Acamarians are a generally peaceful race with a history of violent clan wars. Physically, they can be distinguished by a vertical crease in the center of the forehead. A splinter group, known as the Gatherers, composed of members of various Acamarian clans who opposed the peace treaty for approximately 100 years, was eventually repatriated into Acamarian society.

Aenar government, such as it is, has little structure; leaders of Aenar society are chosen as the need arises, usually when contact with outsiders is called for. The Aenar are usually considered to be just a different ethnicity of the Andorian race and not an utterly separate species.

The Aenar population is approximately 11,000 in size and they inhabit the polar region of their world. Andorians believed the Aenar to be mythical creatures before their existence was confirmed circa 2104.

Based on Talla, Shran's daughter from "These Are the Voyages...", it has been speculated that hybrids of an Andorian and an Aenar would be a greenish color, perhaps explaining the greenish Andorian seen in Star Trek: The Next Generation.

Felons are kept in an isolated spacegoing station — as the U.S.S. Voyager's Paris and Kim discovers when wrongly sent there. Pardons or rehearings in convictions and sentencing are never heard.

Non-canon: a novel trilogy, Star Trek: The Q Continuum shows that the Angosians have had some success in later efforts to reintegrate the soldiers, as one now serves on the Enterprise-E.

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 42859.2 when 2 Antedeans tried to sabotage their planet's Federation membership conference on Pacifica with ultritium concealed in their garments.

Nothing has been revealed about them in dialogue, so their backstory (by Fred Phillips and Robert Fletcher) is considered semi-canon.

One of James T. Kirk's earliest commendations is the Palm Leaf of Axanar Peace Mission, following the Battle of Axanar; although the exact nature of the conflict is unrevealed, it is revealed in the episode "Whom Gods Destroy" that Starfleet Captain Garth of Izar achieved a great victory on behalf of the Federation, and his strategies became required reading at Starfleet Academy (since Kirk himself studied these strategies, the Battle of Axanar must thus have occurred well before Kirk entered Starfleet Academy in 2250, which was itself almost 20 years prior to "Whom Gods Destroy"). Kirk claims that the Axanar Peace Mission "topped [Garth's victory] with a greater one" and preserved the civilization that made Spock and himself "brothers", implying that the mission may have contributed to healing a serious rift in the Federation at that time.

This group of Ba'ku followed a simple way of life and disdained the use of technology. (As shown in the film Star Trek: Insurrection, however, the Ba'ku still possessed some form of technology and the ability to use it in emergencies, since they had attempted to repair the damaged Data.) At first the Ba'ku were unaware of the metaphasic radiation in the planet's rings, which caused their aging process to significantly decelerate, although it was later discovered and cherished.

The Ba'ku society consisted of strong bonds between each individual as there were less than a thousand living in a village. Their simpler way of life eventually prompted some of the younger Ba'ku villagers - who wanted to explore the galaxy with offlanders - to rebel against their elders, and an attempt was made to take over the village. When they were unsuccessful, they were exiled and eventually became the Son'a people.

In 2375 peace on the Ba'ku planet was restored, and several members of the Son'a returned to their families.

Perhaps purely by coincidence, "Bandi" was the name of a vaguely ursine empathic parasite in an early Star Trek story premise by David Gerrold, who was involved in the development of Star Trek: The Next Generation, and who novelized "Encounter at Farpoint".

Benzites possess smooth, hairless skin; it may range in color from bluish-purple to green-blue. A thick protrusion of the Benzite skull extends down over the face, displaying a prominent nasal lobe and brow. Two fish-like barbels droop down from above the upper lip. Benzites are highly resistant to poisons and other noxious substances. They can digest and derive nutrition from almost any organic compound. All Benzites from the same geostructure are physically similar, so much so that they are indistinguishable to a non-Benzite.

The Bolians have been active members of the Federation since 2320. Aside from contributing to the ranks of Starfleet they have a delegation within the Diplomatic Corps. In 2366, the Bolian government was maintaining an uneasy truce with the Moropa (TNG: "Allegiance").

The Bolians are known to make a crystal steel that is highly prized. They also own and operate the famous Bank of Bolius. In 2373, the Bolian government authorized the Ferengi Gaming Commission to manage their gambling emporiums.

During the Bolian Middle Ages the Bolians developed the medical philosophy known as the "Double Effect Principle" about euthanasia. This form of assisted suicide states that while euthanasia has the effect of relieving suffering it also has the effect of causing death. Bolian marriages often involve more than two members. Any additional spouse is referred to as a "co-husband" or "co-wife", respectively. Bolian blues is a highly appreciated musical genre among Federation species.

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") and the infiltration, usage of and destruction of a Borg transwarp hub (a critical part of their intergalactic menace) by the USS Voyager ("Endgame")
