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.
