💁🏻‍♀️ TIL: 🐘🦻 #Elephants can hear messages sent through ground vibrations from more than 10 km away using bone conduction. A #study found that elephants’ larger middle ear bones transmit low-frequency vibrations to the cochlea more effectively than human #ears. A special #muscle may also let elephants voluntarily close their ear canals, potentially boosting sensitivity to infrasonic #sounds by up to 30 times. 👉 https://www.zmescience.com/science/news-science/elephants-may-hear-messages-through-ground-vibrations-from-more-than-10-kilometers-away/ #hearing #infrasound #animals #communication #anatomy #science #biology #zoology #wildlife #harvard

Elephants May Hear Messages Through Ground Vibrations From More Than 10 Kilometers Away

Elephants may hear messages traveling through the ground from more than 10 kilometers away, thanks to massive ear bones and a muscle that can shut their ear canals.

"While we know that seals can hear [in both air and water] what’s long remained a mystery is exactly how they do so, and when this ability evolved. In our new paper, published today in Proceedings of the Royal Society B: Biological Sciences, we investigated amphibious hearing in seals to find answers to these questions." https://theconversation.com/seals-have-a-unique-superpower-in-their-ears-and-we-finally-know-how-it-evolved-287072 #Seals #Hearing #Biology

Seals have a unique superpower in their ears, and we finally know how it evolved

Unlike all other mammals, seals can hear both in the air and underwater. How do they do this?
