Carnivory
The pitchers of N. attenboroughii are open to the elements and thus often completely filled with fluid. This fluid is viscous in the lower part of the pitcher and watery above, forming two fractions that do not mix. The upper fraction supports populations of pitcher infauna, particularly mosquito larvae, and the pitchers of this species may benefit from both the usual capture of prey as well as the detritus produced by organisms living within the pitcher fluid.
In the latter half of 2009, this taxon received a great deal of publicity in the national press of various countries as a sensational new plant that catches and kills rats. Whilst certainly large enough to trap rodents, no rodents of any kind have yet been observed within the pitchers of this species, as indicated in the type description and through subsequent clarification by the author, who suggests that should rodents be captured by the plant, it is likely to be through misadventure rather than by design; instead, large bugs and flying insects appear to be the usual prey.
In October 2012, a dead shrew was found in a pitcher of Nepenthes attenboroughii during a return expedition to Mount Victoria.
