Not much is currently known about the ka'ala'kai. These gigantic, green creatures seem unaffected by life in a vacuum; their systems for mobility aren't yet completely known, as they seem to be able to ignore the effects of gravity (or no gravity) at will. So far, ka'ala'kai have only been sighted and recorded via long-distance telescopes pointed at abandoned planets, moons, meteors, and comets. Most sightings have corroborated the theory that ka'ala'kai are matriarchial nomads that travel from celestial body to body with their children, and that adult ka'ala'kai separate from the pack when they have children of their own.
