I just finished a wonderful book that readers of this comment thread may find interesting: "An Immense World: How Animal Senses Reveal the Hidden Realms Around Us" by Ed Yong. The book is a relatively non-technical deep dive into the many ways different organisms sense their environments. The chapters are organized by the senses; in the chapter on hearing, he covers everything from mammals to insects. His discussion of echolocation was amazing: of the many species of bats, there are a number of quite different ways in which they use echolocation. Some bats use quite different chirps for "scan mode" versus "final approach on target" mode. He gives plots of FFT's of the various sounds researchers have captured. I could go on and on about his amazing descriptions of insect vibration sensing, electric eels, taste, sight in its various forms across species, etc. Great read, highly recommended.
