A hairless, pale-skinned Federation species seen in Star Trek: The Motion Picture, said in production notes to make all their clothing from a substance their own bodies produce.
The Aaamazzarites are slender humanoids with chalk-pale, hairless heads and prominent brows, dressed in layered yellow and cream robes with broad collars. They are one of the non-human peoples visible in the Federation of the 2270s.
They appear in Star Trek: The Motion Picture, at the Starfleet air tram station in San Francisco and in the crowd of crew on the Enterprise recreation deck as Kirk explains the V'Ger threat.
Neither their name nor any detail about them is given in dialogue. Robert Fletcher's costume notes call them Aaamazzarites, also Therbians, from the planet Aaamazzara, and explain that everything they wear and much of what they use is spun from a chemical secretion of their own mouths, rather as an insect makes a cocoon.
