Ancient Romans originally used orca (pl. [155] They can be trained in captivity and are often described as intelligent,[156][157] although defining and measuring "intelligence" is difficult in a species whose environment and behavioural strategies are very different from those of humans. [172] Mothers usually calve a single offspring about once every five years. [134] One killer whale was also attacked by its companions after being shot. The World Health Organization has set air quality standards in an effort to control the emissions produced by these vessels. [120], Other marine mammal prey species include nearly 20 species of seal, sea lion and fur seal. [34] Although resident killer whales have never been observed to eat other marine mammals, they occasionally harass and kill porpoises and seals for no apparent reason. Killer Whale open mouth Feeding Orca. [179] Blubber samples in the Norwegian Arctic show higher levels of PCBs, pesticides and brominated flame-retardants than in polar bears. [151], Norwegian and Icelandic herring-eating orcas appear to have different vocalizations for activities like hunting. Wild males who survive infancy live 31 years on average, and up to 50–60 years. [91][3][30] Local estimates include roughly 25,000 in the Antarctic, 8,500 in the tropical Pacific, 2,250–2,700 off the cooler northeast Pacific and 500–1,500 off Norway. The few non-fatal attacks by wild orcas are believed to be cases of mistaken identity. Continued. The whale ended up devouring the seal. Try Different Quizzes People Are Talking About! – One in the killer whale’s mouth, the food is not chewed, but instead, it is either immediately swallowed or torn and shredded before swallowing (SeaWorld Parks & Entertainment, n.d.). Air pollutants that bind with exhaust fumes are responsible for the activation of the cytochrome P450 1A gene family. She became the first whale to be successfully reintegrated into a wild pod after human intervention, crystallizing decades of research into the vocal behaviour and social structure of the region's killer whales. [60], An individual killer whale can often be identified from its dorsal fin and saddle patch. [113] The arrival of orcas in an area can cause white sharks to flee and forage elsewhere. All members of a resident pod use similar calls, known collectively as a dialect. Orcas, or killer whales, are the largest of the dolphins and one of the world's most powerful predators. [137], Day-to-day killer whale behaviour generally consists of foraging, travelling, resting and socializing. They are reported as seasonally common in the Canadian Arctic, including Baffin Bay between Greenland and Nunavut, as well as Tasmania and Macquarie Island. [148], Dialects also distinguish types. [153], Killer whales have the second-heaviest brains among marine mammals[154] (after sperm whales, which have the largest brain of any animal). [229] Researchers have successfully identified this gene in skin biopsies of live whales and also the lungs of deceased whales. The orcas appeared on August 1 off Cape Spear and appear to have frightened off the area's humpbacks and minkes. [222] Extensive hunting of killer whales, including an Antarctic catch of 916 in 1979–80 alone, prompted the International Whaling Commission to recommend a ban on commercial hunting of the species pending further research. [208][209], Competition with fishermen also led to killer whales being regarded as pests. Mortality is extremely high during the first seven months of life, when 37–50% of all calves die. [103], In New Zealand, sharks and rays appear to be important prey, including eagle rays, long-tail and short-tail stingrays, common threshers, smooth hammerheads, blue sharks, basking sharks, and shortfin makos. Although there are examples of killer whales living longer, including several over 30 years old, and two captive orcas (Corky II and Lolita) are in their mid-40s.

