Ykaora Worm

Ykaora worms were very large, worm-like creatures that inhabited the mountains of the planet Hiyllis. Even though the ressemble a worm, they are actually reptiles.

Behavior
They were hostile and known to randomly attack mountain climbers, knocking them off the mountainside and killing them. They fed on a diet of insects, spiders and rare mountain-plants. They were known to live alone, and they were endangered, with only about 25 left as of 5 ABY. It is unknown why they were endangered, as no Hiyllians ever hunted Ykaora worms. They had no legs, but somehow managed to move around in the caves they lived in fairly quickly, for their shape and size.

Appearance
Ykoara worms had a giant earthworm-like body, containing one small brain and two large hearts to pump the blood through the huge body. They appeared to be a gigantic, pale-blue worm with small horns and blunt but big teeth.

Other
Hiyllian Hid Iorana has been known for being attacked by and killing multiple Ykaora worms in his lifetime, and it is treated as a high achievement.
