The orca or killer whale is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. It is recognizable by its black-and-white patterned body. A cosmopolitan species, orcas can be found in all of the world's oceans in a variety of marine environments, from Arctic and Antarctic regions to tropical seas.
Whales are a widely distributed and diverse group of fully aquatic placental marine mammals. They are an informal grouping within the infraorder Cetacea, which usually excludes dolphins and porpoises. Whales, dolphins and porpoises belong to the order Cetartiodactyla, which consists of even-toed ungulates. Their closest non-cetacean living relatives are the hippopotamuses, from which they and other cetaceans diverged about 54 million years ago. The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have had their last common ancestor around 34 million years ago. Whales consist of eight extant families: Balaenopteridae, Balaenidae, Cetotheriidae, Eschrichtiidae, Monodontidae, Physeteridae, Kogiidae, and Ziphiidae.
Marine mammals are aquatic mammals that rely on the ocean and other marine ecosystems for their existence. They include animals such as seals, whales, manatees, sea otters and polar bears. They are an informal group, unified only by their reliance on marine environments for feeding and survival.
The oceanic whitetip shark, also known as Brown Milbert's sand bar shark, brown shark, lesser white shark, nigano shark, oceanic white-tipped whaler, and silvertip shark, is a large pelagic requiem shark inhabiting tropical and warm temperate seas. Its stocky body is most notable for its long, white-tipped, rounded fins.
The sperm whale or cachalot is the largest of the toothed whales and the largest toothed predator. It is the only living member of the genus Physeter and one of three extant species in the sperm whale family, along with the pygmy sperm whale and dwarf sperm whale of the genus Kogia.
New Island is one of the Falkland Islands, lying north of Beaver Island. It is 238 km (148 mi) from Stanley and is 13 km (8.1 mi) long with an average width of 750 m (820 yd). The highest point is 226 metres (741 ft). The northern and eastern coasts have high cliffs but the eastern coasts are lower lying, with rocky shores and sandy bays. There are several smaller offshore islands in the group; North Island and Saddle Island have high cliffs but Ship Island and Cliff Knob Island are lower lying.
Japanese whaling, in terms of active hunting of whales, is estimated by the Japan Whaling Association to have begun around the 12th century. However, Japanese whaling on an industrial scale began around the 1890s when Japan started to participate in the modern whaling industry, at that time an industry in which many countries participated. Modern Japanese whaling activities have extended far outside Japanese territorial waters, including whale sanctuaries protected by other countries.
The Greenland Sea is a body of water that borders Greenland to the west, the Svalbard archipelago to the east, Fram Strait and the Arctic Ocean to the north, and the Norwegian Sea and Iceland to the south. The Greenland Sea is often defined as part of the Arctic Ocean, sometimes as part of the Atlantic Ocean. However, definitions of the Arctic Ocean and its seas tend to be imprecise or arbitrary. In general usage the term "Arctic Ocean" would exclude the Greenland Sea. In oceanographic studies the Greenland Sea is considered part of the Nordic Seas, along with the Norwegian Sea. The Nordic Seas are the main connection between the Arctic and Atlantic oceans and, as such, could be of great significance in a possible shutdown of thermohaline circulation. In oceanography the Arctic Ocean and Nordic Seas are often referred to collectively as the "Arctic Mediterranean Sea", a marginal sea of the Atlantic.
King George Sound is the name of a sound on the south coast of Western Australia. Originally named King George the Third's Sound, it was referred to as King George's Sound from 1805. The name "King George Sound" gradually came into use from about 1934, prompted by new Admiralty charts supporting the intention to eliminate the possessive 's' from geographical names.
