After successfully swooping down on its prey, a fringe-lipped bat, Trachops cirrhosus, looks like a swamp monster as it stretches a túngara frog during a dramatic launch back into the air. This picture was taken at the Gamboa Bat Lab of the Smithsonian Tropical Research Institute in Panama. Using flight cages at the Gamboa Bat Lab, behavioral biologists are able to effectively study sensory and cognitive ecology of Neotropical bats and their prey. This photo was taken inside one of the flight cages, using a bat that had been caught nearby in the wild, studied for a few days, and then released in good health back into its same wild territory
