived on Azati Prime , whose population of Arboreals and Primates numbered over 1000 . ( ) The small , aforementioned Arboreal craft was on an interstellar voyage for at least a few months . At one point in the journey , the Arboreal crew visited the Loque ' eque homeworld , where an Arboreal landing craft departed from the ship and traveled to the planet ' s surface , where it remained . ( ) The Loque ' eque homeworld was the larger ship ' s last destination before , in the same week or thereabouts , it was attacked and overpowered by an Osaarian merchant ship which stole fuel , supplies , and the Xindi database from the Arboreal vessel . ( ) The Arboreals resisted the Osaarian pirate s , so the Osaarians destroyed their ship . ( ) There were fewer than a hundred Arboreal colonists who resided on the planet where the kemocite refinery was located , approximately eighty of whom worked inside the facility itself . During the construction of the Xindi weapon , the Arboreals were requested by Xindi - Primate Degra to produce shipments of highly refined samples of the substance . The laborers regarded this as a cause for celebration , realizing the wealth this operation would bring to their colony . Although Degra claimed the kemocite would be used for research , the workers never considered why such pure kemocite was requested , and the facility ' s primary technician , Gralik Durr , later admitted that the greed of the Arboreal colonists may have blinded them from realizing the kemocite was to be used in the construction of a weapon to destroy Earth . After about six months in which they produced the shipments of purified kemocite , the workers were being pressured by the other Xindi species into continuing to use the facility to manufacture huge amounts of kemocite . Although there were impurities in three of the kemocite production cycles , the Arboreals found a ruptured seal which was thereafter repaired before another production cycle began . Their efforts to make up for the error included assigning two additional teams of workers to assist in synthesizing kemocite . The Arboreals expected that Degra and a Xindi - Reptilian crew wouldn ' t arrive for the last shipment until three days after the Reptilians and Degra actually returned to the colony . The Arboreal colonists were surprised by the advanced schedule and delayed their turnover of the final shipment , causing the Reptilians considerable annoyance . The Arboreals were regarded as a somewhat positive example by Degra , however , who observed the Reptilians could learn qualities such as patience from them . The Arboreal workers meanwhile were unknowingly ( with the exception of Gralik Durr ) visited by an away team from " Enterprise " and even faced obliteration by the Starfleet officer s , though Captain Jonathan Archer ultimately decided not to annihilate them . Also unbeknown to most of the laborers was that Gralik Durr secretly sabotaged the final dispatch of kemocite which was shipped by the Xindi visitors . ( ) Once Degra discovered the Sphere - Builder s had lied to the Xindi and manipulated them into building the Xindi weapon , the Arboreals were the only species he initially reckoned had any probability of realizing the treachery of the Sphere - Builders , when provided evidence of this from " Enterprise " . Arboreals contributed to a protective fleet ( also including Xindi - Primates and - Aquatics ) which escorted " Enterprise " to the Xindi Council planet . Shortly thereafter , the Arboreals eagerly listened to and considered the facts about the Sphere - Builders , as proposed to the Council ( including the pair of Arboreal representatives ) by Captain Archer . As Degra had suspected , the Arboreals were indeed fairly easily persuaded to accept the truth about the deceitful Sphere - Builders . Arboreals even helped form an armada that fought against the Xindi - Reptilians and - Insectoids , after those two species launched the Xindi weapon in opposition to the Council having officially agreed to postpone the weapon ' s launch . ( ) Although the fleet was left behind in favor of tracking the weapon with the relative quickness of Degra ' s ship , three Arboreals were aboard that vessel when it approached Earth and when the speedy craft took part in ultimately successful efforts to destroy a Xindi - Reptilian starship guarding the weapon and to prevent the weapon from annihilating Earth . ( ) Uniforms . Arboreals wore belts that seemed to indicate their position . For example , the Arboreal representatives to the Xindi Council wore five belts whereas the Arboreals who were assigned to the kemocite refinery wore three belts . An Arboreal who became infected with the Loque ' eque mutagenic virus and was then incinerated to death by Commander Tret ' s people also wore three belts . ( ) Each of the two Arboreals who sat on the Xindi Council wore a soft - looking full - length coat which was primarily gold - colored . White furry material was at the shoulders , which were ruffled , as well as at the sleeves and at the borders of the coat ' s insides in the middle of the front , where the sides of the coat crossed over a black undershirt . The shirt was occasionally visible at the neck . The coats also had detailed gold and black ribbon trim . The belts on these coats were wide and in varying metallic hues , as Jannar ' s belt was mainly colored gold and his aide ' s was silver - colored . Also , each of the belt ' s five buckles matched the color of the surrounding belt fabric . Another difference between the outfits was that Jannar ' s coat alone incorporated a decorative , seemingly gold broach attached to the front , with a chain that stretched over the right shoulder and was affixed to a second metallic clasp on the back . ( , " et al . " ) Each of the Arboreal refinery workers who were assigned to the kemocite mining facility typically wore a less decorative uniform . These were long - sleeved , predominantly pale green jumpsuits , with beige trim accents . A wide , brown belt with three strips was wrapped all the way round the waist , fastened in three places with a vertical series of three metallic buckles . Each of the suits ' shoulders was emblazoned with a red and white mining colony uniform patch showing Xindi iconography . Each shoulder patch consisted of a red - colored triangle with rounded sides , containing a white background on which was a red , three - pointed icon centered with rounded blade shapes wheeling out from its points and a white Xindi icon in the middle . ( ) Appendices . Background information . In the final draft scripts of third season episodes and , the Xindi - Arboreals were commonly referred to as " Xindi - Sloths " . This was also how the species was referred to in the final draft script of ( though the infected Arboreal who transformed into a Loque ' eque was much more commonly referred to simply as a " Humanoid " ) . The way the species was referred to was changed by the end of the third season , as scripts for installments such as and instead referred to them as " Xindi - Arboreals " . The first time the species was specifically named " Arboreal " in canon was in . When designing the Xindi - Arboreals , there was only enough time to draw a tiny pen sketch of the facial design ; most of the work that went into conceiving it was done by sculpting clay , which was begun after the makeup artists realized which direction they wanted to take the design in . Although Makeup Supervisor Michael Westmore found that the Xindi - Arboreal makeup was one of the easiest to put together in general , the design ended up involving prosthetic masks whose frontal hair was a large challenge and presented him with much work . Each mask included not only facial hair but also some head - hair . Westmore implied that the Arboreals were probably vegetarians by giving them large teeth , which were almost like horse teeth and were twice the size of Human teeth . Contact lenses were not deemed necessary , as at least most of the actors who were cast to play the Arboreals had very dark eyes . For each of the Arboreal - playing performers , nails – similar to those of a sloth – and hair were crafted into a pair of gloves . " " So they can literally put their arms on and go to work , " " Michael Westmore said of the actors . " " This is the first time we ' ve done that with [ an alien ] [ . . . ] this complex . " " The Arboreals were made to feature a variety of shades . " " They range from light beige to darker brown undertones on the skin , " " noted Michael Westmore , " " and then the hair that grows over them is different – from gray to blond , red to gray , like there ' s an underbase and an overbase to the hair . " " For the Arboreals ' head - hair , Hair Designer Michael Moore obtained fur fabric samples from National Fiber Technology . " " I started looking at ' em and began to think , ' Hmm , this ' d work . ' It was more like a hood than a wig ; I basically put it on a head form upside down to put it together , and then when I reversed it the hair was all on the outside . " " During production on " Enterprise " s third season , the makeup and hair departments blended their two respective types of head - hair . Any potential of a hard line between these was avoided by covering a strip of hair – which looked virtually Human and was at the front edge of the wig – with the hair Michael Westmore had crafted into the back of the mask ' s top . Moore ' s main concern with the wig was maintaining the stripe down the middle of the head . The duration it took to apply the Xindi - Arboreal make - up is uncertain . Jannar actor Rick Worthy once suggested that the time it took to apply this make - up was about as long as it took to apply a typical layout of Klingon facial prosthetics . Focusing on the Arboreal make - up , Worthy said , " " The makeup process was long , maybe 2 - 3 hours usually early in the morning . " " In another interview , he repeated this estimate exactly and added , " " It took half that time to take it off in the evening . " " However , in yet another interview , Worthy reduced the duration significantly , saying , " " For " Enterprise " , they had me in the makeup chair for probably 1 . 5 hours or less . " " Some Xindi - Arboreals in " The Shipment " were evidently portrayed using CGI . Eden FX accomplished the task of digitally representing those Arboreals . ( ) Executive Producer Rick Berman once commented that , of all the Xindi species , he thought " the Xindi - Sloth " looks especially good . ( ) With similar gusto , Archer actor Scott Bakula praised the Xindi - Arboreals as " quite wonderful . " ( ) Rick Worthy has repeatedly likened the look of Jannar to the design of the " Star Wars " character Chewbacca . Several Arboreal scientists ' costumes from " The Shipment " were sold off on the " It ' s A Wrap ! " sale and auction , including those worn by Sam Witwer , Louis Ortiz , Clynell Jackson , and Jack Alsted . Each of the suits incorporated their own costume tag . Confirmed sales were between US $ 260 and US $ 324 , although the costumes worn by Witwer and Alsted both required a second effort to sell them before they were bought . A uniform patch from one of the Arboreal scientist costumes was also sold off on " It ' s A Wrap ! " , as was Rick Worthy ' s costume as Jannar , the latter of which fetched US $ 360 . 88 . " It ' s A Wrap ! " Project Manager Colin Warde once described Jannar ' s costume as " one of the most elaborate costumes " included in the entire auction . ( ) Furthermore , two Arboreal outfits were combined in a group of four Xindi costumes which were sold as part of the " " auction . The Arboreal costumes were Gralik ' s jumpsuit worn by John Cothran , Jr . in " The Shipment " and , as worn by Aldric Horton , a leather coat ( presumably for Jannar ' s aide ) which had white imitation fur lining and silver trim . Apocrypha . The novelization of the episode " The Xindi " refers to the Xindi - Arboreals as " Xindi - Marsupials . " It describes them as being very slow - moving and says the Xindi - Humanoids regarded them as having thoughts mainly about napping upside down in trees . An account in the book says , " " It was easy to believe , given the marsupials ' tendency toward torpor , that they were harmless and stupid , but such was not the case [ . . . ] While they much preferred the company of family , [ they ] were shrewd when it came to politics , and had proven themselves fierce fighters when attacked . " " The novelization goes on to explain how , using their thick claws , the Arboreals were capable of violently tearing a Xindi - Humanoid ' s body with a single , strong swipe , even though Arboreals were inherently affable .
