Cetacea is an infraorder of aquatic mammals that includes whales, dolphins, and porpoises. Key characteristics are their fully aquatic lifestyle, streamlined body shape, often large size and exclusively carnivorous diet. They propel themselves through the water with powerful up-and-down movement of their tail which ends in a paddle-like fluke, using their flipper-shaped forelimbs to maneuver.
A dolphin is an aquatic mammal within the infraorder Cetacea. Dolphin species belong to the families Delphinidae, Platanistidae, Iniidae, Pontoporiidae, and the extinct Lipotidae. There are 40 extant species named as dolphins.
A wholphin is an extremely rare cetacean hybrid born from a mating of a female common bottlenose dolphin with a male false killer whale. The name implies a hybrid of whale and dolphin, although taxonomically, both are within the oceanic dolphin family, which is within the toothed whale parvorder. Wholphins have been born in captivity and have also been reported in the wild.
Bottlenose dolphins are aquatic mammals in the genus Tursiops. They are common, cosmopolitan members of the family Delphinidae, the family of oceanic dolphins. Molecular studies show the genus definitively contains two species: the common bottlenose dolphin and the Indo-Pacific bottlenose dolphin. Others, like the Burrunan dolphin, may be alternately considered their own species or be subspecies of T. aduncus. Bottlenose dolphins inhabit warm and temperate seas worldwide, being found everywhere except for the Arctic and Antarctic Circle regions. Their name derives from the Latin tursio (dolphin) and truncatus for their characteristic truncated teeth.
Oceanic dolphins or Delphinidae are a widely distributed family of dolphins that live in the sea. Close to forty extant species are recognised. They include several big species whose common names contain "whale" rather than "dolphin", such as the Globicephalinae. Delphinidae is a family within the superfamily Delphinoidea, which also includes the porpoises (Phocoenidae) and the Monodontidae. River dolphins are relatives of the Delphinoidea.
The toothed whales are a parvorder of cetaceans that includes dolphins, porpoises, and all other whales possessing teeth, such as the beaked whales and sperm whales. Seventy-three 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).
Cetacean intelligence is the cognitive ability of the infraorder Cetacea of mammals. This order includes whales, porpoises, and dolphins.
SeaWorld is an American theme park chain with headquarters in Orlando, Florida. It is a proprietor of marine mammal parks, oceanariums, animal theme parks, and rehabilitation centers owned by SeaWorld Parks & Entertainment. The parks feature orcas, sea lion, and dolphin shows and zoological displays featuring various other marine animals.
The Indo-Pacific bottlenose dolphin is a species of bottlenose dolphin. This dolphin grows to 2.6 m (8.5 ft) long, and weighs up to 230 kg (510 lb). It lives in the waters around India, northern Australia, South China, the Red Sea, and the eastern coast of Africa. Its back is dark grey and its belly is lighter grey or nearly white with grey spots.
The melon-headed whale, also known less commonly as the electra dolphin, little killer whale, or many-toothed blackfish, is a toothed whale of the oceanic dolphin family (Delphinidae). The common name is derived from the head shape. Melon-headed whales are widely distributed throughout deep tropical and subtropical waters worldwide, but they are rarely encountered at sea. They are found near shore mostly around oceanic islands, such as Hawaii, French Polynesia, and the Philippines.
The common bottlenose dolphin or Atlantic bottlenose dolphin is a wide-ranging marine mammal of the family Delphinidae. The common bottlenose dolphin is a very familiar dolphin due to the wide exposure it gets in captivity in marine parks and dolphinariums, and in movies and television programs. It is the largest species of the beaked dolphins. It inhabits temperate and tropical oceans throughout the world, and is absent only from polar waters. While formerly known simply as the bottlenose dolphin, this term is now applied to the genus Tursiops as a whole. As considerable genetic variation has been described within this species, even between neighboring populations, many experts think additional species may be recognized.
A dolphinarium is an aquarium for dolphins. The dolphins are usually kept in a pool, though occasionally they may be kept in pens in the open sea, either for research or public performances. Some dolphinariums consist of one pool where dolphins perform for the public, others are part of larger parks, such as marine mammal parks, zoos or theme parks, with other animals and attractions as well.
Louis Herman was an American marine biologist. He was a researcher of dolphin sensory abilities, dolphin cognition, and humpback whales. He was professor in the Department of Psychology and a cooperating faculty member of the Department of Oceanography at the University of Hawaiʻi at Mānoa. He founded the Kewalo Basin Marine Mammal Laboratory (KBMML) in Honolulu, Hawaii in 1970 to study bottlenose dolphin perception, cognition, and communication. In 1975, he pioneered the scientific study of the annual winter migration of humpback whales into Hawaiian waters. Together with Adam Pack, he founded The Dolphin Institute in 1993, a non-profit corporation dedicated to dolphins and whales through education, research, and conservation.
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 and then 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, the most well-known practitioner of this method. By numbers, dolphins are mostly hunted for their meat; some end up in dolphinariums.
The Tethys Research Institute is a non-profit research organisation founded in 1986 to support marine conservation through science and public awareness. The institute has its headquarters at the Civic Aquarium of Milan, Italy. Tethys' activities are mainly carried out in the Mediterranean Sea, although research programmes have been conducted also in the Black Sea, the North Atlantic Ocean, the Caribbean as well as in the Red Sea and Antarctica. The results of these activities have been presented in scientific publications as well as in meetings, workshops and conferences.
Earthtrust (ET) is a non-governmental environmental organization based on the island of Oahu in Hawaii. Earthtrust was founded by in 1976 by Don White, a founding member and former international campaign director of Greenpeace International who has directed the organization since its inception. Focusing mostly on marine conservation, Earthtrust is responsible for the largest conservation victory in history by biomass due to its critical role in exposing, documenting, and ending large-scale high seas driftnetting. Earthtrust has been involved in many high-profile advocacy actions; notably the pioneering use of genetic analysis to demonstrate the prevalence of pirate whaling, the first scientific demonstration of self-awareness in a non-primate at its Delphis lab, creation of the first international seafood environmental accreditation standard, binding the world's largest tuna firm (StarKist) contractually to its tuna-acquisition criteria, and being the first to take charge of the environmental disaster left by the retreating Iraqi army in the Gulf War. The organization was designed to have a high funding efficiency and effectiveness, showcasing the methodologies of "effectivism" and "system steering" as alternatives to standard activism, by preferentially taking on what would otherwise be considered "impossible missions".
Dawn Therese Brancheau was an American senior 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. She was killed by an orca, Tilikum. Tilikum was also involved in the deaths of two other people: Keltie Byrne and Daniel P. Dukes.
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 in Victoria, British Columbia. He was subsequently transferred in 1992 to SeaWorld in Orlando, Florida, where he sired 21 calves throughout his life.
The Taiji dolphin drive hunt is based on driving dolphins and other small cetaceans into a small bay where they can be killed or captured for their meat and for sale to dolphinariums. The new primary killing method is done by cutting the spinal cord of the dolphin, a method that claims to decrease the mammal's time to death. Taiji has a long connection to whaling in Japan. The 2009 documentary film The Cove drew international attention to the hunt. Taiji is the only town in Japan where drive hunting still takes place on a large scale.
Diana Reiss is a professor of psychology at Hunter College and in the graduate program of Animal Behavior and Comparative Psychology at the City University of New York. Reiss's research has focused on understanding cognition and communication in dolphins and other cetaceans. Her important contributions include demonstrating mirror self-awareness in dolphins via the Mirror test.
