Early Kisa evolved from an amphibian with marsupial-like reproductive system. They are now squat-looking 1.5 metre tall bipeds, with two trunk-like eyestalks. Around these stalks is a scattering of sensory bubbles that pick up scent, sound and other inputs. Two optical pods face down at the ends of their eyestalks. Four-fingered hands feature long and delicate-looking digits.
Originally the Kisa diet consisted of various forms of algae, but today they are vegetarian connoisseurs. The Kisa have been developed by the Soro to be an engineering species.
