Krayt dragon

Krayt dragons were large, carnivorous reptiles that hailed from Tatooine, a desert planet in the galaxy's Outer Rim Territories. They came in two subspecies and, despite their fierceness, were hunted for the precious pearls found in their bodies.

Biology and appearance
Krayt dragons were giant carnivorous reptiles that came in two subspecies: the smaller and more common canyon krayt, and the larger greater krayt. Due to their large size and ferocity, they were the apex predators of Tatooine. Their bodies produced krayt venom, which helped the dragons as an acid in pre-digestion of their food.

Behaviour
Hungry krayt dragons posed a serious threat to the diminutive Jawas, and their cry was enough to ward off the fierce sand nomads known as the Tusken Raiders.

History
Krayt dragons were commonly known for their pearls, bodily concentrations that were considered to be highly valuable.

At the time of the Invasion of Naboo, one krayt dragon had taken up residence in the Laguna Caves on Tatooine, in which rescue teams for the Boonta Eve Classic did not dare to go.
