[6] Konrad Gessner wrote the first scientific description of a killer whale in his Piscium & aquatilium animantium natura of 1558, part of the larger Historia animalium, based on examination of a dead stranded animal in the Bay of Greifswald that had attracted a great deal of local interest. [203] The first written description of a killer whale was given by Pliny the Elder circa AD 70, who wrote, "Orcas (the appearance of which no image can express, other than an enormous mass of savage flesh with teeth) are the enemy of [other kinds of whale]... they charge and pierce them like warships ramming. Males typically range from 6 to 8 metres (20 to 26 ft) long and weigh in excess of 6 tonnes (5.9 long tons; 6.6 short tons). – 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.). Orca Killer Whale Totem – Are You In Danger? Eventually, they separate the pair and surround the calf, drowning it by keeping it from surfacing, and may consume only its jaw and tongue. The nudging, biting and ramming attacks, on medium-size sailing boats sailing at moderate speed, concentrated on the rudder, with some impacts on the hull. [151], Norwegian and Icelandic herring-eating orcas appear to have different vocalizations for activities like hunting. [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. While the incidents were terrifying, no people were injured. 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. This may involve throwing it in the air, slapping it with their tails, ramming it, or breaching and landing on it. The diver was safely recovered to the LARS basket and brought back to surface as the Leopard Seal got closer and closer. Another orca came along and took the seal in its mouth, and then another came alongside the orca with the seal. [194], The Maritime Archaic people of Newfoundland also had great respect for killer whales, as evidenced by stone carvings found in a 4,000-year-old burial at the Port au Choix Archaeological Site. These figures exclude animals that died during capture. A researcher described what happened next: It worked really well for a while. Research conducted under NMFS Permit No. [54], The killer whale's teeth are very strong, and its jaws exert a powerful grip; the upper teeth fall into the gaps between the lower teeth when the mouth is closed. Salmon account for 96% of northeast Pacific residents' diet, including 65% of large, fatty Chinook. [3] Depletion of prey species, pollution, large-scale oil spills, and habitat disturbance caused by noise and conflicts with boats are the most significant worldwide threats. [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. Examination of his teeth indicated he died around age 35,[174] but this method of age determination is now believed to be inaccurate for older animals. Leatherwood, Stephen and Larry J. Hobbs (1988). killer whale teeth stock pictures, royalty-free photos & images. Orcas, or killer whales, are the largest of the dolphins and one of the world's most powerful predators. Resident dialects contain seven to 17 (mean = 11) distinctive call types. These matrilineal groups are highly stable. Published directories contain identifying photographs and names for hundreds of North Pacific animals. [88][89] They have also been found in the Fraser River in Canada and the Horikawa River in Japan. In contrast, the marine mammal prey of transients hear whale calls well. [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. [229], As a response to this, in 2017 boats off the British Columbia coast now have a minimum approach distance of 200 metres compared to the previous 100 metres. [189], The Exxon Valdez oil spill adversely affected killer whales in Prince William Sound and Alaska's Kenai Fjords region. [157], Killer whales imitate others, and seem to deliberately teach skills to their kin. Wild males who survive infancy live 31 years on average, and up to 50–60 years. ... octopus and seabirds - and will even attack and eat seals and whales. It generally eats a variety of animals such as other whales, fish, penguins, seals, and sea lions (ACS, n.d.). [153], Killer whales have the second-heaviest brains among marine mammals[154] (after sperm whales, which have the largest brain of any animal). Variations such as nicks, scratches, and tears on the dorsal fin and the pattern of white or grey in the saddle patch are unique. When food is scarce, killer whales metabolize blubber for energy, which increases pollutant concentrations in their blood. Unlike residents, extended or permanent separation of transient offspring from natal matrilines is common, with juveniles and adults of both sexes participating. [50], There are seven identified ecotypes inhabiting isolated ecological niches. By 2009, scientists estimated the AT1 transient population (considered part of a larger population of 346 transients), numbered only seven individuals and had not reproduced since the spill. However, the devastation of great whale populations by unfettered whaling has possibly reduced their availability for killer whales, and caused them to expand their consumption of smaller marine mammals, thus contributing to the decline of these as well. [44], Mammal-eating killer whales in different regions were long thought likely to be closely related, but genetic testing has refuted this hypothesis.
