Overview: How does a church service sound to a bat? What does your cat really hear? Enter unfamiliar sound worlds to discover elephant conversations pitched below our hearing, birds that navigate using distant sound guides and whales that call across oceans. Find owls that hunt using sound maps, fish as noisy as birds, and rats that can hear a rattlesnake strike. Bats and dolphins create images in sound, and there is even a shrimp that uses sound as a lethal weapon.
