Genus: Ursus Majorly Lovable
The Wookiees, whose name for themselves translated to the People of the Trees, were a species of hairy bipedal humanoids that were inhabitants of the planet Kashyyyk.
The Wookiees' natural habitats were the dense forests of the planet Kashyyyk (though one source does imply that they were immigrants to this planet). Kashyyyk was covered with massive wroshyr trees, in which the Wookiees constructed their homes and cities. Reportedly, Wookiees were descended from tree-climbing mammals.
They had the ability to easily learn most languages. However, Wookiees lacked the vocal structure to speak anything other than their own languages.
Adult Wookiees were tall, in excess of two meters in height, and were covered with a uniform, mid-length coat of thick hair in various shades of brown. Although albino Wookiees were rare, they were not unheard of. However, such a birth was generally held to be a bad omen, as white hair did not blend in with the earth-tones of their forest surroundings.
Young Wookiees (pups) were large at birth (averaging slightly less than one meter). Wookiees possessed vicious-looking retractable claws for climbing. Female Wookiees had six breasts and gave birth to live-born young, with their gestation period nearly a year long. After birth, a Wookiee grew very fast, fully conscious and able to walk unassisted within one standard year. The average lifespan of Wookiees was around 600 years. In spite of their bestial appearance, Wookiees were highly intelligent and had mastered advanced technology, including hyperspace travel. Wookiees also possessed exceptional skill in mechanical repair. An old saying was "Give a Wookiee a knife and send him into a forest in the morning, and by evening he would have carved you a table to eat dinner on - and a house to put it in."

For the Dar-Win!with your host, Charles DarwinThis is a tough call, but I’m going to say, biologically speaking, that these are the most huggable creatures on the list. Some of the smaller ones, you have to bend down to hug, but here, you just run up with your arms outstretched and if it doesn’t swat you down, you are in for a treat. A hug treat.
