However, their blindness does not appear to hinder their ability to know that they are in the presence of a "blueskin" Andorian or detect obstacles.

, they seldom receive visitors and thus have not been seen by many members of the Federation. Another trait that keeps them from interacting with their fellow Federation members is a strong distaste for space flight: although the Antedeans are a space-going race, space travel is quite traumatic for them. In order for individuals to deal with this problem they induce a catatonic state while in space flight. To awaken from this state takes several hours. Once awakened from the sleep Antedeans are generally ravenous and eat large portions of vermicula.

There is a division in the Antedean race on whether membership in the Federation is a good thing. Ambassador Lwaxana Troi foiled a plot on Stardate

The Ba'ku society consisted of strong bonds between each individual as there were less than a thousand living in a village.

The Borg were discovered to be a group without individuality, where every member is a part of a collective consciousness in an attempt to achieve perfection. They assimilate any species they come into contact with for either biological aspects (for example, Talaxians would be assimilated for their dense physical structure, useful for producing strong, resilient drones) or technological aspects (a species which has developed advanced engines or weaponry would be a sufficiently desirable target for assimilation) all in an attempt to further improve the overall perfection of the Borg as a whole.

The Borg have encountered and assimilated thousands of species, quantity most notable by their designation of Species 8472, although more may have been added to the total since that encounter.

The Borg are not so much a species, as a collection of species. In their assimilated state, most races are altered or augmented with cybernetic enhancements which make them all look similar, or at least instantly identifiable as Borg, making them a pseudo-species.

Encounters with the Borg have varied in type, from the disastrous defense of the Wolf 359 system ("The Best of Both Worlds"), in which many Federation ships were lost, the successful repelling of two Borg cubes from Sector 001 on two separate occasions ("The Best of Both Worlds" "Star Trek: First Contact

s, provoking a strong sexual reaction in many other species.

When she reported to Kirk, Ilia stated that her "Oath of Celibacy" was on record. While the original theatrical release does not expand on this, deleted scenes that were later incorporated into the film include dialogue establishing that she is "as safe as any Human" and that she would never take advantage of a "sexually immature species". Deltan culture is also said to emphasise sexuality heavily: Roddenberry once said that, to a Deltan, sex was like a handshake. Deltans in Starfleet were forbidden from engaging in sexual activity, so as to limit their disruptive influence on other species. Various novels and other non-canon sources contend that sexual activity with a Deltan is such an intense experience that a non-Deltan who engages in such activity with a Deltan risks insanity.

Deltans were not seen or prominently mentioned at all in the 24th-century adventures.

 is a Denobulan. The planet itself is densely populated, having 12 billion people living on one continent.

The Denobulans are humanoid with facial ridges. They sleep less than humans but do hibernate for six days a year. When threatened, Denobulans can inflate their heads like blowfish to scare off predators. Denobulans are also natural climbers, thus making them suitable for exploring caves, canyons and other sheer rock formations. Denobulans, or at least the ones that spend their time away from their planet, have a penchant for scientific research, and each Denobulan that Enterprise has encountered has been a researcher of some sort.

They have long tongues, unprotruded spines, and their toenails grow quickly, which need regular cutting (Phlox mentions that he cuts his once a week). They are long lived, which gives Phlox ample time to gain a number of degrees in various medical fields. They have considerably wide smiles, compared to humans, a fact emphasised by a secondary set of mouth muscles that widen the smile even further. Denobulans have successfully genetically enhanced their race without the violent consequences that humans suffered when they created augmented humans.

Denobulans are polyamorous
Polyamory

, with each Denobulan typically having up to three spouses who, in turn, have up to three spouses. Phlox mentions that his extended family includes 31 individuals. They have complex mating rituals, and they (the males at least) do not like to be touched. Denobulans usually do not have pets, and they abandoned television a long time ago, believing their real life to be much more exciting. Despite their rather liberal views on sex, (male) Denobulans are exceedingly modest when it comes to disrobing in front of others.

Compared to other humanoid species, Denobulans are resistant to Borg nanoprobes and subsequent assimilation. ("Regeneration")

Denobulans used to be xenophobic, but they overcame it and now enjoy contact with other species, presumably after a race known as the B'saari made first contact with them. They were once at war with the Antarans, a neighboring species. They established friendly relations with Earth at least before 2151.

