The jajtspat was an animal native to Kwejian. The Kowolian nightsprey survived by nesting on the backs of jajtspats, though it caused no harm and the jajtspat remained unaware of their presence.
In 3190, Cleveland Booker described the relationship of the Kowolian nightsprey to the jajtspat to Ruon Tarka while suggesting his plan of attaching his ship to USS Discovery without being detected. (DIS: "Rosetta")
