Killer Whales: The Natural History and Genealogy of Orcinus Orca in British Columbia and Washington State (Updated Edition)
by John K. B. Ford, Graeme M. Ellis, Kenneth C. Balcomb
Category: Killer whale

The three authors have been studying killer whales since the 1970s, when they began photographing dorsal fins and the gray saddle patches at the base of the fins in order to identify individual whales. They present the latest information on killer whale natural history; suggestions on how, when, and where to best watch killer whales; and a catalog of some 300 photographs of "resident" killer whales which can be used to identify individuals and their family groups. 10.75x9" Annotation copyright by Book News, Inc., Portland, OR
