Now, some of them have figured out, it means dinner. Scientists recently figured out that sperm whales in the Gulf of Alaska zero in on boat engines to locate miles of fishing lines hung with valuable sablefish. The work has led researchers to recommend some low-cost ways for fishermen to hoodwink the highly intelligent cetaceans. The whales leave behind partially chewed bodies, dismembered lips or nothing at all on the hooks. Sablefish gaining popularity The sweet, flaky flesh of the sablefish, long prized in Japan and Hawaii, is gaining popularity in the mainland United States, where it is listed on menus as butterfish or black cod.

Blue whales are thought to be among the most endangered of the great whales. Scientists estimate that the whaling industry destroyed 97 percent of the world's population. Over , blue whales were killed in the Antarctic alone. The largest remnant group of blue whales in the world may feed off the California coast during the summer. The whales in this population migrate between feeding areas along the west coast of the United States and Canada and breeding and calving grounds off Mexico and Central America. The exact locations of the breeding and calving grounds remain unknown.

One of the founding principles of Pacific Whale Foundation is to contribute to the scientific understanding of marine life and marine ecosystems. Our research program uses a two-pronged approach of long-term and short-term projects. Short-term studies are based on specific questions and issues in contemporary research. They contribute to the peer-reviewed body of knowledge that is disseminated primarily via scientific journals, reports, and meetings of the scientific community and resource management agencies. Long-term projects generally involve collection of data over many years, producing results at a lower rate but providing the background information for short-term efforts.
Sperm whales are the largest of the toothed whales and have one of the widest global distributions of any marine mammal species. They are found in all deep oceans, from the equator to the edge of the pack ice in the Arctic and Antarctic. They are named after the waxy substance, spermaceti, found in their heads.
