Predation by killer whales ( Orcinus orca ) and the evolution of whistle loss and narrow‐band high frequency clicks in odontocetes
Abstract A disparate selection of toothed whales (Odontoceti) share striking features of their acoustic repertoires including the absence of whistles and high frequency but weak (low peak‐to‐peak source level) clicks that have a relatively long duration and a narrow bandwidth. The non‐whistling, hig...

Abstract A disparate selection of toothed whales (Odontoceti) share striking features of their acoustic repertoires including the absence of whistles and high frequency but weak (low peak‐to‐peak source level) clicks that have a relatively long duration and a narrow bandwidth.
