Clicks are believed to be used primarily for navigation and discriminating prey and other objects in the surrounding environment, but are also commonly heard during social interactions.
Northeast Pacific resident groups tend to be much more vocal than transient groups in the same waters.
In contrast, the marine mammal prey of transients hear well underwater at the frequencies used in killer whale calls. As such, transients are typically silent, probably to avoid alerting their mammalian prey.
Residents are only silent when resting. All members of a resident pod use similar calls, known collectively as a dialect. Dialects are composed of specific numbers and types of discrete, repetitive calls.
They are complex and stable over time. Similarity in dialects likely reflects the degree of relatedness between pods, with variation building over time.
The use of both call types is called biphonation. The increased subset call types may be the distinguishing factor between pods and inter-pod relations.
Dialects of killer whales not only distinguish them between pods, but also between types. All members of the North American west coast transient community express the same basic dialect, although minor regional variation in call types is evident.
Preliminary research indicates offshore killer whales have group-specific dialects unlike those of residents and transients.
The vocalizations of killer whales in other parts of the world have also been studied. Norwegian and Icelandic herring-eating orcas appear to have different vocalizations for activities like hunting and traveling.
Killer whales have the second-heaviest brains among marine mammals  after sperm whales , which have the largest brain of any animal.
They can be trained in captivity and are often described as intelligent,   although defining and measuring "intelligence" is difficult in a species whose environment and behavioral strategies are very different from those of humans.
Killer whales imitate others, and seem to deliberately teach skills to their kin. Off the Crozet Islands , mothers push their calves onto the beach, waiting to pull the youngster back if needed.
People who have interacted closely with killer whales offer numerous anecdotes demonstrating the whales' curiosity, playfulness, and ability to solve problems.
Alaskan killer whales have not only learned how to steal fish from longlines , but have also overcome a variety of techniques designed to stop them, such as the use of unbaited lines as decoys.
A researcher described what happened next:. It worked really well for a while. Then the whales split into two groups.
It didn't even take them an hour to figure it out. They were so thrilled when they figured out what was going on, that we were playing games.
They were breaching by the boats. In other anecdotes, researchers describe incidents in which wild killer whales playfully tease humans by repeatedly moving objects the humans are trying to reach,  or suddenly start to toss around a chunk of ice after a human throws a snowball.
The killer whale's use of dialects and the passing of other learned behaviours from generation to generation have been described as a form of animal culture.
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.
Two species or populations are considered sympatric when they live in the same geographic area and thus regularly encounter one another.
In , the IUCN International Union for Conservation of Nature changed its assessment of the killer whale's conservation status from conservation dependent to data deficient , recognizing that one or more killer whale types may actually be separate, endangered species.
Like other animals at the highest trophic levels , the killer whale is particularly at risk of poisoning from bioaccumulation of toxins, including polychlorinated biphenyls PCBs.
When food is scarce, killer whales metabolize blubber for energy, which increases pollutant concentrations in their blood. In the Pacific Northwest , wild salmon stocks, a main resident food source, have declined dramatically in recent years.
In , the United States government listed the southern resident community as an endangered population under the Endangered Species Act.
They do not breed outside of their community, which was once estimated at around animals and later shrank to around These deaths can be attributed to declines in Chinook salmon.
Scientist Ken Balcomb has extensively studied killer whales since ; he is the research biologist responsible for discovering U.
Navy sonar may harm killer whales. The whales seemed "agitated and were moving haphazardly, attempting to lift their heads free of the water" to escape the sound of the sonars.
The sound originated from a U. Navy frigate 12 miles 19 kilometers distant, Balcomb said. Three years prior to Balcomb's discovery, research in the Bahamas showed 14 beaked whales washed up on the shore.
These whales were beached on the day U. Navy destroyers were activated into sonar exercise. These six dead whales were studied, and CAT scans of two of the whale heads showed hemorrhaging around the brain and the ears, which is consistent with decompression sickness.
Another conservation concern was made public in September 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.
In response to this decision, six environmental groups sued the federal government, claiming killer whales were facing many threats on the British Columbia Coast and the federal government did nothing to protect them from these threats.
