The elephant's secret sense : the hidden voice of the African elephant.
(Book)

"While observing a family group of elephants in the wild, Caitlin O'Connell, a young field scientist, noticed a peculiar listening behavior. A matriarch she had been watching for months turned her massive head and lifted her foot off the ground. As she scanned the horizon, the other elephants followed suit, all facing the same direction. O'Connell soon made a groundbreaking discovery: the elephants were "listening through limbs," feeling the ripples of the earth's surface for approaching friends and enemies. Through their feet, toenails, trunks, and other, subtler modes of communication, these enormous animals were communicating to one another, demonstrating the vital importance of social relationships in their lives." "An unforgettable journey of scientific discovery, The Elephant's Secret Sense takes you deep into the wilds of Namibia, from the tops of isolated, desert observation towers to the jaws and claws of ravenous lions to aerial expeditions and dusty highways, where the naturalists do their difficult work in a troubled land threatened by expanding human populations and unstable politics. Resonant with the powerful calls of the mysterious elephant, this is a story about the resilience of nature and the inspiring, astonishing, and often heartbreaking places where humans and wild animals come together."--BOOK JACKET
