Species List

Name : A B C D E F G H I J K L M N O P Q R S T U V W X Y Z # All

NameUp Description First seen
Acamarian1 Species native to the planet Acamar III. The Acamarian culture is divided into a clan structure; any act of violence towards one member of a clan was considered to be an act against all members of that clan. This led to a great deal of inter-clan warfare which eventually threatened the whole Acamarian society. They were successful in forging peace, but the Gatherer group split off from mainstream culture rather than participate in peace. This changed in 2366 when Captain Picard and Sovereign Marouk managed to convince the Gatherers to return to Acamar.1 The Vengeance Factor
Akaali2 A primitive humanoid species discovered by Enterprise, the Malurians ran a covert mining facility on the Akaali planet which poisoned the locals.2 Civilization
Akritiri3 A technically advanced species, the Akritiri were a repressive species who operated an unjust legal system and confined their prisoners in a space station under inhumane conditions.3 The Chute
Aksani4 Delta quadrant species which took part in a regular sub-warp shuttle race4 Drive
Al-Leyan5 Probable species name, though this is not certain. Professor Galen planned to travel from Deep Space 4 to Caere IV on board an Al-Leyan transport.5 The Chase
Alcyone6 People who destroyed the second to last Tarellian plague vessel6 Haven
Aldean7 Species which had been long considered to by mythical as of 2364. In that year the Enterprise-D discovered the planet Aldea, which had been hidden behind a cloaking device for millennia. The Aldeans were highly technology advanced, but had become culturally stunted by their reliance on technology that they no longer understood or were capable of maintaining or repairing. They were suffering from a specieswide inability to have children which, unknown to them, was a result of their own cloaking device. The device had destroyed their ozone layer, resulting in increased radiation reaching the planet. The Enterprise was able to reseed the ozone layer and repair the damage.7 When the Bough Breaks
Aldebaran Serpent8 Reptilian life form with three heads. Q once appeared to the Enterprise crew as an Aldebaran serpent.8 Hide and Q
Aldebaran Shellmouth9 Creature famous for being tight-lipped. McCoy once compared Spock to an Aldebaran Shellmouth.9 Amok Time
Aldeberan mud leech10 Species whose secretions acted as a natural sedative. Putting one on your chest and another on your abdomen an hour before going to bed was a cure for insomnia.10 Anomaly
Algolian11 Humanoid species with golden skin and various ridges on the head. Algolians known for the ceremonial rythms they plan on important occasions.12 An Algolian was present on board the Federation Archaeological Council's annual symposium at Tagus III.13 Some Algolians were to be seen on Deep Space Nine from time to time.14 Various Next Generation episodes
Algorian Mammoth15 Large creature. Doctor Bashir considered 30 cc's of triptacederine to be enough to anesthetize an Algorian mammoth, though Garak noted that he had taken that much and could barely feel it.15 The Wire
Alien Goat16 These goat-like creatures were kept on the planet where Zobral's people lived.16 Desert Crossing
Alien Spider These creatures were native to a planet which Lieutenant Paris and Commnader Tuvok crashlanded on in 2375. They were edible, though somewhat difficult to catch.17 Speculative
Allasomorph18 This non-corporeal species are capable of assuming any shape at will.18 The Dauphin
Alpha 117 Dog19 Canine-like creature from the planet Alpha 117. In 2266 one of the creatures was "split" by the Enterprise transporters, malfunctioning as a result of an element from the planet. The attempt to recombine the two creatures succeeded, but the animal died in the process.19 The Enemy Within
Alsuran20 A Delta Quadrant species which was erased form time by Annorax. Annorax kept some of their foods aboard his Timeship.20 Year of Hell, Part 1
Altarian marsupial21 Animal Dr. Phlox used in medicine. Their droppings contained the greatest concentration of regenerative enzymes found anywhere.21 Broken Bow
Altec A Humanoid species which resided on the planet Altec in 2365. Along with the inhabitants of Straleb, the Altecs were members of the Coalition of Medina. The species was relatively primitive as compared to the Federation.22 Speculative
Altoran23 A pair of twinned Miradorn claimed to have purchased an artifact from an Altoran trader.23 Vortex

Alverian Dung Beetle27 Insect known for being unpleasant. In preparing Odo to masquerade as a Klingon, Worf compared him to an Alverian Dung Beetle.27 Apocalypse Rising
Amoeba28 Single celled life form up to many thousands of miles long28 The Immunity Syndrome
Anaconda29 Earth snake. Hoshi once saw Anacondas on a nature trip.29 Fight or Flight
Anaphasic life form30 Energy creature which lived within a candle flame30 Sub Rosa
Andarian31 Andarian glass beads were mentioned in this episode, and are presumably manufactured by Andarians.31 Business as Usual
Andorian Amoeba32 Single celled life form native to Andoria32 Tuvix
Andorians33 Founder members of the Federation34, the Andorians are a violent warrior race.33 Unlike the Klingons they tend to fight for purely practical gain rather than for personal honour or glory. Andorian culture stresses discipline and self control, and this can make them appear unsympathetic at times.