Underwater noise from shipping, drilling, and other human activities is a significant concern in some key killer whale habitats, including Johnstone Strait and Haro Strait.
Killer whales also avoided the surrounding waters. Eleven members about half of one resident pod disappeared in the following year. The spill damaged salmon and other prey populations, which in turn damaged local killer whales.
By , scientists estimated the AT1 transient population considered part of a larger population of transients , numbered only seven individuals and had not reproduced since the spill.
This population is expected to die out. A study published in Science found that global Killer whale populations are poised to dramatically decline due to exposure to toxic chemical and PCB pollution.
The indigenous peoples of the Pacific Northwest Coast feature killer whales throughout their art , history, spirituality and religion.
The Haida regarded killer whales as the most powerful animals in the ocean, and their mythology tells of killer whales living in houses and towns under the sea.
According to these myths, they took on human form when submerged, and humans who drowned went to live with them. The Maritime Archaic people of Newfoundland also had great respect for killer whales, as evidenced by stone carvings found in a 4,year-old burial at the Port au Choix Archaeological Site.
In the tales and beliefs of the Siberian Yupik people, killer whales are said to appear as wolves in winter, and wolves as killer whales in summer.
In Western cultures , killer whales were historically feared as dangerous, savage predators. Of the very few confirmed attacks on humans by wild killer whales, none have been fatal.
In the s, a surfer in California was bitten, and in , a boy in Alaska who was splashing in a region frequented by harbor seals was bumped by a killer whale that apparently misidentified him as prey.
Competition with fishermen also led to killer whales being regarded as pests. In the waters of the Pacific Northwest and Iceland , the shooting of killer whales was accepted and even encouraged by governments.
Navy claimed to have deliberately killed hundreds of killer whales in Icelandic waters in with machine-guns, rockets, and depth charges.
Western attitudes towards killer whales have changed dramatically in recent decades. In the mids and early s, killer whales came to much greater public and scientific awareness, starting with the first live-capture and display of a killer whale known as Moby Doll , a resident harpooned off Saturna Island in To the surprise of those who saw him, Moby Doll was a docile, nonaggressive whale that made no attempts to attack humans.
Between and , 50 killer whales from the Pacific Northwest were captured for display in aquaria , and public interest in the animals grew.
In the s, research pioneered by Michael Bigg led to the discovery of the species' complex social structure, its use of vocal communication, and its extraordinarily stable mother—offspring bonds.
Through photo-identification techniques, individuals were named and tracked over decades. Bigg's techniques also revealed the Pacific Northwest population was in the low hundreds rather than the thousands that had been previously assumed.
The public's growing appreciation also led to growing opposition to whale—keeping in aquarium. Only one whale has been taken in North American waters since In recent years, the extent of the public's interest in killer whales has manifested itself in several high-profile efforts surrounding individuals.
Following the success of the film Free Willy , the movie's captive star Keiko was returned to the coast of his native Iceland in She became the first whale to be successfully reintegrated into a wild pod after human intervention, crystallizing decades of research into the vocal behavior and social structure of the region's killer whales.
However, his case was marked by controversy about whether and how to intervene, and in , Luna was killed by a boat propeller.
The earlier of known records of commercial hunting of killer whales date to the 18th century in Japan. During the 19th and early 20th centuries, the global whaling industry caught immense numbers of baleen and sperm whales, but largely ignored killer whales because of their limited amounts of recoverable oil , their smaller populations, and the difficulty of taking them.
Between and , Japan took 1, killer whales although the Ministry of the Environment claims that there had been domestic catches of about 1, whales between late s to s  and Norway took Today, no country carries out a substantial hunt, although Indonesia and Greenland permit small subsistence hunts see Aboriginal whaling.
Other than commercial hunts, killer whales were hunted along Japanese coasts out of public concern for potential conflicts with fisheries.
Such cases include a semi-resident male-female pair in Akashi Strait and Harimanada being killed in the Seto Inland Sea in ,   the killing of five whales from a pod of 11 members that swam into Tokyo Bay in ,  and a catch record in southern Taiwan in the s.
