Mountain Treeshrew (Tupaia montana) at Nepenthes rajah
Mountain Treeshrew (Tupaia montana) feeding at Nepenthes rajah. Recent research has shown the the world's largest pitcher plant Nepenthes rajah is not exclusively carnivorous. Like the related N. lowii, this species attracts treeshrews by secreting nectar on the undersurface of the lid. These animals frequently leave their droppings in the pitcher, which serves as a valuable nitrogen source in their impoverished mountain habitat.
