The arms ended in furless, three-fingered, dark pink hands and the legs ended in furred two-toed feet.
Members of the species had 8 limbs: six fully functional arms and two legs. Shorter and stockier than the average human, Harch weighed about the same due to a tough exoskeleton that was coated in hair ranging from brown to pale gray. With physiology derived from arachnid ancestors, the sentient Harch species were genetic cousins of the Aqualish.
