Ysalamir

Ysalamari are furry, lizard-like tree-dwellers (about 50 cm in length) from Myrkr, most known for their ability to repel the Force. This ability evolved in response to predation by the Force-sensitive vornskrs.

Ysalamari sink their claws into the trees on which they live, and draw nutrients through them. It is very difficult to remove Ysalamari from their tree without killing them, although Grand Admiral Thrawn found a way. He used Ysalamari to great effect, to control the cloned Dark Jedi master Joruus C'baoth and to accelerate the Spaarti cloning process without the usual side-effects, which result from similar Force imprints interfering with one another.
