Intelligent Species

1. Confirmed Federation Members - My level for confirmation accepts species whose members are in Starfleet or Federation government unless, as in the case of Worf, Ro Lauren, and Nog, we are specifically told their home planets are not members. For those with stricter standards, I've listed my level of confirming evidence, you can decide for yourselves. There are other confirmed members, see the background aliens in TOS:"Journey to Babel", ST:TMP Rec Deck and San Francisco scenes, and ST:TVH Federation HQ scenes.

Following the list of confirmed members is a list of Applicants to the Federation whose status has not yet been decided.

Following that are two appendices. Alien names made up by the makeup and costume departments for ST:TMP and ST:TVH. As they might be considered "noncanonical", I've only included three in the main list, the Arkenites, Efrosians, and Rhaandarites, as they had speaking roles.

See also the list of species from the Animated Series.

2. Undecided - Some of these entries are filed here merely until I review the relevant episode for confirming evidence. Others truly have no firm statement one way or the other.

3. Non-Members - Additional information for these species will include the location of their home planet if it is not near Federation Space, and the tech level of their native culture. To avoid confusing the layman with the Richer scale of culture, the level of advancement will be put into seven wide categories:


Federation Members


Three unnamed Federation delegations: tall dark-skinned, short gold-skinned and the purple-skinned woman in the background.
The Enterprise was tasked with transporting to Babel 114 delegates, 32 of them ambassadors and - according to one informal estimate, half of them mad at the other half.

Named species below.

Often with blue skin, have small, knobby antenae coming from the top of their heads.
Federation Member.
TOS:"Journey to Babel"
Know cellular regeneration, taught that technique to Garth of Izar.

Several in Starfleet, but one in an officer exchange program - may only have recently joined?
TNG:"Coming of Age", TNG:"A Matter of Honor", DS9:"The Ship"
Have dark irises or large pupils. Empathic and limitedly telepathic. Starfleet Officer, member of a fact-finding mission to DS9, thought of as a core world of the Federation, from which the Dominion could attack Vulcan, Andor, Tellar, and Alpha Centauri, among others.

ST:TNG Technical Manual
The sapience of humpback whales (Megaptera novaeangliae) is uncertain, but an interstellar probe seemed interested in their welfare. They had been extinct, but a pair was transplanted from the 20th century.
Admitted to Federation in the 2260's.
TOS:"Journey to Babel", TNG:"Sarek"
*Corvan[ites] (Corvallan? Corvallen?)
Planet with industrial pollution in the atmosphere.
Stated to be a Federation member in the Encyclopedia. The episode merely mentions the relocation project for the endangered species, the Corvan gilvos (a project difficult on an industrialized world without Contact, but possible for a non-member world that applied for help).
The two alternate spellings above have been used to refer to traders and a freighter, respectively. Possibly variants of the planet name.

MY VOTE: Likely not.
TNG:"The Chase"

MY VOTE: No need to include it.

TNG:"Menage a Troi"
Algolian ceremonial rhythms are in a percussive musical style.
The star Algol has a dark companion which eclipses it as seen from Earth. The periodic variation in brightness is detectable on Earth by the unaided eye. This could be the inspiration for the ceremonial rhythms; there need not be an Algolian race that uses them.

MY VOTE: No need to include it.
A lieutenant (Starfleet?) who threw a drink at a young Benjamin Sisko.

DS9:"The Forsaken", TNG:"Firstborn"
Brains similar to Ferengi.
Homeworld destroyed by Borg.
MY VOTE: As with refugee Bajorans, individuals can be Federation citizens, but the race as a whole (or what is left of it) is not a member.

TOS:"Elaan of Troyius"
Helped by E-D in historical research. Criminal returned to home planet's jurisdiction.

TNG "The Dauphin"
*Angels (?)
A human-looking race. They have been persuing an isolationist policy to prevent changes in their culture.

They have foresaken any technology that would distract from their concentration on life.
Delta Quadrant
VGR:"Ex Post Facto"
TNG:"Thine Own Self"
Wished to remain neutral among the powers bidding for the wormhole discovered in their space.
Catlike, require additional breathing gear in a Class M atmosphere.
TNG:"The Price"
Would have gone extinct when their planet underwent sudden atmospheric dissipation if not for the actions of Nikolai Rozhenko, Federation academic performing a cultural study on the planet.
Delta Quadrant
Actually a collection of species. Presumably there was one species which first modified itself with cybernetic implants. This is likely not Species 125.
An extremely secretive race, protective of their borders. Breen are not empathically detectable by Betazoids and wear sealed, refridgerated suits when off-planet. The Breen homeworld is supposedly a frozen wasteland, but a Vorta (attempting to sow distrust among the Cardassians) claimed to have been there and found it quite temperate.
Delta Quadrant
Attacked several times by the Borg, they are barely holding on to their technology.
A shapechanging race of unknown origin and nature, almost thought to be legendary. One example was found in Klingon space, on Rura Penthe.
*Children of Tamar (sometimes Tamarians)
Have established contact with the Federation.
Galactic Core
This race studies spacefaring cultures by sending out probes that reprogram the subject's technology to bring them to the Cytherian system for cultural exchange. The "god" of Shakari may have been a renegade member of this race.

TNG:"Tin Man"

Genetically engineered warriors of the Dominion. They are created artificially in birthing chambers and reach maturity a few days after emergance. They lack a vital enzyme, and must be supplied with ketracel-white, which also supplies all the nutrients and calories they need.

Presumably Delta Quadrant
Presumably assimilated into the
