Humans aren't the only creatures who are constantly talking and transmitting messages: animals find all sorts of ways to keep in touch without saying a word. They use colors, patterns, smells, movements, vibrations, sounds, and even electricity to help them identify their own family or “team” — not to mention find food and shelter, defend their territory, woo the proper mate, and care for their young. From the chatter of dolphins to the click of a moth, from the stripes of a reef fish to the rumbling of elephants, this funny, fascinating book unlocks the mysteries of how animals talk and squawk to one another— and how humans try to talk back. Back matter includes an index and a glossary.
