About the Pen-tailed Treeshrew

The pen-tailed treeshrew (Ptilocercus lowii) is a treeshrew of the family Ptilocercidae native to southern Thailand, the Malay Peninsula, Borneo, and some Indonesian islands. It is the only living species in the genus Ptilocercus. All other treeshrew species are grouped in the family Tupaiidae.

The pen-tailed treeshrew occurs from southern Thailand and the Malay Peninsula to northern Sumatra, Siberut, Bangka Island and northwestern Borneo. It inhabits foremost primary forest up to an elevation of 1,200 m (3,900 ft), where undergrowth is dense.

Pen-tailed treeshrews studied in Malaysia spent several hours per night consuming naturally fermented nectar of the bertam palm. This nectar contains one of the highest alcohol concentrations of all natural foods. The pen-tailed treeshrews did not show any signs of intoxication, although they frequently consumed large amounts of this nectar, equivalent of 10–12 glasses of wine adjusted to body weight with an alcohol content up to 3.8%. Measurements of a biomarker of alcohol dehydrogenase suggest that they may be metabolizing it by a pathway that is not used as heavily by humans. Their... Wikipedia →