Killer whales have helped humans hunting other whales. Whalers more often considered them a nuisance, however, as orcas would gather to scavenge meat from the whalers' catch.
The killer whale's intelligence , trainability, striking appearance, playfulness in captivity and sheer size have made it a popular exhibit at aquaria and aquatic theme parks.
From to , 55 whales were taken from the wild in Iceland, 19 from Japan, and three from Argentina. These figures exclude animals that died during capture.
Organizations such as World Animal Protection and the Whale and Dolphin Conservation campaign against the practice of keeping them in captivity.
Captives have vastly reduced life expectancies, on average only living into their 20s. Wild males who survive infancy live 31 years on average, and up to 50—60 years.
Critics claim captive life is stressful due to these factors and the requirement to perform circus tricks that are not part of wild killer whale behavior, see above.
A study coauthored by staff at SeaWorld and the Minnesota Zoo indicates that there is no significant difference in survivorship between free-ranging and captive killer whales.
The authors speculate about the future utility of studying captive populations for the purposes of understanding orca biology and the implications of such research of captive animals in the overall health of both wild and marine park populations.
As of March , SeaWorld has announced that they will be ending their orca breeding program and their theatrical shows. They previously announced, in November , that the shows would be coming to an end in San Diego but it is now to happen in both Orlando and San Antonio as well.

You can't, you just can't. The dramatic fight between Captain Nolan and the whale could have easily become silly, but it doesn't. The Arctic Circle is accurately represented as a cold place with many iceberg, some of which whales can thwack themselves upon catapulting middle-aged Irishmen forty feet in the air.
Keep in mind, also, this was done without the use of computer graphics. Steven Spielberg did not even put the shark in Jaws until over halfway through the film.
To hide a machine so fake that I can only assume one of his children made it at camp. The mechanical killer whale in Orca is almost indistinguishable from the stock footage of killer whales continually played throughout the movie.
In , how many directors were brave enough to shoot a killer whale jumping from one side of the boat, eating actor Robert Carradine, and landing on the other side?
Just one, Michael Anderson. His bold choices along with screenwriters Luciano Vincenzoni and Sergio Donati who both show an above average command of the English languages for native-born Italian speakers make the film a statement not only about whale hunting and whale forgiveness seeking, but also about humanity.
Charlotte Rampling's appeal to Nolan not to go fight the whale just because the whale wants revenge is not just about social protocols of how to make it up to the father of a whale baby you accidentally killed, but also an argument against the death penalty.
Will Sampson's pointless death is an indictment of the senseless slaughter of tens of millions of Native Americans. When the whale knocks down Captain Nolan's house without any explanation of this whale became such a genius that he can not only knows to knock down structural supports but also can look up addresses in the phone book, it directly shows how our incursion into the world of nature is two-fold.
Robert Carradine's tragic death in the film is social commentary on the probability of being eaten if you stand around on a boat being followed by a crazed killer whale.
And probably also something about Vietnam, I assume. And while most in Hollywood choose not to admit it, many have ripped off Orca.
The dead baby scene in Trainspotting is suspiciously reminiscent of the dead whale fetus scene in Orca. The creepy quasi-romance between an intelligent female and a somewhat crazy violent child murderer is directly stolen by George Lucas for Star Wars: The use of icebergs is blatantly co-opted by Titanic, and I have never heard James Cameron so much as thank Michael Anderson.
And don't even get me started on Free Willy. Orca is a complicated story. If you only enjoy movies with obvious heroes and villains, this is not for you.
The characters are conflicted. Take for instance how the killer whale jumps for joy after biting off Bo Derek's leg. The whale shows both glee in his jumps, but also the pain of having lost his family and never being able to bring them back no matter how hard he fights those who took them from him.
You see, the only thing black and white in this movie is the killer whale itself. While Orca does not now get the respect it deserves, in time people will realize its genius.
Just as people did not understand gravity or continental drift, in time they will come to recognize Orca as the greatest cinematic achievement of all time.
