Blue Whales

Blue whales are the largest animals ever to have lived on earth. Their populations once numbered hunderds of thousands before being decimated worldwide by relentless commercial whaling. The impressive sight of a 100 ft long, 160 ton giant racing through the sea was one many thought might never be seen again. Still considered an endangered species, this elusive giant of the seas appears to be making a strong recovery in some areas. This book examines the latest discoveries about these enormous animals. The authors draw from their pioneering work, describing how their research is conducted and what is being learned about blue whale populations, behaviour and their conservation.
