At the All rights reserved extreme of maximum body size observed among mammals, baleen whales exhibit a unique combination of high overall energetic demands and low mass-specific metabolic rates. As a result, most baleen whale species have evolved filter-feeding mechanisms and foraging strategies that take advan- tage of seasonally abundant yet patchily and ephemerally distributed prey re- sources.
