In this post, we will see the book The Living Sonars Of The Ocean by B. F. Sergeev.

About the book

This book concerns that mysterious world that lies beneath the ocean waves. From antiquity until relatively recently, people have thought it was a silent world, but scientists now realize that marine life is, in fact, quite noisy. Myriads of underwater creatures, such as dolphins, whales, and seals, obtain information in a way quite incomprehensible to us, Homo sapiens, for they use sonar or echolocation. Many terrestrial animals use echolocation to see and hear in conditions in which human beings are deaf and blind. ‘What is echolocation?’ and ‘How do wild animals use it to obtain information?’ are just some of the questions answered in ‘The Living Sonars of the Ocean’ by B. Sergeev.
