"This revised fifth edition includes Hoyt's original account of his trips to the waters off Vancouver Island in the 1970s to help make a documentary about the killer whale, about which little was known then. Exciting new chapters bring readers up-to-date on the revolution in public awareness and killer whale research that has taken place since. Now a world-renowned expert on whales and dolphins, Hoyt shares orca wisdom gleaned from decades of additional field study in the Russian Far East as well as return trips to Canada's West Coast to visit with the descendants of the killer whales the author encountered 45 years ago."--
