Beaked whales have been shrouded in mystery for most of the
twentieth century. Denizens of deep, remote ocean waters and highly
resistant to life in captivity, they have proven notoriously
difficult for humans to observe. Over the past few decades,
however, scientists have gained a better understanding of this
distinct group of cetaceans, deciphering the natural history of the
twenty-two beaked whale species. Here, famed artist and naturalist
Richard Ellis and leading beaked whale researcher James G. Mead
bring these elusive marine mammals into the limelight. Beaked
whales' generous life spans can extend well past 70 years. They
spend their decades diving to extreme depths in search of prey,
which they capture by expanding their oral cavity suddenly to suck
in the squid or fish they are hunting. It appears that these sleek
predators may engage in fierce, clandestine aquatic battles, as the
bodies of many males are covered in scars. Because many species are
only somewhat larger than dolphins, they are often confused with
porpoises; however, some larger beaked whale species may grow to 40
feet. These enigmatic and compelling creatures need our help; their
numbers are declining, perhaps due to the damaging effects of naval
sonar on their sophisticated auditory systems. In Ellis and Mead's
book, the beaked whales finally get their due. The duo provides a
combination of captivating stories about the species, original
Richard Ellis art, and photos from leading natural history
photographers. The result is an accessible, beautiful book-the
first of its kind on this unusual group of cetaceans. Meet the
beaked whales, and enjoy the fascinating and mysterious world in
which they live.
