Toads Eat Bats?

Toads have been known to eat bats, although usually only when they happen upon one opportunistically, said Rachel Page, a researcher at the Smithsonian Tropical Research Institute in Panama who wasn't involved in the present finding. However, some toads and frogs will systematically wait outside of caves and catch bats as they emerge from the roost at night, Page wrote to LiveScience in an email. This has been seen in Australia, she said.
However, bats are not always the victims in this animal-eat-animal world — certain species, like fringe-lipped bats (Trachops cirrhosus), have been known to eat toads.
