Alien physiology

Alien physiology represents special physical and/or biological adaptations that sets a racial group apart from that of an Earth human. Alien physiology differs from race to race and may include increased or decreased physical aptitudes based upon the gravity of the race's point of origin. Some races may also possess natural abilities, such as flight, which may seem like a super-power to those unfamiliar with the race in question. Other aptitudes of a race-specific alien physiology may also include increased mental aptitudes and/or psionic abilities.
