Recent research has revealed that minke whales can detect high-frequency sounds up to 90 kilohertz (kHz), a significant finding that enhances our understanding of these marine mammals.  

• The study reveals minke whales are more affected by ocean noise pollution than previously thought, with shipping, naval sonar, and industrial activities increasing marine noise levels. 
  • Anthropogenic noise can interfere with marine mammals' communication, foraging behaviour, and navigation abilities. 
  • Current regulations may insufficiently protect baleen whales, as their hearing ranges were previously underestimated. This new data calls for a reevaluation of marine noise pollution policies. 
• Minke Whales: Minke Whales (Balaenoptera acutorostrata) are the smallest member of the rorqual whale family, which includes other baleen whales. It can reach a maximum length of about 10.7 meters. 
• Conservation status: 
  • Common minke whale:  
    • IUCN: Least concern 
    • CMS: Appendix II 
    • CITES: Appendix I (threatened with extinction) 
  • Antarctic minke whale:  
    • IUCN: Data Deficient  
    • CMS: Appendix II
