A party animal

This is a pen-tailed tree shrew, Ptilocercus lowii, a Malaysian critter that weighs only 47g but can drink the pound-for-pound equivalent of nine glasses of wine without any ill-effect when it sups on the alcoholic nectar of the bertam palm. While there are other species that drink the nectar - the slow loris, Nycticebus coucang, the common tree shrew, Tupaia glis, and the plantain squirrel, Callosciurus notatus - the shrew is the Oliver Reed of the bunch.
