in the Star Trek continuity
Tellarites are from the planet Tellar, in the 61 Cygni star system. Tellarites are a vaguely porcine race, with portly statures, pig-like snouts, and hands that have three stubby digits.
Argumentative and stubborn, Tellarites are not the most well-liked people in the galaxy, but they make skilled diplomats and engineers.
Tellarites are a founding member of the United Federation of Planets.
