The ringtail (Bassariscus astutus) is an arboreal (i.e. tree dwelling) small mammal and an excellent climber. A relative to the raccoon, these little fellas can rotate their hind feet 180 degrees which allows them to descend from trees, rocks, and cliffs head-first and without the use of their claws. Ringtails have also been documented performing other cool mountaineering moves such as chimney stemming, ricocheting, and power leaps.
