Whales may eat ocean plastic due to sound echoes mimicking prey, a new Duke study finds.
A Duke University Marine Lab study finds whales may ingest ocean plastic because the debris produces echoes that mimic or exceed the acoustic signals of natural prey when hit by whale echolocation.
This sound-based deception, particularly in deep waters, leads whales to mistake plastic for food, increasing health risks.
The research reveals a previously overlooked mechanism by which plastic pollution harms marine mammals, highlighting the need to reduce ocean plastic and understand its acoustic impacts.