Drayans live on Drayan II, and have little to no contact with outside races. They have a very closed society, due to their species unique attribute of aging. It is uncertain how Drayans are born: They are born looking as if they are elderly, around the human age of 100. From there, they age backwards, growing younger in body as they grow older in wisdom and experience.

When they appear to be the age of a six-year-old human child (making them over 90 in Drayan years), they are shuttled over to one of the moons of Drayan II, where they essentially die. Their bodies disappear, leaving only their clothes behind. This journey is viewed as a sacrament.

Basically humanoid in appearance, Drayans have a colored line down their forehead, the only visible mark that distinguishes them from humans.

The Edo are a species of humanoids on the planet Rubicun III. In general, the Edo resemble physically attractive blond-haired humans. They are a highly and openly affectionate people; according to Tasha Yar

, they make love at a drop of "any hat." In addition, their laws are strange and unusual. The police officers (called "mediators") randomly and secretly select a "punishment zone"; however, the only 'punishment', no matter how trivial or severe the crime, is death by a painless poison injection. The Edo reasoned that since nobody knows which zone has been picked, and nobody wants to risk death, thus nobody would break any laws.

In the TNG episode "Justice", the Enterprise encounters this species. In that episode the planet's overseer entity sends a probe that interfaces with Data, rendering him unconscious for a short time. While accompanying members of the crew on a visit to the planet for shore leave, Wesley Crusher crashes through a protective screen onto new flowers. The Mediators inform him that he violated a punishment zone, and Crusher is sentenced to death. Riker, Yar, and Worf forcibly intervene, forcing Picard to become involved on the boy's behalf (despite the obvious Prime Directive violation caused by doing so).

Elasian

Inhabitants of the inner of the two inhabited planets in the Tellan system. The Elasians are capable of rudimentary interplanetary space flight and have ships capable of reaching the outer planet Troyius, but do not at the time of TOS have warp drive. Bipedal humanoids with coppery complexions and black hair, the men approach nearly two meters in height and have a reputation according to the Federation scientists who performed the initial survey of Elas of being vicious and arrogant; quick to anger and with a highly developed sense of personal honor, fairly bursting with testosterone. Captain Kirk refers to the Elasians as "a warrior race." The women are much shorter, in the vicinity of 1.6 meters, with well proportioned feminine figures and equally vicious natures. Both sexes habitually go armed, preferring their hand weapons in arm sheaths of various types.

The women also can, apparently at will, secrete tears containing a biochemical "love potion." A male of any humanoid race who comes in contact with the tears of an Elasian woman will fall irreversibly in love with her. As shown in Elaan of Troyius the result of such contact is an immediate, deep and lasting devotion between the couple. The secretion of these tears appears to be the method by which Elasian women choose their mates. It may be speculated that this "love potion" is a necessary biological development compelled by the vicious natures of the sexes.

episode "Rivals".

El-Aurians are physically similar to humans, but they can live well over 700 years and have a variety of racial types, with both dark and light skinned members of the race being shown on various Star Trek movies and television episodes. They are considered a race of listeners and often appear very patient and wise.

It is uncertain whether the El-Aurians have any powers beyond those of normal humanoids, but one possible piece of evidence that they do is when Guinan raises a hand threateningly to Q

. This threat seems to be taken seriously at the time, though it is also possible that it may have been largely gestural. Another possible ability of this species is their ability to discern changes in the timeline.

Enaran

The Enarans are the natives of the planet Enara Prime in the Delta Quadrant. They are a warp capable species but have only relatively low level engines. The Enarans are very concerned with personal hygiene and invented radioseptics for hand washing and personal cleaning. In addition to Enara Prime, they maintain an outpost at the Fima Colony.

Physically, the Enarans are humanoid with red spotting near the eyes and forehead. As a species they are telepathic, able to implant memories in another person whether they are willing or not. However, making telepathic contact with an unwilling person is deeply condemned.

Physically the species is humanoid with dull brown skin, and few distinguishing features - hairless, and with few noticeable facial features, it is almost impossible for other species to distinguish between individuals of this race.

They use surveillance on passing ships for future raids. This is done by special surveillance ships, hiding in Nebulae for example, who use sensors to assess the tactical risk of attacking passing vessels and the available loot. They use cloaked ships to sneak up on vessels.

