Norway stopped hunting the whale in 1973 but northern bottlenose whales are still killed in the Faroe Islands. |
|
Faroese regulations only allow the killing of bottlenose whales which have beached themselves and cannot be driven out again. |
|
This light grey patch found on the throat of pilot whales forms the shape of an anchor. |
|
Pilot whales mainly feed on cephalopods, though in certain regions fish may be more prominent in their diet. |
|
During a specific time of year, approximately December to March, these whales beach themselves in high numbers along the coast of New Zealand. |
|
The whistles and pulsed calls that pilot whales make seem not to fall into distinct types, but rather can be arranged on a continuum. |
|
The hunters first surround the pilot whales with a wide semicircle of many boats. |
|
The boats then drive the pilot whales into a bay or to the bottom of a fjord. |
|
The catches increased every year until in 1956, there were approximately 10,000 pilot whales successfully captured and killed. |
|
Aside from the Faroe Islands, a few pilot whales are taken opportunistically in Greenland each year. |
|
In these places, pilot whales provide valuable income for people living in rural fishing communities. |
|
Killer whales have a diverse diet, although individual populations often specialize in particular types of prey. |
|
Killer whales are apex predators, as there is no animal that preys on them. |
|
Basque whalers would have given it such name after observing pods of orcas hunting baleen whales. |
|
Other populations have not been as well studied, although specialized fish and mammal eating killer whales have been distinguished elsewhere. |
|
Of three orca ecotypes in the Antarctic, one preys on minke whales, the second on seals and penguins and the third on fish. |
|
Killer whales have good eyesight above and below the water, excellent hearing, and a good sense of touch. |
