  • Scientists have discovered that minke whales can detect high-frequency sounds up to 90 kHz, significantly higher than previously estimated.

  • Minke whales are a type of baleen whale, which are a group of whales that use baleen plates to filter feed on krill, small fish, and other prey

  • This finding suggests that baleen whales, in general, may be more susceptible to anthropogenic noise pollution than previously thought.

  • Anthropogenic noise, such as that from shipping and sonar, can disrupt marine mammal behavior, communication, and potentially cause hearing damage.

  • Setting clear thresholds for noise impact on marine mammals is difficult due to their diverse responses to noise.

  • The study employed a novel catch-and-release method to conduct auditory evoked potential (AEP) tests on minke whales.

  • The findings challenge the traditional understanding of baleen whale hearing, revealing their ability to detect high-frequency sounds.

  • Overall, this groundbreaking research highlights the need for further investigation into the impact of anthropogenic noise on baleen whales and other marine mammals. 

  • By understanding their hearing capabilities, scientists can develop more effective strategies to mitigate the effects of noise pollution and protect these vulnerable species.