The Hirogen view all other races as prey, and make sport of pursuing what they deem worthy adversaries. With this in mind, some far-seeing Hirogen believe their society, which has broken up into a number of factions each engaged on their own hunts, has become too divided to survive in the hostile Delta Quadrant.

Hirogen are typically much taller than a human, perhaps seven to eight feet in size. They are powerfully muscular. It can be surmised that their close combat capabilities outstrip those of a typical Starfleet officer by quite a margin. Hirogen hunters of all ranks wear tough blue armour, generally with face masks. Before a hunt, all Hirogen hunters colour their faces with some type of war paint.

Human (Augment)

Augment is a term used to describe a group of genetically engineered Humans created by DNA resequencing in the late 20th century, a group of Klingons, and other genetically-engineered beings.

Kobali

The Kobali are a tall, bald, ash-purple species found in the Delta Quadrant. They procreate by taking the corpses of other races, reanimating them (which usually results in severe memory loss of their previous life), and altering their cellular structure so as to make them entirely Kobali. Such changes are very difficult, if not impossible, to reverse - even on a cosmetic scale. They appear to be a (at least medically) technologically advanced warp-capable species. Very little is known about their physiology, other than that they have a mutispheric brain and are considered quite intelligent (compared to humans). Their language is very complex and robust, their central motto is "Do not harbor ill-will towards those who brought you death, for they gave you the chance to live again."

. However, the contact did not go well: While being led on a tour of the ship, the Kreetassan delegation abruptly turned tail and left in a huff. The Enterprise crew quickly learned the reason: In Kreetassan culture, the simple act of eating a meal is viewed as an intimately private ritual, similar to mating. When the Kreetassans saw the Enterprise's mess hall, they were so mortified by the sight of many humans eating meals together, that the first contact between the two species was abruptly cut short. (Episode "Vox Sola")

Later, the Enterprise visited the Kreetassan homeworld - inadvertently causing another incident when Captain Archer's dog, Porthos, relieved himself on a sacred Kreetassan tree. Captain Archer, to save face, was forced to perform an elaborate ritual of apology (mainly involving cutting pieces off the tree and arranging them in an intricate pattern) to the Kreetassan government. The Enterprise needed a machine part for their warp engines, but the Kreetassan government was so impressed with Archer's apology ceremony because he did it with such style, they gave the Enterprise two replacement parts.

The Krenim Imperium is a technologically advanced race in the Delta Quadrant. Their military revolves around temporal based weapons that distort the space-time continuum. Armed with Chroniton Torpedoes, Krenim Warships are able to take on even the most well armed vessels. Being out of sync with normal space-time, the torpedoes can penetrate any conventional shielding. One example of the advancement of the Krenim is the Temporal Weapon Ship that was commanded by Annorax.

In this story arc, the Lanatosian homeworld was about to be destroyed by a comet and the Lanatosians, as members of the Federation, asked the Enterprise to help them evacuate - which seemed unusual as the Lanatosians have space-travel capability themselves; it transpired they needed the help to remove some sacred monuments rather than people. During the mission, Troi and Data discovered that the Lanatosians had concealed the fact that there was another intelligent species on their world - the telepathic, sea serpent

-like Skriiti. Disregarding them as mindless animals, the Lanatosians hid them from the Enterprise crew to avoid them taking up space on the ship and leaving less room for the monuments. Much to the Lanatosians' disgust, Captain Picard insisted that the Skriiti should be evacuated and the monuments left behind.

Once taken to their new home, the Lanatosians were advised to put aside their differences with the Skriiti and work with them to rebuild their society. Whether they did this was not shown, but in the final panel featuring the two races, a Lanatosian appears to be peacefully talking with a Skriiti.

Malon

The Malon are a technologically advanced humanoid species in the Delta Quadrant.

Their homeworld is Malon Prime. It is supposedly a very beautiful planet, but kept that way only because the Malon dump all their industrial "contaminated antimatter" into space. This dumping comes at a high cost: the regions of space contaminated by Malon waste become uninhabitable. While it is thus official Malon policy to dump waste only in uninhabited space, some "waste export" captains have been known to cut corners by deliberately dumping close to inhabited space. The Malon also regard adverse, unintended consequences of their dumping, such as accidental discharges of radioactive material, as simply the cost of doing business.

