DOI: 10.1103/PhysRevLett.103.0387010031-9007http://hdl.handle.net/10919/24518The biosonar system of bats utilizes physical baffle shapes around the sites of ultrasound emission for diffraction-based beam forming. Among these shapes, some extreme cases have evolved that include a long noseleaf protrusion (sella) in a species of horseshoe bat. We have evaluated the acoustic cost function associated with sella length with a computational physics approach and found that the extreme length can be predicted accurately from a fiducial point on this function. This suggests that some extreme cases of biological morphology can be explained from their physical function alone.application/pdfen-USIn CopyrightHorseshoe batEcholocationFerrumequinumEvolutionNoseleafPhysicsAcoustic Effects Accurately Predict an Extreme Case of Biological MorphologyArticle - Refereedhttp://link.aps.org/doi/10.1103/PhysRevLett.103.038701Physical Review Lettershttps://doi.org/10.1103/PhysRevLett.103.038701
