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. 

How does time appear to a bird, a shrew or even an elephant?
Enter unfamiliar time-worlds where flies outwit humans in slow motion, birds slice through time to catch their prey and plants reveal strange movements. Discover how animals time their seasonal lives and how the moon influences mayfly swarming and the mass stranding of grunion fish. In this world, natural clocks control the opening of flowers, the activity of bees, the navigation of birds, and even an animal that invades the world once every 17 years.
