Dulok

Duloks were an aggressive sentient species native to the moon of Endor, where they lived in swamps. They would emerge from the swamps to hunt lantern birds and the sentient Ewok species who they shared the moon with.

Behind the scenes
Duloks were created for The Adventures of Teebo: A Tale of Magic and Suspense, a Star Wars Legends novel written and illustrated by Joe Johnston and released in 1984. They also featured prominently as villains in the animated television series Star Wars: Ewoks, which was also part of the Legends continuity. The species was confirmed to be canon in 2015 by the reference book Ultimate Star Wars.
