pest control. One is briefly seen in Return of the Jedi outside Jabba's palace. It catches an animal with its tongue, swallows it, and burps. Many consider this to be the first major introduction of George Lucas's childish humor into Star Wars movies, and a prelude to Jar Jar Binks. They are sometimes confused with frog-dogs. WraidWraids are large, lizard-like creatures that live and are hunted for their armored head plates on the desert planet of Tatooine. There is also a subspecies on Korriban. WyrwulvesWyrwulves are six-legged, dog-like animals that were in fact the children of the Codru-Ji race. When a wyrwulf reaches puberty, it encases itself in a cocoon, from which a Codru-Ji adult emerges several weeks later. They can be found on Munto Codru. Y YeltzYeltz is an amphibious species that resides in the artificial outpost planets of the Lupania ring. No one but Yaddle has seen the creature, and thus it is still regarded as a legend. They are thought to possess the ability to turn transparent under water. When submerged, they are fearsome predators, but when on-land, they are shy and tamable. YeometYeomets are trash-eating quadrupeds that live on artificial habitats, like space stations or large capital ships. They are able to eat almost any form of matter, thanks to a special digestive enzyme triggered by strong electromagnetic radiation. They carry disease. Yorik coralYorik coral was the primary shipbuilding material of the Yuuzhan Vong. It was grown on-planet in the shape of a ship. Later, symbiotic creatures were implanted or grown within it to form the ship's functions. The completed yorik ship had a nervous system that controlled and coordinated the various functions, and a circulatory system that sustained them. YsalamiriYsalamiri are furry salamander-like creatures that live on Myrkr. They have the unique property of repelling the Force, rendering all Force powers within their sphere of influence void; for this reason, they are prominently used by Grand Admiral Thrawn in his campaigns against the New Republic. The supposed reason for the Force bubble is that it acts as a way to hide from the other unique carnivores of Myrkr that use the Force to hunt down prey, such as the vornskr. The term "bubble" is particularly apt because, like water bubbles underwater, multiple ysalamiri's bubbles reinforce each other instead of overlapping. Because of this, large sections of Myrkr are completely removed from the Force. Z ZakkegZakkegs
