Krayt Dragon

Nearly 150 feet long, krayt dragons (CRATE DRAG-uns) can live to be up to 100 years old, and weigh over two tons. On top of their colossal dimensions, their teeth and spines secrete fatal venom. This carnivourous, reptilian, nonsentient species was made up of two species, the first, the canyon krayt dragon, possessed the aforementioned size. The second species, however, was much bigger and much less common: this krayt can measure over 300 feet, and needs all ten legs to support all that weight. C-3P0 walked past a greater krayt dragon spine and skull at the beginning of A New Hope, after he separated with R2-D2, who insisted upon going another way. Greater krayt dragons usually hunt sarlaccs and banthas, and, like all other krayt dragons, they develop a pearl in their gizzard; pearls from greaters are bigger and thus more valuable than those from canyon krayts. These dragon pearls can also be used by Jedi, after shaped, as focusing crystals--the crystals that focus the blade in a lightsaber. The weaknesses of krayts are few, but undeniably there: krayts have trouble with two-dimensional images, and sometimes react to shadows and the like. Also, a shot from a skilled gunman can, through the weak sinus cavity, reach the brain, killing the dragon instantly. Before a Sandperson could be accepted as an adult in the tribe, they were abandoned in the desert and not allowed back in until they had killed a krayt. Also, Jawas brave and successful enough to obtain krayt bones, which they believed to possess magical properties, were highly regarded among their people. The skeleton used in the filming of A New Hope was left at the site after the scene was shot, and when the crew for Attack of the Clones visited the Tunisian Desert, where they had left the fake skeleton, it was still there. Isn't that cool?