[14], They are sometimes referred to as "blackfish", a name also used for other whale species. Some feed exclusively on fish, while others hunt marine mammals such as seals and other species of dolphin. [73] Areas which serve as major study sites for the species include the coasts of Iceland, Norway, the Valdes Peninsula of Argentina, the Crozet Islands, New Zealand and parts of the west coast of North America, from California to Alaska. These bonds can extend well into adulthood. [236][237][238][239][240], In March 2016, SeaWorld announced that they would be ending their orca breeding program and their theatrical shows. [49][132][133], Killer whales have also been observed preying on terrestrial mammals, such as deer swimming between islands off the northwest coast of North America. [176] Killer whales are unique among cetaceans, as their caudal sections elongate with age, making their heads relatively shorter. He said: “I spotted them coming down the Clyde just before lunchtime. Through photo-identification techniques, individuals were named and tracked over decades. [192], The indigenous peoples of the Pacific Northwest Coast feature killer whales throughout their art, history, spirituality and religion. According to observations in several regions, all male and female pod members participate in the care of the young. According to these myths, they took on human form when submerged, and humans who drowned went to live with them. Orcas Amaze Onlookers as Sightings Increase at Canadian Fjord Eyewitnesses in Alaska reported seeing two transients work together to tip an ice floe and slide a sleeping seal into the mouth of a third orca. Calves are born with a yellowish or orange tint, which fades to white. [190][191], A 2018 study published in Science found that global killer whale populations are poised to dramatically decline due to exposure to toxic chemical and PCB pollution. [101] Chum salmon are also eaten, but smaller sockeye and pink salmon are not a significant food item. [115] Pods of female sperm whales sometimes protect themselves by forming a protective circle around their calves with their flukes facing outwards, using them to repel the attackers. [162], (Two species or populations are considered sympatric when they live in the same geographic area and thus regularly encounter one another. [17], Types B and C live close to the ice pack, and diatoms in these waters may be responsible for the yellowish colouring of both types. These whales were beached on the day U.S. Navy destroyers were activated into sonar exercise. and, G.M. [227] Some populations, such as in Alaska's Prince William Sound, may have been reduced significantly by whalers shooting them in retaliation. These matrilineal groups are highly stable. [64][65] In 2010, the Far East Russia Orca Project (FEROP), co-founded and co-directed by Alexander M. Burdin and Erich Hoyt, filmed an adult male nicknamed Iceberg. [57][58] The skeleton of the killer whale is of the typical delphinid structure, but more robust. The shooting of about 50 seals in 1997 and 1998 at the mouth of the Puntledge River on Vancouver Island was hailed as a success when the salmon populations increased. In recent years, the extent of the public's interest in killer whales has manifested itself in several high-profile efforts surrounding individuals. Individuals separate for only a few hours at a time, to mate or forage. There, the guide and photographer Juan Carlos Lobos managed to observe and photograph the moment in which two specimens of killer whale chased, harassed and attacked an adult male elephant seal.

[53] When seen from a distance, juveniles can be confused with other cetacean species, such as the false killer whale or Risso's dolphin. Transient pods have been sighted from southern Alaska to central California. Captives have vastly reduced life expectancies, on average only living into their 20s. [193] In Nuu-chah-nulth and Kwakwaka'wakw mythology, killer whales may embody the souls of deceased chiefs. This may involve throwing it in the air, slapping it with their tails, ramming it, or breaching and landing on it. On April 1, 1989, Nootka IV of Sealand of the Pacific in Victoria, British Columbia, pulled her trainer, Henriette Huber, into the whale tank after the 6-year-old female bit down while the trainer had her hand in the mouth of the orca in order to scratch its tongue. [74], Systematic surveys indicate the highest densities of killer whales (>0.40 individuals per 100 km2) in the northeast Atlantic around the Norwegian coast, in the north Pacific along the Aleutian Islands, the Gulf of Alaska and in the Southern Ocean off much of the coast of Antarctica. Since the 1960s, "orca" has steadily grown in common use. [88], Migration patterns are poorly understood. [8] Although it has morphological similarities with the false killer whale, the pygmy killer whale and the pilot whales, a study of cytochrome b gene sequences by Richard LeDuc indicated that its closest extant relatives are the snubfin dolphins of the genus Orcaella.

Such a designation would mean that each new species becomes subject to separate conservation assessments. The firm middle and back teeth hold prey in place, while the front teeth are inclined slightly forward and outward to protect them from powerful jerking movements. Another conservation concern was made public in September 2008 when the Canadian government decided it was not necessary to enforce further protections (including the Species at Risk Act in place to protect endangered animals along their habitats) for killer whales aside from the laws already in place. This image was collected from >30m (100ft) above the whales using a small unmanned hexacopter. [150] Dialects are probably an important means of maintaining group identity and cohesiveness.

[84][85] Killer whales also appear to regularly occur off the Galápagos Islands. [161], The complex and stable vocal and behavioural cultures of sympatric groups of killer whales (Orcinus orca) appear to have no parallel outside humans and represent an independent evolution of cultural faculties. One of the whales had a seal in its mouth for several hours. Exposure to exhaust gasses from large amounts of vessel traffic are causing concern for the overall health of the 75 remaining southern resident killer whales (SRKWs) left as of early 2019. At +15.39 min the seal, which was still in the mouth of the killer whale, was taken underwater. Mitchell, E. and Baker, A. N. (1980).
