Oceanic dolphins are members of the cetacean family Delphinidae. These marine mammals are related to whales and porpoises. They are found worldwide, mostly in the shallower seas of the continental shelves. As the name implies, these dolphins tend to be found in the open seas, unlike the river dolphins, although a few species such as the Irrawaddy dolphin are coastal or riverine.
The killer whale (Orcinus orca), also referred to as the orca whale or orca, and less commonly as the blackfish, is a toothed whale belonging to the oceanic dolphin family. Killer whales are found in all oceans, from the frigid Arctic and Antarctic regions to tropical seas. Killer whales as a species have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as sea lions, seals, walruses, and even large whales. Killer whales are regarded as apex predators, lacking natural predators.
Wildlife rehabilitation is the process of removing from the wild and caring for injured, orphaned, or sick wild animals. The goal of wildlife rehabilitation is to provide the food, housing and medical care of these animals, returning them to the wild after treatment.
Captive orcas (killer whales) are large predatory marine mammals that were first captured live and displayed in exhibitions in the 1960s, and soon became popular attractions at public aquariums and aquatic theme parks due to their intelligence, trainability, striking appearance, playfulness in captivity, and sheer size. However, the captive environment usually bears little resemblance to their wild habitat, and the social groups that the killer whales are put into are foreign to those found in the wild. As of 13 August 2013, there are 45 orcas are in captivity worldwide, 32 of which are captive-born. The practice of keeping killer whales in captivity is controversial.
The North Pacific right whale (Eubalaena japonica) is a very large, robust baleen whale species that is now extremely rare and endangered. The Northeast Pacific subpopulation, which summers in the southeastern Bering Sea and Gulf of Alaska, may have no more than 50 animals. A western subpopulation that summers in the Sea of Okhotsk between the Kuril Islands and Sakhalin Island appears to number in the low hundreds of animals. Prior to commercial whaling in the North Pacific (i.e. pre-1835) the populations in the North Pacific probably were over 20,000 animals. The taking of right whales in commercial whaling has been prohibited by one or more international treaties since 1935. However, between 1962 and 1968, illegal Soviet whaling killed 529 right whales in the Bering Sea and Gulf of Alaska as well as 132 right whales in the Sea Okhotsk.
The International Union for the Conservation of Nature categorizes the species as "Endangered". However, it categorizes the Northeast Pacific subpopulation as "Critically Endangered". According to the Center for Biological Diversity, the North Pacific right whale is the most endangered whale on Earth.
