Noise pollution spooks whales the way predators would, study finds

  • Whales appear to react to human-made noise in the ocean, such as naval sonar, in a similar way to which they respond to the sounds of their predators like killer whales, according to recent research.
  • The authors of the study played the sounds of sonar and killer whales when whales from four species were present.
  • The whales responded by breaking off their feeding forays, leading scientists to conclude that noise pollution in the ocean could leave them weaker and more vulnerable to predation.
  • The researchers also suggest that marine mammals in the Arctic may be especially at risk as climate change alters their environment in ways that may make them more vulnerable.
