A series of experiments conducted by scientists at the Smithsonian Tropical Research Institute in Panama have revealed that frog-eating fringe-lipped bats (Trachops cirrhosus) are, by necessity, much more discerning diners than previously known. In fact, scientists now know, from the time they begin their attack dive to just before they swallow a frog, the bats are continually evaluating their prey through such sensory modalities as sound, echolocation, touch and taste. A paper on the work is published online in the Springer journal Naturwissenschaften (The Science of Nature). Reference: Page RA, Schnelle T, Kalko EKV, Bunge T, Bernal XE (2012).