In addition, the salary for waste export vessel crew members, especially "core laborers" who work directly with the waste storage tanks, is extremely high to match the attrition rate due to death by radiation exposure. Crew members who sign on for just one export mission, even if they do not die, may still suffer severe, progressive, and incurable sickness from the "theta radiation". (Under Malon law, if any crewmember dies from sickness incurred in the line of duty, his or her family is compensated for the loss.) The Malon tell legends of "Vihaar," monstrous life-forms created by the radiation that haunt, and attack, Malon ships. In reality, Vihaar are export vessel crew members so sickened and deformed by the radiation that they have been driven insane ("Juggernaut").

had several encounters with the Malon, and at one time even offered to give them Federation treatment technology to make the waste harmless, or even beneficial.

It is unknown whether the Malon ultimately adopted clean technology

. There has been no formal contact with the Malon government as such, merely a series of accidental encounters with their ships. Since these encounters have occurred over thirty thousand light years apart, it is possible that Malon territory extends across these kinds of distances - making their space far larger than the Federation. However, the Malon are known to have access to at least one stable "spatial vortex" - apparently a form of wormhole. It is possible that they have access to others which allow them to cross large distances, or even that they are able to build such phenomena themselves.

Mari

The Mari are a telepathic species indicative to the Delta Quadrant. When last seen, they had a near-utopian society.

episode "Is There in Truth No Beauty?".

The Medusans are some of the few (if not the only) incorporeal beings that are active members of the Federation. Because of their different structure and correspondingly different sensory systems, they are much better suited for space travel than most members of the Federation. However, it is very difficult for the Medusans to interact in a meaningful way with the mostly-humanoid Federation. This is because the Medusans have not completely shed their physical form and must always have it with them. This physical form is said to be so hideous that a humanoid viewing it without protection will be driven hopelessly insane. An interesting side note is that while the Medusans' body is grotesque in the extreme, their advanced minds - when viewed by those with telepathic abilities - appears to be quite beautiful.

The name came from the ancient Greek mythology where Medusa

, the planet's atmosphere was "completely devoid of nucleogenics". The intergalactic explorers, upon realizing their mistake, took upon themselves the responsibility of taking care of the Ocampa. The Caretakers built a massive underground cavern with access to the only remaining natural water source on the planet, and supplied it with energy via transmissions from a gigantic orbiting station. From this station, the "Caretaker" dutifully watched over the Ocampa, supplying every need and protecting them from every danger. As a result of this life of absolute ease, the Ocampa eventually stopped using their mental powers and, due largely to their short lifespans, eventually forgot about them completely. Over time, the Ocampa became completely dependent upon the Caretakers for all necessities of life.

The Ocampa remained in this state until the only Caretaker remaining on the station began to die. This Caretaker reasoned that only his own offspring would be able to carry on his work of protecting the Ocampa, and so began a galaxy-wide search to find a genetically compatible race through which it might produce offspring. This search consisted of a long series of trans-galactic ship-jackings, which is how the Federation

Pakleds tend to over-emphasize their simple-mindedness to their benefit: their simple and childlike speech ("We look for things. Things that make us go. Can you make us go?" "We are smart, we are strong!!") leads their victims into thinking the Pakleds are harmless and helpless; the Pakleds request help from the target ship, wait until their benefactors' guard is down, then use a show of force to take what they need.

The Pakleds were first seen in the TNG episode "Samaritan Snare". In the episode "Brothers", Lore comments that after being reassembled he drifted in space until picked up by Pakleds. Several Pakleds appeared as background characters on Star Trek: Deep Space Nine

, the Preservers are an ancient race of aliens who visited Earth thousands of years ago and removed some human specimens from the planet. The aliens then "seeded" these humans on other planets within the galaxy that had similar Earth-like environments.

No one is sure why the aliens did this, and most speculate that it was part of a great experiment to test the adaptability of humans, whom the aliens believed would one day serve as their replacements. It appears that the Preservers themselves were a dying race and no longer exist. The only evidence of their culture are ancient artifacts and ruins that litter various humanoid worlds. Many races that have been encountered have a sketchy pre-history, some unable to explain their sudden appearance on their worlds, while other cultures have clearly documented evidence that they are not native to their home planets.

The Preservers are discussed explicitly in the Star Trek: The Original Series

The Sheliak apparently regard humans as a lower species, and refuse to have any contact with the Federation beyond what is necessary to enforce the Treaty of Armens. They have a stubborn insistence on protocol which Jean-Luc Picard has used against them. Sheliak colonists being transported to a new planet are referred to as a "membership".

