Andorians are natives of the planet Andor (known as Fesoan to the natives). They were one of the founding members of the UFP. Andor is a hot, dry world with very little surface water, and a gravity of 0.90 T. Physically, they are blue-skinned humanoid bipeds with white hair and knobby antenna on the crown of their heads. They lack visible ears. They have characteristics of both mammals and insects. They are all ambidextrous. Like mammals, they are warm-blooded, bear their young live, and have an internal skeletal structure to which their muscles attach. Like insects, they have a limited exoskeleton that gives them extra damage resistance from attacks.
