Whales' foraging strategies revealed by new technology
Marine biologists are beginning to understand the varied diving and foraging strategies of filter-feeding whales by analyzing data from multisensor tags attached to the animals with suction cups. Such tags, in combination with other techniques such as echolocation, are providing a wealth of fine detail about how the world's largest creatures find and trap their prey.
Recent studies on the behavior of baleen whales—which filter small fish or invertebrate animals from seawater—are described in the February issue of BioScience. Jeremy A. Goldbogen of the Cascadia Research ...
