Panama. The phylogenetic relationships obtained in the 2007 study are given below; these were supported by similar studies in the following years. Physical characteristics The kinkajou has a round head, large eyes, a short, pointed snout, short limbs, and a long prehensile tail. The total head-and-body length (including the tail) is between , and the tail measures . Its mature weight ranges from . Females are generally smaller than males. The short, rounded ears measure . The eyes reflect green or bright yellow against light. The long, thick tongue is highly extrudable. The snout is dark brown to black. The claws are sharp and short. The coat color varies throughout the range and at different times of the year. Several shades such as tawny olive, wood brown, and yellowish tawny have been reported for the upper part of the coat and the upper side of the tail, while the underparts and the lower side of the tail have been observed to be buff, tawny, or brownish yellow. Some individuals have a black stripe running along the midline of the back. The color seems to become lighter from the south to the north, though no seasonal trends have been observed. The fur is short, woolly and dense. Hairs are of two types - light yellowish and darker with brown tips. The darker hairs reflect light poorly relative to the lighter ones, often creating an illusion of spots and dark lines on the coat. The tail is covered with thick fur up to the end. The kinkajou is distinguished from other procyonids by its small, rounded ears, extensible tongue, and prehensile tail. Olingos are similar enough in appearance that many native cultures do not distinguish the two. Compared to olingos, kinkajous are larger, have foreshortened muzzles, and lack anal scent glands (in addition to the previously described differences). The binturong, a Southeast Asian viverrid, has similar limb proportions and is the only other carnivoran with a prehensile tail. The kinkajou resembles neotropical monkeys in having a prehensile tail and big, forward-facing eyes, but has a different dentition and heavy fur on the soles of the feet. Range and habitat Kinkajous range from east and south of the Sierra Madre in Mexico, throughout Central America to Bolivia east of the Andes and the Atlantic Forest of southeastern Brazil. Their altitudinal range is from sea level to 2500 m. They are found in closed-canopy