The Sheliak inhabit types of planets that humans normally do not, e.g. H-Class worlds with levels of radiation that would be fatal to most humanoids. Sheliak appear vaguely humanoid, but with a dark, very rough skin and few identifiable features.

The Expanse is extremely hostile to residents of our dimension, and those that enter have great difficulty in leaving. The Expanse is also not yet entirely suitable for the Sphere Builders.

The Sphere Builders act as antagonists in season 3 of Star Trek: Enterprise, where they manipulate the Xindi in order to advance their goals of conquest. They are eventually defeated by the Enterprise crew.

Silver Blood

Y-class planets, also known as Demon-class planets, are the most inhospitable to known humanoid races. On one such planet located in the Delta Quadrant, even though the surface temperature was ridiculously hot, an away team of Tom Paris and Harry Kim found a small pool of cool, viscous silver liquid. It was found that it created a perfect copy of any organic matter it came in contact with. Perfect, except for the fact that it still needed to breathe the indigienous gases of the planet. Before it had copied Tom and Harry, it had never known sentience, and now it wanted it badly. So badly that it was willing to destroy the USS Voyager and all the "originals" in order to copy them. Janeway convinced them to let her crew continue on its way if she let them copy the Voyager crew.

In a later episode, we see that the Silver Blood-copies forgot that they were just copies, created an entirely new Voyager out of silver blood, and were trying to make their way back to Earth just like their original counterparts. However, they made some adjustments to their warp core, causing their Silver Blood bodies to deteriorate, as did the ship. They tried to find a new Deamon-class planet to set down on, but the miners on it would not let them near it, and they were not in any shape to put up a fight about it. The last surviving crew member, Harry Kim (who was the first one to get copied, oddly enough), and the rest of the ship completely deteriorated mere moments before they were to meet up with the real Voyager.

Tak Tak

The Tak Taks live in the Delta Quadrant and have a method of communicating not only involving spoken words but also ritual gestures. They are very set in their ways, and if someone makes rude gestures (such as putting their hand on the hips) they become very violent.

Takaran

The Takarans are a humanoid species native to the planet Takara.

Takarans are characterized by a very unusual anatomy and physiology where their internal organs are not as distinct as those of most humanoids – their organ systems are much more evenly distributed around their bodies, resulting in Takarans having a very high resistance to injury. Takarans also have voluntary control over their own physiology down to a cellular level and can place themselves in a form of stasis resembling death.

To Starfleet medical equipment, only the rate of cellular decay could verify whether a Takaran was dead or alive – a slow rate of cellular decay was indicative of a Takaran in voluntary stasis; the rate of cellular decay would be much faster if the Takaran were truly dead – this was unknown to Doctor Beverly Crusher until 2369.

Takarans are also able to put only a part of their body in stasis at a time, enabling them to slow injury in specific areas and thereby reduce the overall effects of the injury. (TNG: "Suspicions", episode 248)

NOTE:Since Dr. Crusher knew little of Takaran physiology and also stated Jo'Bril was the first Takaran she'd ever met, it is unlikely that Takarans were Federation members as of 2369.

Vaadwaur

Vaadwaur appear in the Voyager Season 6 episode entitled Dragon's Teeth (Star Trek: Voyager). The Voyager crew takes refuge on a planet that appears to be experiencing a nuclear winter. The crew discovers that there are stasis pods and revives the inhabitants who claim that they are the Vaadwaur.

The Vaadwaur are reptilian in appearance and appear on the surface to be physically similar to the Cardassians; they have a pale, grey skin and pronounced neck ridges. They are an expansionist military culture that controlled areas of the Delta Quadrant. They are said to have used subspace corridors to travel great distances and surprise other species with sneak attacks. They also seem to be a duplicitous race in that they will agree to certain conditions with another species and then go back on their word. No wonder then, that the word "Vaadwaur" in ancient Talaxian means "fool" - in the sense that it is foolish to trust such an enemy, despite common goals.

After an armed conflict, 53 ships of the Vaadwaur managed to have escaped the planet they were on and entered a subspace corridor. Even though Seven points out to Captain Janeway that their technology is effectively 900 years behind the times, Janeway sees this race as being extremely adaptable and aggressive; traits that could help them establish their hold on regions of the Delta quadrant.
