Wookiees

The Wookiees, whose name for themselves translated to the People of the Trees were a species of tall, hairy humanoids that were inhabitants of the planet Kashyyyk. One of the most noteworthy members of the species was Chewbacca, Han Solo's best friend and co-pilot, who played a vital role in the Galactic Civil War and afterwards. A race of arboreal mammals, the Wookiees lived in treehouses nestled in the canopy of the towering wroshyr trees. Despite their fearsome appearance, they were usually gentle, although they were prone to devastating fits of rage when provoked.

Biology
Wookiees were a tall species of furry humanoids from the planet Kashyyyk, who could grow to a height of nearly three meters. They were covered from head to toe in a thick, shaggy coat of hair with water-shedding properties that notably came in shades of brown, black, gray, and white. The species had two sexes, female and male. The latter grew long beards in adult life. The Wookiees eye color ranged from blue to brown. Wookiees were big eaters, with the average adult requiring 3,500-6,000 calories a day of food.

Wookiees had extendable claws which they used for climbing; using them for anything else violated the Wookiee honor code. Despite their fearsome appearance and volatile temperament, Wookiees were regarded as intelligent, sophisticated, loyal and trusting. When angered, Wookiees were known to descend into a berserker rage. Wookiees had a long lifespan, appearing not to age over a span of fifty years. During their prime growing years, Wookiees were often hungry, forcing them to eat whenever they could. One Wookiee, Lohgarra, lived healthily for centuries—the only distinction being her white fur. They could learn to understand other languages, like Galactic Basic Standard, but they were physically unable to speak them. To those who had not learned to understand Shyriiwook, the Wookiee language, it appeared they spoke in a series of growls and purrs. Although a rare phenomenon, Force-sensitive Wookiees were possible and some joined the ranks of the Jedi, a source of great pride to their people. One such Wookiee was the youngling Gungi.
