Honduran fruit-eating bat Neotropical bats, which typically range from 10-85 g. It displays the characteristic lack of tail and narrow patagium seen in fruit bats, and also has a very densely furred uropatagium, which distinguishes A. hirsutus and A. inopinatus from many other species in the genus. Like most bats, they are nocturnal, roosting during the day, and use echolocation for navigation at night. The bats are in the family Phyllostomidae, also referred to as the New World leaf-nosed bats. This group tends to have distinct pointed, or "leaf shaped" snouts which assist them in echolocation. The Honduran Fruit Eating bat has a
Robert Galambos generate and hear sounds an octave higher than can be heard by humans and other animals. Experiments they conducted used methods developed by Hallowell Davis to monitor the brains of bats and their hearing responses as they navigated their way past wires suspended from a laboratory ceiling. They showed how bats used echolocation to accurately avoid obstacles, which they were unable to do if their mouths or ears were kept shut. Griffin coined the term "echolocation" in 1944 to describe the phenomenon, which many physiologists of the day could not believe was possible. Using electrodes implanted in the brains of
