Deep-sea whales such as Sperm Whales use a nose structure called “phonic lips” to create clicks louder than a rifle shot—making them the loudest animals on Earth, even at depths of 1,000 meters. Scientists discovered that a millisecond burst of air through these vibrating lips produces the powerful sound used for hunting and navigation. -paraphrased from a study done over 10 years by whale biologist Prof Peter Madsen of Aarhus University Denmark- 🎥 @theoceantourist #spermwhales #spermwhale #san
