Bolians come from the planet Bolarus IX. They are a race of bald, blue-skinned humanoids with a prominent ridge running down the center of their heads and bodies. Only young females possess any body hair, and that only on their scalps. They evolved from an aquatic race and are still very at home in the water, although they are fully comfortable on land.
Bolians are staunch allies of the Federation. Several have risen to positions of great importance in the Federation and in Starfleet. Many turn their liability of racial curiosity into an advantage by occupying research or investigative jobs. They have only recently made peace with the Moropans, a rival race, although this peace is a fragile one.
