Scandentia (treeshrews)
Tupaia tana
EOL Text
Tupaia tana means ‘ground squirrel’ in Bahasa Indonesian. Recent research suggests that tree shrews share a common ancestor with primates and could help in piecing together the evolutionary history of Homo sapiens.

This species is found in Malaysia (Sabah, Sarawak, Banggi) and Indonesia (Kalimantan, Sumatra, the Batu Islands, Lingga Islands, Bangka, Tambelan, Serasan) (Helgen, 2005). It appears to be absent from the south coast of Borneo, with no records from Sebangau and Tanjung Putting. Probably occurs to 1,500 m, but more common up to 1,200 m (K.H. Han pers. comm.).

On average, Tupaia tana weighs 198 grams and has a head and body length of 22 centimeters. Tupaia tana has an elongated snout that is longer than that found in other tree shrew species. The eyes are large and without lashes and the ears are hairless. The fur of large tree shrews is dark brown on the dorsal side and reddish-orange on the ventral side of the animal. Yellow stripes are present on each shoulder and a distinct black stripe is present down the midline of the back. The tail is bushy and quite short in comparison to the length of the rest of the body and in comparison to the tails of other tree shrews. The color of the tail varies between orange, yellow, and red depending on geographic location. As in most scansorial mammals, large tree shrews possess elongated claws used to hold on to branches and for digging. Canines are well-developed, but the teeth in general are non-specialized. Males and females are similar in size and appearance.
Average mass: 198 g.
Average length: 22 cm.
Other Physical Features: endothermic ; homoiothermic; bilateral symmetry
Sexual Dimorphism: sexes alike
Average mass: 797 g.
