The muscles that close the mouth are enormous, and within the jaws is a set of more than 40 interlocking curved teeth.
Most of the teeth are large, measuring about 10 cm 4 inches long and 4 cm 1. The killer whale has a patchy distribution in all oceans, from the polar ice caps to the Equator , where large prey such as tuna , salmon , and seals are abundant.
Other food sources are squids , sea lions , penguins , whales , and porpoises. In the North Pacific several populations live along the Alaskan coast, in the intracoastal waterways of British Columbia and Washington , and off the coast of Baja California.
Killer whales live in small groups, usually called pods, that number fewer than 40 individuals each. Resident pods and transient pods have been differentiated within the populations of British Columbia and Washington.
Sound production and diet differ between them, with resident pods that is, those that inhabit Puget Sound and nearby coastal waters eating fish primarily salmon and transients that is, those that range over larger areas of coastal waters eating other cetaceans, seabirds, and seals.
Echolocation is used by killer whales in feeding and communication. Known to be highly intelligent, killer whales are among the few nonhuman animals to be able to recognize themselves in a mirror.
Killer whales are also one of the small number of species—along with human beings Homo sapiens , short-finned pilot whales Globicephala macrorhynchus , false killer whales Pseudorca crassidens , belugas Delphinapterus leucas , and narwhals Monodon monoceros —that experience menopause that is, the stoppage of ovulation prior to the end of their natural lives.
The circumstances under which menopause evolved in killer whales are a matter of debate, but it may have emerged in response to increases in the mortality of offspring from older generations during times when mothers and their daughters bred simultaneously.
Some scientists argue that younger females in the pod tend to focus on the success of their own offspring and may be more competitive for food resources than older females see competition.
Killer whale pods are extended families that have matriarchal hierarchies see also dominance hierarchy. The older females, tending to focus on the success of the overall pod, may be more willing to share food with the rest of the pod, thereby reducing the amount of food that could be given to their own offspring.
The evolutionary record of the genus Orcinus is scanty. The earliest fossil identified as a killer whale is O. This small mammal was about 4 metres long This implies that the ancestors of the present-day killer whale diverged from other cetaceans during the Miocene Epoch 23 million to 5.
Although the taxonomy of the killer whale is clear at the genus level and at the family level Delphinidae , relationships between killer whales and other toothed whales suborder Odontoceti are ambiguous.
Killer whales are sometimes assigned to one or another subfamily of the Delphinidae: Orcininae killer whales and kin or Globicephalinae pilot whales and kin.
More than 20 species names have been applied to the killer whale, but a consensus now recognizes only O. Evidence suggests that O.
Based on genetic analysis and studies of body size and tooth wear, scientists contend that two separate populations with distinct feeding habits and morphological characteristics have arisen.
One population , characterized by relatively small individuals with a maximum length of 6. In contrast, the other population, characterized by larger individuals that can grow to a length of 8.
There is evidence that killer whale speciation may also be occurring in the North Pacific, where as many as three genetically divergent groups exist with significantly different dispersal patterns, calls, social structure, and diets.
Killer whale. Article Media. Resident pods tend to prefer fish, while transient pods target marine mammals. All pods use effective, cooperative hunting techniques that some liken to the behavior of wolf packs.
Orcas are protective of their young, and other adolescent females often assist the mother in caring for them. Mothers give birth every three to ten years, after a month pregnancy.
They give birth to one baby at a time, which may nurse for up to two years. In most cases, the bond between juvenile and mother will eventually weaken, and the young orca will go its own way, but in some pods, the juvenile may stay with the pod it was born into its entire life.
Orcas are highly intelligent, social mammals that have long been a part of marine park entertainment, performing shows for audiences.
However, it's become increasingly clear that orcas do not thrive in captivity. They have evolved to swim up to 40 miles a day, foraging for food and exercising.
They dive to feet, several times a day, every day. Whether they're born in the wild or in captivity, all orcas born have the same innate drive to swim far and dive deep.
Artificial enclosures in captivity cannon offer that kind of range to orcas, contributing to boredom and stress.
Orcas have been seen to develop stereotypies, also known as zoochosis—repetitive patterns of activity that have no obvious function, which range from self-mutilation to rocking and swaying.
Usually related to stress and inappropriate habitats, stereotypic behavior has been documented in orcas in scientific research since the late s.
In the wild, orcas live in tight-knit family groups that share a sophisticated, unique culture that is passed down through generations, research has shown.
In captivity, orcas are kept in artificial social groups.
