A dolphin is an aquatic mammal in the clade Odontoceti. Dolphins belong to the families Delphinidae, Platanistidae, Iniidae, Pontoporiidae, and possibly extinct Lipotidae. There are 40 extant species named as dolphins.
The orca, or killer whale, is a toothed whale that is the largest member of the oceanic dolphin family. It is the only extant species in the genus Orcinus. Orcas are recognizable by their black-and-white patterned body. A cosmopolitan species, they are found in diverse marine environments, from Arctic to Antarctic regions to tropical seas.
The toothed whales are a parvorder of cetaceans that includes dolphins, porpoises, and all other whales possessing teeth, such as the beaked whales and the sperm whales. 73 species of toothed whales are described. They are one of two living groups of cetaceans, the other being the baleen whales (Mysticeti), which have baleen instead of teeth. The two groups are thought to have diverged around 34 million years ago (mya).

Natsilane is the human hero of the "Blackfish" creation myth, one of the Tlingit and Haida stories about how the various supernatural animal species from the Tlingit culture of the American Northwest coast were created. These stories follow an almost dreamtime-like description of humans and other animal species living completely harmoniously. The animals are depicted as demi-gods, and are always referred to as proper singular nouns. There are other similar stories including how Raccoon got the rings on his tail and why Puma hides in the forest so much.
Dolphin drive hunting, also called dolphin drive fishing, is a method of hunting dolphins and occasionally other small cetaceans by driving them together with boats, usually into a bay or onto a beach. Their escape is prevented by closing off the route to the open sea or ocean with boats and nets. Dolphins are hunted this way in several places around the world including the Solomon Islands, the Faroe Islands, Peru, and Japan, which is the most well-known practitioner of the method. In large numbers dolphins are mostly hunted for their meat; some end up in dolphinariums.
Orcas are large, powerful aquatic apex predators. There have been incidents where orcas were perceived to attack humans in the wild, but such attacks are less common than those by captive orcas. In captivity, there have been several non-fatal and four fatal attacks on humans since the 1970s. Experts are divided as to whether the injuries and deaths were accidental or deliberate attempts to cause harm.

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.
Dawn Therese Brancheau was an American animal trainer at SeaWorld. She worked with orcas at SeaWorld Orlando for fifteen years, including a leading role in revamping the Shamu show, and was SeaWorld's poster girl.

Tilikum, nicknamed Tilly, was a captive male orca who spent most of his life at SeaWorld Orlando in Florida. He was captured in Iceland in 1983; about a year later, he was transferred to Sealand of the Pacific near Victoria, British Columbia, Canada. He was subsequently transferred in 1992 to SeaWorld in Orlando, Florida, where he sired 21 calves throughout his life.
A bait ball, or baitball, occurs when small fish swarm in a tightly packed spherical formation about a common centre. It is a last-ditch defensive measure adopted by small schooling fish when they are threatened by predators. Small schooling fish are eaten by many types of predators, and for this reason they are called bait fish or forage fish.
