Functional Convergence in Bat and Toothed Whale Biosonars

P. T. Madsen, A. Surlykke


Echolocating bats and toothed whales hunt and navigate by emission of sound pulses and analysis of returning echoes to form a self-generated auditory scene. Here, we demonstrate a striking functional convergence in the way these two groups of mammals independently evolved the capability to sense with sound in air and water.
