Ysalamir

Ysalamiri were furry, lizard-like tree-dwellers (on average, about 50cm in length) native to the planet Myrkr, most known for their ability to repel the Force by creating a Force-neutral bubble. This ability evolved in response to predation by the Force-sensitive vornskrs. Many ysalamiri grouped together would expand their Force-neutral bubble by varying distances – sometimes by kilometers.

Anatomy
"I hate that thing."

- Jaina Solo, complaining about the ysalamir's ability to repel the Force

Adult ysalamiri grew up to 90 or 120 centimeters and hatched their young from bubble-like eggs.

Ysalamiri sank their claws into the Olbio trees on which they lived and drew nutrients. It was very difficult to remove a ysalamir from its tree without killing it, although Talon Karrde's smugglers found a way, enabling Grand Admiral Thrawn to do it as well. Thrawn used ysalamiri for defense by attaching them to a back harness or a nutrient frame which allowed him and his men to remain safely inside the ysalamiri's Force repelling bubble. He used this trick to gain the attention of cloned Dark Jedi Master Joruus C'baoth and accelerated the Spaarti cloning process without the usual side-effects (which occurred when similar Force imprints interfered with one another).

Ysalamiri did not actually negate the Force; since all existence was infused with Force energy, this would not be possible. Rather, they projected a bubble inside which users were unable to exert any influence over the Force. A single bubble measured up to 10 meters in diameter; large groups of ysalamiri could extend their collective bubble by kilometers, but only in great numbers.

Miriskin was a commodity supposedly made from ysalamir skin.

Ysalamiri in culture
Having long admired the tenacity of the ysalamiri, the Jedi Order named a form of lightsaber combat, Makashi, after the creature.

Tyber Zann was known for keeping ysalamiri in cages to prevent Force users from being able to cause too much damage.
