Krayt dragon

The krayt dragon was a large carnivorous reptile native to Tatooine.

Characteristics and species
Krayt dragons grew continuously throughout their lives to an average length of 45 meters and weight of 20,000 kilograms. They could live to be 100 years old and did not weaken appreciably with age. An ancient krayt dragon was the oldest and biggest of all krayt dragons. They could be found on the highest mountains of Tatooine.

A fierce hunter, the krayt dragon became an important part of indigenous cultures on Tatooine. The krayt dragon was thought by some xenobiologists to have descended from the Duinuogwuin (also known as Star Dragons). Although no substantial evidence was offered in support of a connection to the Duinuogwuin, the krayt dragon was a proven relative of the smaller kell dragon. In honor of the beast's sheer power and ferocity, the Jedi Order named the Shien and Djem So form of lightsaber combat "The Way of the Krayt Dragon."

The only semi-sentient species known to hunt the krayt dragon is the fabled sand demon.

When summer mating season began, the howls of krayt dragons filled the canyons of Tatooine. The collection of frenzied, mating beasts scared even the mightiest Sand people away. Obi-Wan Kenobi mimicked a krayt dragon hunting cry when he scared the raiders away from Luke Skywalker in 0 BBY.

Young Sand people would hunt krayt dragons in an initiation rite to prove themselves as warriors.[2]

The krayt dragon had a set of sharp teeth used for capturing prey, but relied on ingesting stones to grind the food through a series of gizzards into a digestible state. Food would be crushed by the stones tumbled in the gizzards by stomach muscles, grinding food into pulp and turning boulders into smooth stones. The resulting stones, known as dragon pearls, were a valuable commodity among jewelers. The pearls could also be shaped and tuned by Jedi to be used as focusing crystals in their lightsabers. Krayt dragons instinctively go to the Krayt Graveyard when they are about to die.

Krayt dragons were heavily attracted to areas that were strong in the Force, especially the dark side. Some Sith artifacts, like the Tatooine Star Map, were guarded by krayt dragons.[3]

In spite of their awesome power, krayt dragons did have weak and exploitable biological characteristics. Firstly, krayt dragons had trouble resisting the allure of the prey of the Dune Sea, specifically the Bantha. Secondly, they had difficulty discerning two-dimensional images, often attacking shadows. Thirdly, a well-placed blaster shot could bore right through the weak sinus cavity of a krayt dragon, hitting its brain and killing it instantly.

The krayt could also secrete a lethal venom, either through its teeth or its spines. Although its nature is unclear, numerous underworld characters such as Bib Fortuna have admitted to using the substance to kill enemies.

Although some holofilms, such as the holothriller Luke Skywalker and the Dragons of Tatooine, depicted krayt dragons breathing fire, they are in reality incapable of doing such a feat.

Species
At least two species and several subspecies of krayt dragons existed.

The canyon krayt was a common species of krayt dragon that lived in the rocky caves and canyons of Tatooine's desert ranges. More often than not, the term "krayt dragon" referred to this lifeform. Patterns of horns and spikes appears to have varied from individual to individual. At least one canyon krayt was noted to have a two pronged tail.

The greater krayt, was a rarer, larger species of krayt dragon, known for its tremendous size and continual growth over time. Creatures of near legendary status, greater krayt dragons had ten legs, measured at least 100 meters from snout to tail tip and had the ability to move through or on Tatooine's desert sand. Greater krayt dragons attacked with their massive jaws or whip-like spike-tail, using their claws only to move through the sand.
