Tellarite

The Tellarites are a species of humanoids from the planet Tellar Prime. Their race was a foundation member of the United Federation of Planets in 2161.

Physiology
Tellarites had sturdy bodies, their facial characteristics distinguishable from other races by their snout-like noses. Most male Tellarites grew beards, while some Tellarties had hoof-like hands. They also had a higher-than-human body temperature as they felt humans kept their rooms too cold. (ENT: "Babel One")

Tellarites might be porcine in nature, as evidenced by USS Cantabrian security officer Snerl's squealing when a Myhr'an broke his leg in 2372. (Star Trek: The Cantabrian Expeditions: "Catalyst, Part One")

Society
Generally, Tellarites were both impatient and "stubbornly proud" people. (ENT: "United", "The Forge") Unlike the Vulcans, the Tellarites demonstrated strong emotions and enjoyed a good argument. (ENT: "Bounty")

Social interactions amongst Tellarites usually started with a series of complaints, but if they held no complaints, they simply insulted the person. With such a strong, natural ability to argue, Tellarites made good politicians. (ENT: "Babel One") Depsite their argumentative nature, Tellarites were generally trustworthy. (ENT: "Dead Stop")

Tellarites enjoyed mud baths. (ENT: "Bounty")


 * This further supports evidence Tellarites were porcine in nature.

History
By Earth's 20th century, the Tellarites were both warp-capable and in contact with the Vulcans at least, evidenced by a Tellarite freighter receiving a distress call from a Vulcan ship stranded on Earth in 1957 and passing it on to Vulcan High Command. (ENT: "Carbon Creek")

In November 2154, a conference was held on Babel to resolve a long-standing trade dispute between the Tellarites and Andorians. A secret Romulan attempt to deteriorate negotiations between the two parties and further destabilize the region failed, leading to a temporary Human-Vulcan-Andorian-Tellarite alliance. (ENT: "Babel One", "United")

By 2155, this coalition evolved, with talks on Earth being held to possibly establish a Coalition of Planets, the precursor to the United Federation of Planets. The Tellarites participated in these talks. (ENT: "Demons")

In 2161, the Tellarites, along with Humans, Vulcans and Andorians, as well as other races, created the United Federation of Planets, giving Tellarites a seat on the Federation Council and the right to serve as Starfleet officers.
