The Kowolian nightsprey was an animal native to Kwejian. It nested on the back of a jajtspat to survive, though it was not parasitic as it did not cause any harm.
In 3190, Cleveland Booker described the Kowolian nightsprey's behavior to Ruon Tarka when suggesting his plan of attaching his ship to USS Discovery without being detected. (DIS: "Rosetta")
