Naxeran

The Naxerans were a humanoid race native to the planet Naxera, distinguished by a set of frills extending horizontally on either side of their noses, their ebony-dark skin and gold-colored eyes. However, an off-shoot race, the Weyrie, had white skin and blue eyes. Naxerans did not sleep, nor did they dream. Naxeran society was divided into castes: the G'Dok, or ruling class; the Leahru, or middle class; and the Efram, or working class. These caste names were incorporated into the individuals names.

As of 2336, at least one Naxeran, Thule G'Dok Glemoor, served in Starfleet.