The New Bedford Whaling Museum is a museum in New Bedford, Massachusetts, United States that focuses on the history, science, art, and culture of the international whaling industry, and the "Old Dartmouth" region in the South Coast of Massachusetts. The museum is governed by the Old Dartmouth Historical Society (ODHS), which was established in 1903 "to create and foster an interest in the history of Old Dartmouth." Since then, the museum has expanded its scope to include programming that addresses global issues "including the consequences of natural resource exhaustion, the diversification of industry, and tolerance in a multicultural society." Its collections include over 750,000 items, including 3,000 pieces of scrimshaw and 2,500 logbooks from whaling ships, both of which are the largest collections in the world, as well as five complete whale skeletons. The museum's complex consists of several contiguous buildings housing 20 exhibit galleries and occupying an entire city block within the New Bedford Whaling National Historical Park, although operated independently.
Whaling in Australian waters began in 1791 when five of the 11 ships in the Third Fleet landed their passengers and freight at Sydney Cove and then left Port Jackson to engage in whaling and seal hunting off the coast of Australia and New Zealand. The two main species hunted by such vessels in the early years were right and sperm whales. Humpback, bowhead and other whale species would later be taken.
Penzhina Bay is a long and narrow bay off the northwestern coast of Kamchatka, Russia.
Marine conservation activism is the efforts of non-governmental organizations and individuals to bring about social and political change in the area of marine conservation. Marine conservation is properly conceived as a set of management strategies for the protection and preservation of ecosystems in oceans and seas. Activists raise public awareness and support for conservation, while pushing governments and corporations to practice sound ocean management, create conservation policy, and enforce existing laws and policy through effective regulation. There are many different kinds of organizations and agencies that work toward these common goals. They all are a part of the growing movement that is ocean conservation. These organizations fight for many causes including stopping pollution, overfishing, whaling and by-catching, and supporting marine protected areas.

The MY Steve Irwin was the 59-metre (194 ft) flagship of the Sea Shepherd Conservation Society, and was used in their direct action campaigns against whaling and against illegal fisheries activities. The vessel was built in 1975 and formerly served as a Scottish Fisheries Protection Agency conservation enforcement patrol boat, the FPV Westra, for 28 years.
Oceans is an eight-part documentary series on BBC Two, which seeks to provide a better understanding of the state of the Earth's oceans today, their role in the past, present and future and their significance in global terms. Paul Rose also documents some of the scientific observations his team made as a feature for BBC News.
The bowhead whale is a species of baleen whale belonging to the family Balaenidae and the only living representative of the genus Balaena. They are the only baleen whale endemic to the Arctic and subarctic waters, and are named after their characteristic massive triangular skull, which they use to break through Arctic ice. Other common names of the species are the Greenland right whale or Arctic whale. American whalemen called them the steeple-top, polar whale, or Russia or Russian whale.
The Sea Shepherd Conservation Society engages in various demonstrations, campaigns, and tactical operations at sea and elsewhere, including conventional protests and direct actions to protect marine wildlife. Sea Shepherd operations have included interdiction against commercial fishing, shark poaching and finning, seal hunting and whaling. Many of their activities have been called piracy or terrorism by their targets and by the ICRW. Sea Shepherd says that they have taken more than 4,000 volunteers on operations over a period of 30 years.
The Undersea Adventures of Captain Nemo is a Canadian animated television series of five-minute cartoons produced in 1975 by Rainbow Animation in Toronto, Ontario. The series follows the underwater adventures of Captain Mark Nemo and his two young assistants, Christine and Robbie, in their nuclear-powered submarine, the Nautilus.
A drift whale is a cetacean mammal that has died at sea and floated into shore. This is in contrast to a beached or stranded whale, which reaches land alive and may die there or regain safety in the ocean. Most cetaceans that die, from natural causes or predators, do not wind up on land; most die far offshore and sink deep to become novel ecological zones known as whale fall. Some species that wash ashore are scientifically dolphins, i.e. members of the family Delphinidae, but for ease of use, this article treats them all as "drift whales". For example, one species notorious for mass strandings is the pilot whale, also known as "blackfish", which is taxonomically a dolphin.
