The orca, or killer whale, is a toothed whale and the largest member of the oceanic dolphin family. It is the only extant species in the genus Orcinus and is recognizable by its black-and-white patterned body. A cosmopolitan species, they are found in diverse marine environments, from Arctic to Antarctic regions to tropical seas.
Puget Sound is a complex estuarine system of interconnected marine waterways and basins located on the northwest coast of the U.S. state of Washington. As a part of the Salish Sea, the sound has one major and two minor connections to the Strait of Juan de Fuca, which in turn connects to the open Pacific Ocean. The major connection is Admiralty Inlet; the minor connections are Deception Pass and the Swinomish Channel.
The Chinook salmon is the largest and most valuable species of Pacific salmon. Its common name is derived from the Chinookan peoples. Other vernacular names for the species include king salmon, Quinnat salmon, Tsumen, spring salmon, chrome hog, Blackmouth, and Tyee salmon. The scientific species name is based on the Russian common name chavycha (чавыча).
The National Marine Fisheries Service (NMFS), informally known as NOAA Fisheries, is a United States federal agency within the U.S. Department of Commerce's National Oceanic and Atmospheric Administration (NOAA) that is responsible for the stewardship of U.S. national marine resources. It conserves and manages fisheries to promote sustainability and prevent lost economic potential associated with overfishing, declining species, and degraded habitats.
Puget Sound salmon recovery is a collective effort of federal, state and local authorities and non-profit coalitions of universities, scientists, business and industry aimed at restoring Pacific salmon and anadromous forms of Pacific trout (Oncorhynchus) within the Puget Sound region. The Puget Sound lies within the native range of the Pacific Salmon (Oncorhynchus) and two sea-run forms of Pacific trout, the coastal rainbow trout or steelhead and coastal cutthroat trout. Populations of Oncorhynchus have seen significant declines since the middle of the 19th century due to over fishing, habitat loss, pollution and disease. Salmon species residing in or migrating through the Puget Sound to spawning streams include Chum, Coho, Chinook, Sockeye, and Pink salmon. Pacific salmon require freshwater rivers for spawning and most major tributaries of the Puget Sound have salmon, steelhead and cutthroat trout spawning runs.
Lolita, also called Tokitae or Toki for short,, was a captive female orca of the southern resident population captured from the wild in September 1970 and displayed at the Miami Seaquarium in Florida. She was retired from performing and taken off public display in 2022, and subsequently died in August 2023. At the time of her death, Lolita was the second-oldest orca in captivity after Corky at SeaWorld San Diego.
The Miami Seaquarium is a 38-acre (15 ha) oceanarium located on the island of Virginia Key in Biscayne Bay, Miami-Dade County, Florida located near downtown Miami.
The Salish Sea is a marginal sea of the Pacific Ocean located in the Canadian province of British Columbia and the U.S. state of Washington. It includes the Strait of Georgia, the Strait of Juan de Fuca, Puget Sound, and an intricate network of connecting channels and adjoining waterways.
L98 Luna also known as Tsux'iit, was an orca born in Puget Sound. After being separated from his mother, Splash (1985–2008) while still young, Luna spent five years in Nootka Sound, an ocean inlet of western Vancouver Island, where he had extensive human contact and became recognized internationally.
Springer, officially named A73, is a wild orca from the Northern Resident Community of orcas, which frequents the waters off the northern part of Vancouver Island every summer. In January 2002, Springer, then a calf developmentally equivalent to a human toddler, was discovered alone and emaciated some 250 miles from the territory of her family. Experts identified Springer by her vocal calls that are specific to her family, or "pod," and by examining photographs of her eye patch. They were also able to determine where Springer's pod was currently located.
The environmental issues on Maury Island are linked to broader Puget Sound environmental issues, which include concerns regarding declining salmon and forage fish populations, degrading critical marine and shoreline habitats, and threatened species such as the Orca.
Dozens of orcas are held in captivity for breeding or performance purposes. The practice of capturing and displaying orcas in exhibitions began in the 1960s, and they soon became popular attractions at public aquariums and aquatic theme parks due to their intelligence, trainability, striking appearance, playfulness, and sheer size. As of 24 March 2024, around 55 orcas are in captivity worldwide, 33 of which were captive-born. At that time, there were 18 orcas in the SeaWorld parks.
The southern resident orcas, also known as the southern resident killer whales (SRKW), are the smallest of four communities of the exclusively fish-eating ecotype of orca in the northeast Pacific Ocean. The southern resident orcas form a closed society with no emigration or dispersal of individuals, and no gene flow with other orca populations. The fish-eating ecotype was historically given the name 'resident,' but other ecotypes named 'transient' and 'offshore' are also resident in the same area.
Edward Irving "Ted" Griffin is an American former aquarium owner and entrepreneur who was the first man to ever swim with a killer whale in a public exhibition, with the whale named Namu. He is best known for capturing, performing with, and selling a number of orcas during the late 1960s and early 1970s.
Whale feces, the excrement of whales, has a vital role in the ecology of oceans, earning whales the title of "marine ecosystem engineers." This significant ecological role stems from the nutrients and compounds found in whale feces, which have far-reaching effects on marine life.
Tahlequah, also known as J35, is an orca of the southern resident community in the northeastern Pacific Ocean. She has given birth to three known offspring, a male (Notch) in 2010, a female (Tali) in 2018, and another male (Phoenix) in 2020. Her second calf, Tali, died shortly after birth and J35 carried her body for 17 days in an apparent show of grief that attracted international attention.
Lance Barrett-Lennard is a Canadian biologist specializing in the behavioural ecology and population biology of killer whales. A molecular geneticist, Barrett-Lennard uses DNA analysis to study the dispersal, mating habits, and group structure of killer whale sub-populations in the Pacific Northwest. He is best known for his research concerning the conservation of the Southern Resident killer whale sub-population. As of 2022, he is a Senior Scientist in the Cetacean Conservation Research Program at the Raincoast Conservation Foundation.
The Yukon Harbor orca capture operation was the first planned, deliberate trapping of a large group of orcas. 15 southern resident orcas were trapped by Ted Griffin and his Seattle Public Aquarium party on 15 February 1967, in Yukon Harbor on the west side of Puget Sound. The first four orcas that had been taken into captivity had been captured singly, and mostly opportunistically. Those four were named Wanda, Moby Doll, Namu, and Shamu—who was then the only surviving one. Through them, interest in orcas had escalated.
The waters of the Salish Sea, on the west coast of North America, are home to several ecologically distinct populations of orcas. The area supports three major ecotypes of orcas: northern residents, southern residents, and transients. A fourth ecotype, the offshore orcas, occasionally venture into nearshore waters. Little to no interaction occurs between the different ecotypes. Resident and transient orcas have not been observed interbreeding, although occasional brief interactions occur.
The marine mammals of the Salish Sea are numerous and diverse, both in taxonomy and morphology. A total of six species of pinnipeds, eight species of baleen whales, seventeen species of toothed whales, and one mustelid inhabiting the local waters of the Salish Sea and the outer coastal waters over the continental shelf off Washington and British Columbia. The Salish Sea's ecosystem is characterized by cold, upwelling-drenched waters that provide nourishment for huge quantities of fish and crustaceans, the primary food of marine mammals, and as such, the diversity and abundance of marine mammals in the area are among the highest in the world.
