内容説明
This book focuses on transient killer whales. Enigmatic and elusive,these mammal-hunting whales are difficult animals to study. They travelin small groups, often moving unpredictably, which makes them lessconspicuous than the larger resident pods. For these and other reasons,our understanding of the life history and ecology of transient killerwhales has lagged behind that of residents. Transients contains thelatest information on the natural history of transient killer whales,including their feeding habits, social lives, and distributionpatterns. The catalogue section contains photographs of and notes onover 200 individual whales. Numerous sidebars contain interestingobservations on encounters with transients as well as information onhow and where to best watch them.
