Abstract: 

Under water sound playback experiments were undertaken to determine if gray whales would avoid the sounds of killer whales. When presented killer whale "screams" from an underwater projector, the gray whales swam directly away from the sound source. Controls of no intended stimulus, pure tones, and random noise generally failed to induce an avoidance. It appeared that gray whales localized the killer whale sounds and avoided them as a sign of potential danger.
