The term whale can refer to all cetaceans, to just the larger ones, or only to members of particular families within the order Cetacea. The last definition is the one followed here. Whales are those cetaceans which are neither dolphins (i.e. members of the families Delphinidae or Platanistoidae) nor porpoises. This can lead to some confusion because Orcas (Killer Whales) and Pilot whales have "whale" in their name, but they are dolphins for the purpose of classification.

Some species of large whales are endangered as a result of large-scale whaling during the nineteenth and twentieth centuries. For centuries large whales have been hunted for oil, meat, baleen and ambergris (a perfume ingredient from the intestine of sperm whales). By the middle of the 20th century, whaling left many populations severely depleted.
The International Whaling Commission introduced a six year moratorium on all commercial whaling in 1986, which has been extended to the present day. For various reasons some exceptions to this moratorium exist; current whaling nations are Norway, Iceland and Japan and the aboriginal communities of Siberia, Alaska and northern Canada. For details, see whaling.
Several species of small whales are caught as bycatch in fisheries for other species. In the tuna fishery in the Eastern Tropical Pacific thousands of dolphins were drowned in purse-seine nets, until measures to prevent this were introduced. Fishing gear and deployment modifications, and eco-labelling (dolphin-safe or dolphin-friendly brands of canned tuna), have contributed to a reduction in the mortality of dolphins by tuna fishing vessels in recent years. In many countries, small whales are still hunted for food, oil, meat or bait.

Whaling fleet prevented from killing whales
Following a 10-day search in Antarctic waters, the Greenpeace ship Esperanza confronted Japan’s whaling fleet in the Southern Ocean Whale Sanctuary last week. After a high speed chase over hundreds of miles the factory ship Nisshin Maru was driven out of the hunting grounds. Without this ship, the rest of the fleet has been unable to hunt whales for the last 5 days. The Esperanza continues to follow the Nisshin Maru which is now heading south again.
