Jonathan Gordon has written a splendid book describing the sperm whale’s habitat and lifestyle. These huge creatures of the deep often leave their calves frolicking at the surface of the ocean to dive hundreds of feet into the deep sea in their search for food. These crushing depths might prove fatal to other sea creatures, but the sperm whale has adapted its rib cage to collapse under pressure. The sperm whale’s pattern of clicks or codas are distinctive forms of communication, usually heard when the whales are socializing near the surface. Variations also occur in whales located near the Galapagos, Azores or Caribbean. Fishing trawlers pose a great risk for the sperm whales, as the whales become easily entangled in the large nets and drown. Seismic surveys, military sonar and underwater experiments also wreak havoc with the sperm whale’s need for sonar. This type of acoustic noise is of great concern, since the whale’s eye is very small compared to its body length. Its main sensory source is sound. Illustrated with stunning photographs, this book is suitable as a gift or as a worthy read resting on your coffee table.Was this review helpful? Yes NoThank you for your feedback.