Physically, Andorians are humanoids similar to many in the Federation.35 They have distinctive blue skin and white hair, but the most obvious difference lies in their antenna; these are often fixed in place,33 but in some Andorians the antenna can move.36 There is a sub-species of Andorians known as The Aenar, who have much paler skin and are blind. Telepathy is common amongst the Aenar, and they have strict cultural rules against using their abilities to spy on the thoughts of others. The Aenar are strongly isolationist, and very few Andorians have ever managed to meet one although there are some communications between the Andorian government and the Aenar leaders. There is also a strong streak of pacifism in Aenar culture.37

The Andorians and Vulcans have a somewhat troubled history; in the mid 21st century the Andorians terraformed a Class-D planetoid which they named Wehtaan. When they refused to allow the Vulcans to inspect the colony the Vulcans responded by forcibly evacuating the colony. In 2097 the Vulcans officially claimed the planetoid, which they named Paan Mokar'a in 2097. Hostilities continued until 2152 when Captain Archer managed to negotiate a peace deal between the two sides.36

The Andorians have also had considerable animosity with the Tellarites in the past. In 2154 the Romulans attempted to initiate a war between the two sides by using a drone ship which could camoflague itself as other vessels to attack an Andorian warship.38 The plot failed thanks to Captain Archer and the NX-01, who created a temporary alliance between the two sides and the Humans and Vulcans. In the aftermath the Andorians and Tellarites at last began to talk through their problems.39 Both sides also attended the inter-species conference held on Earth in 2155, which aimed to build a true alliance between many of the planets near Earth.40

In the Mirror universe, Andorians were one of the subject races which the Terran Empire subjugated during the first century after it achieved starflight. Andorians continued to design and build their own ships; in 2155 many of these took part in the rebellion which threatened the Empire that year. The rebellion was quelled in large part thanks to the advanced technology the Empire obtained from the USS Defiant.41

Journey to Babel
Angelian42 Inhabitants of the planet Angel One. The females of Angel One are larger and stronger than the males. Culturally the planet is a Matriarchy, with males generally regarded as being incapable of dealing with serious or important matters. When some male Federation citizens were stranded on the planet in the 2360s they at first found the culture there to be enjoyable. However over time they came to dislike and fight against the way males were treated. In 2364 the Enterprise-D visited the planet and convinced the leader of Angel One to allow the men to live in exile in a remote region, rather than executing them.42 Angel One
Angosian43 Prospective Federation members, the Angosians modified their own citizens to make them more militaristic during wartime.43 The Hunted
Ankari44 Delta quadrant species which assisted the Equinox. The Ankari worshipped nucleogenic life forms from another dimension.44 An Ankari helped Voyager to contact the nucleogenic life forms in 2376.45 Equinox, Part 1
Annari46 The Annari are a Delta Quadrant species at war with the Kraylor as of 2377.46 Nightingale
Antaran47 Species which engaged in several wars with the Denobulans, the last ending around 1853. Over 20 million Antaran casualties resulted from the conflicts. Many Denobulans and Antarans retain a great hatred for one another, and there was virtually no contact between the two species for six generations prior to 2153. During this time there had been some small moves towards greater understanding.47 The Breach
Antarian4 The Antarians were one of several species which were at war with one another for a hundred years. They presided over a regular race held to commemorate the peace; in 2377 Voayger's Delta Flyer took part in the race.4 Drive
Antedean48 Piscine species who travel in a dormant state to avoid the stress of space flight.48 Manhunt
Antican49 Potential Federation members in 2364, the Anticans were from the same system as their enemies, the Selay.49 Lonely Among Us
Arachnid50 Creature which Barclay de-evolved into50 Genesis
Arbazan51 Federation member species. An Arbazan ambassador visited Deep Space Nine in 2369. They have a tendancy to take offence easily.51 The Forsaken
Arbazon Vulture52 A predatory bird. Odo was once exhilarated by the experience of imitating an Arbazon Vulture.52 The Search, Part 2
Arcadian53 An Arcadian was present at the hearing which demoted Admiral Kirk back to Captain in 2286.54 The Art of Star Trek

