Listen as Magnus tells us about his interesting work on the bioacoustics of marine animals. With many exciting examples, he explains his focus on how animals hear. He explains how captive animals help us test techniques before running field testing on wild animals.

“Would you rather be deaf or blind?” asks Magnus as he explains with relatable analogies. When vision underwater is limited, one has to rely on hearing. He shares how water is a good conductor of...
