There are no words in the language of animals, but there is communication by sound, sight, and smell.  The study of animal communication is a new branch of science, and much of the information discussed here has only recently been discovered.  In the past fifteen years new electronic machines have been developed that make it possible to record animal sounds accurately, and thus analyze them.

How does a mother seal recognize her pup among thousands of others? Why do sea gulls always gather behind a loaded fishing boat? How does one bee indicate to others not only the presence of food, but its exact location? In each case the animal uses a signal, and the endless variety of these signals is presented here in rich detail, starting with the underwater language of fishes, and continuing through communication among reptiles, birds, mammals, and insects.

Dr. William N. Tavolga of the American Museum of Natural History calls this book "a happy combination of accurate reporting, clear writing, and enjoyable reading."