Archer IV Glow Fly55 A small flying creature native to Archer IV. The creatures were discovered by the NX-01 on its mission of exploration in 2151.55 Strange New World
Ardanan56 Species native to the planet Ardana. The Ardanans were reknowned for their abilities with antigravity technology, as showcased by the floating 'cloud city' of Stratos, which was called the finest known example of sustained antigravity technology.56 In the 23rd century Ardanan society had two principle castes. The elite dwelled in Stratos, where they devoted themselves to artistic and philosophical pursuits. The bulk of the population were referred to as Troglytes; these toiled on and below the surface to support Stratos, living in poor and often dangerous conditions. It was believed that the Troglytes were mentally inferior to the Stratos dwellers, incapable of appreciating art and beauty. In fact this was the result of exposure to harmful gases released as part of the Zenite mining operations which most Troglytes worked at. Great tensions developed between the two groups, which came to a head during the visit of the USS Enterprise in 2269. Captain Kirk was able to convince the two sides to begin to come to a peaceful resolution of their differences during his time on the planet.56 In 2152 the NX-01 encountered a Retellian cargo ship which used power regulators from an Ardanan shuttle. The regulators were not considered to be sufficient for their purpose by Commander Tucker.57 The Cloud Minders
Argalan58 Species from the planet Argala in the Delta Quadrant. The Argalans preferred a cold climate, something the Nyrians found hard to tolerate. At least one Argalan ship was hijacked by the Nyrians.58 Displaced
Argelian59 Sentient humanoids, native to Argelius II. After a "great awakening" in 2067 the Argelians became highly headonistic, devoting themselves almost entirely to pleasure. Some Argelian women were posessed of mild empathic abilities, although this was largely a lost art by the 2260s.59 Wolf in the Fold
Argosian60 Sentient species; Sisko once almost got into a fight with one60 Dax
Argrathi61 The Argrathi punished criminals by implanting the memory of a long prison term into their mind in just a few seconds.61 Hard Time
Ariolo62 Federation member species.62 Two of this species were present in the Federation council chamber in 2285 during the Cetacean crisis.54 Star Trek IV Sourcebook Update
Arkarian63 The Arkarians assisted in running the Remmler array. Several of them assisted the terrorist attack on the Enterprise-D.63 Starship Mine
Arkarian Water Fowl63 Creature noted for its unusual mating habits63 Starship Mine
Arkenite54 An Arkenite served at Starfleet command during the alien probe emergency of 2286.54 Star Trek IV : The Voyage Home
Arkonian64 Species encountered by Humanity in 2152. The Arkonians had a reputation for being difficult to deal with, but Captain Archer managed to maintain civil relations with them. They can emit a liquid which is highly effective in healing wounds. They drink a liquid which is poisonous to Humans, and do not handle high temperatures as well as Humans do.65 In 2152 an Arkonian was one of the prisoners aboard the Enolian transport which Captain Archer and Commander Tucker were held on.66 Various Enterprise episodes
Armus67 In 2364 Counsellor Troi was travelling back to the Enterprise-D in a shuttlecraft when it was pulled of course by a mysterious force which crash-landed it on Vagra II. Troi survived the crash, but when the Enterprise came to her rescue the ship was unable to beam her up due to a strange energy on the planet. The ship dispatched an Away Team, but on arrival the team was prevented from approaching the crashed shuttle by a strange being. The life form initially took the form of a viscous black liquid which lay on the surface. It blocked access by interposing itself between the Away Team and the shuttle, then assumed a slightly more Humanoid form. The creature communicated with the away team verbally, calling itself Armus. It refused all requests to allow the Away Team to help Troi, and when Lieutenant Yar attempted to walk past it Armus hit her with some form of energy discharge, killing her.

Armus demonstrated many powerful abilities. It seemed unaffected by phaser fire and was able to manipulate and even transport matter. Armus claimed that it had once been a part of beings not unlike Humans. In the distant past these beings had discovered a way to convert their negative personality traits into a physical skin, which they then shed. These people had subsequently become dazzlingly beautiful and had departed their home planet, leaving the 'evil' material - Armus - behind.

Armus made several attempts to terrorize the Enterprise crew, but each time was frustrated by their total refusal to assist it. Eventually they realized that the energy field preventing transport was reduced in strength each time Armus was frustrated; Captain Picard beamed down and confronted Armus, provoking it into a rage of such magnitude that the ship was able to beam its crew back.

The Enterprise posted warnings to prevent any vessels from approaching Vagra II and abandoned Armus there. It's fate is unknown, but there is no reason to suppose that it is not still on the planet.67
Skin of Evil
Arretan An ancient species, the Arretans explored space some 600,000 years ago. They visited many planets, possibly including Vulcan. Over time they became incredibly advanced and powerful. Each Arretan was capable of amazing mental feats - they could control technology at a distance, read thoughts and speak telepathically to others, influence their emotions and memories in precise ways, inflict pain on other beings merely by thinking about it, and much more. Perhaps most impressive, they could transfer their own consciousness to any body or machine of sufficient complexity, although the strain of bearing an Arretan consciousness was extreme.68

In time the Arretan's power grew to such an extent that they came to consider themselves as Gods. However they became divided, and began to war amongst themselves. They would later claim that the war was fought with such powers, and for such reasons, that Human beings could not possibly comprehend either one. The war resulted in the virtual extermination of their species, leaving only three survivors as disembodied minds resting in small spherical containers deep under the ruined surface of their planet.68

In 2268 the Enterprise fell under the influence of the surviving Arretans and was brought to the ruined planet. The leader of the survivors, Sargon, asked Captain Kirk and his offers to host the surviving Arretans long enough for them to construct machine bodies for permanent residence. Kirk agreed, but the plan went awry when one of the Arretans, Henoch, betrayed the others in an attempt to destroy them and remain in Spock's body indefinitely. Sargon was ultimately able to overcome Henoch but the conflict convinced him that there was no place for beings of their power in the present day, and he and Thalassa chose to end their lives.68
