Tree Shrew Lavatory

Some carnivorous plants have a rather creative way of getting their nutrient fix. The Nepenthes lowii pitcher plant in Borneo attracts tree shrews(usually Mountain Treeshrew / Tupaia montana) with sweet nectar. If they need to relieve themselves while eating, the shrews are perfectly positioned on the pitcher plant. Gross? Not for the plants, which get between 57 percent and 100 percent of their nitrogen from shrew poop.
