Off the coast of Vestmannaeyjar, an archipelago in the south of Iceland, a massive, black fin pierces through the waves Fountains of seawater spray into the air. Killer whales have captivated us for generations, inspiring both fear and fascination. Yet despite our best efforts to control them, they have proved, time and again, that innate wildness cannot be tamed. In March of , SeaWorld pledged to permanently discontinue its trained killer whale performances, following the high-profile and gruesome death of a SeaWorld trainer in addition to mounting pressure from animal rights advocates. Then, just last month, California approved a law that outlaws killer whale breeding and captivity programs. Nothing can prepare you for the moment you first experience a pod of killer whales in the wild. Midway through the 20th century, the population of herring in the Northeast Atlantic off the coast of Iceland and Norway declined dramatically, mainly due to overfishing in those waters. In Iceland, this decline led to the near-collapse of the fishing industry. In early , the Icelandic government appealed to the United States to help them address the crisis.
On Aug. Boats, planes and bombs were used in the hunt and resulting capture, and five orcas died. Juveniles were separated from their pods and netted off to await transport into captivity at amusement parks. During those weeks between capture and transport, the adult orcas never left the abduction site, and the sound of their grief-filled keening rang through the cove. When Tokitae arrived at the Miami Seaquarium on Sept.
Last month SeaWorld announced it would stop breeding orcas, but how To date SeaWorld has not published any research about its orcas’.
TakePart reports on the movement to free killer whales held in captivity at marine parks. Rounding a rocky headland on Hanson Island, we pull into a sheltered cove surrounded by thick stands of cedar, fir, and spruce. In the distance, snow-flecked peaks tower above nearby Vancouver Island. As I survey the serene swath of wilderness, I find it hard not to agree. Corky the killer whale is one of the star performers at faraway SeaWorld in San Diego.
In , at around age four, the orca was snatched from her family which still patrols this area each summer in a notorious roundup in Pender Harbor, on the British Columbian mainland. Six whales were removed from their pod and sold to theme parks and aquariums, hungry for more of the crowd-pleasing ticket sellers. Now, nearly 47 years later, Corky is the longest-held captive orca. Their lives are vastly different from those of orcas in the ocean, which typically stay with their families for life; captive orcas are often removed from their mothers, sometimes at very young ages.
Orcas in the wild can swim up to miles per day; orcas in tanks are lucky to swim laps. Most studies show that death rates for captive orcas are higher than for wild ones. Spong and his wife, Helena Symonds, who operate the nonprofit research center OrcaLab , have been hoping to return Corky to her native waters for decades. They even envision the whale rejoining her pod in the wild.
But the obstacles have been daunting.
SeaWorld’s orcas will be last generation at parks
The boat circled a pod of killer whales feeding peacefully on fish. The crew had already pursued several different whale groups over the past few days with no success. So this time, the crew was patient and kept circling to lull the animals into complacency. When the whales seemed calm enough, the crew flung the encircling nets, and quickly realized how many animals they faced: About 20 whales, adults and calves, frantically swam around inside the enclosure.
Within minutes, the animals discovered escape routes and rushed to break free. The net emptied fast, but the hunters lucked out.
Should killer whales Skype? A new study suggests that virtual links between captive orca populations might be one way to improve the lives of.
Feared by whalers who watched them feed off dead whales they were hauling to their ships, orcas were called killer whales. Later, captured, forced to perform tricks, these animals are now revered, as they have always been by indigenous peoples, and sea aquariums are now facing pressure to release them. The Whale Sanctuary team will present their proposal to the public, along with unveiling several site possibilities, two of which are located in the San Juans on Sunday, July 21, p.
Captivity has been known to have negative health effects on cetaceans. In the wild, orcas life expectancy is on par with humans. Granny, a matriarch from J-pod lived to be an estimated age of plus years old. In captivity, however, Marino said, on average orcas only live 20 years.
A half-century in a bathtub: Lolita, an orca, has been in captivity long enough
This page details every killer whale that has died in captivity since Two formerly captive killer whales Ishmael and Keiko — found in bold are not included in the total number given at the top of the page as neither died in captivity. Ishmael, a U. Keiko, star of Free Willy, was famously rehabilitated and released into the wild where he interacted with wild orcas and travelled miles across the Atlantic from Iceland to Norway.
In December Keiko passed away at 26 years old from what was believed to be Acute Pneumonia — a common disease both in captivity and in the wild. Also not included in the total at the top of the page are mortalities during capture operations which are as follows:.
Two formerly captive killer whales (Ishmael and Keiko – found in bold) are not Captive Mother / Father, Sex, Origin, Capture / Birth Date, Est. Age at Capture.
Roughly half of all Southern Resident killer whales Orcinus orca were removed from the population due to shooting prior to and live capture in the s and s, but once these activities were banned, the population rebounded from 71 individuals in to 98 in However, the population has declined since, and as of June stands at 76, the lowest it has been in 34 years. The prospects for recovery appear bleak, as since there has been just one birth that have produced a calf who survived to juvenile age.
Killer whales are found in every ocean, but the species is segmented into many small populations , at least two of which are likely separate species, that differ genetically, as well as in appearance, behavior, social structure, feeding strategies and vocalizations. Southern Residents are Chinook salmon specialists, feeding on Chinook year-round, especially in the spring and summer when they occupy inland waters and it is their primary prey.
During the fall and winter, when they are dispersed widely, they add other salmon species coho in fall and chum in winter and some demersal fishes to their diet e. The three Southern Resident pods J, K and L differ in a number of characteristics, including pod size, dialect and home ranges. Within each pod there are several family units, each descended from a single female ancestor.
In several cases, although the matriarch has died, the family unit has remained together.
Can orcas ever be healthy in captivity?
British Broadcasting Corporation Home. The recent attack by a captive orca on its trainer at a SeaWorld facility in Orlando, Florida, has again raised questions about our relationship with these top marine predators. No-one knows what triggered the latest incident, and experts agree that it is almost impossible to determine why the orca, called Tilikum, reacted as it did. But it does highlight the tensions that occur when we choose to interact closely with these huge animals.
It is also debatable what to do with those orcas, also known as killer whales, that remain in captivity. Contrary to popular perception, attacks by wild orcas on people have also been recorded, though no-one has been hurt.
Killer Controversy: Why Orcas Should No Longer Be Kept in Captivity. Humane Thus to date the maximum lifespan of captive orcas has.
Killer whales held in captivity live shorter lives than wild whales, according to a new study. This may not be the most surprising scientific finding, but the data adds to the debate over the ethics of keeping captive whales. Twenty years ago, scientists published a study looking at how well killer whales fare in captivity. They found that before , killer whales in captivity had a 94 percent chance of surviving the next year compared to a 98 percent chance in the wild.
Since , that percentage for captive animals has crept up to match the number for wild killer whales. As the researchers found, not all aquariums are equal. Comparing longevity at American theme parks to similar tourist attractions in Russia and China, the researchers found that killer whales in the United States live roughly eight years longer than the ones held in foreign facilities. SeaWorld trainers emphasize in their advertising material that killer whales live as long in their facilities as in the wild.
Jett is a visiting researcher at Stetson University in Texas, but he is also a former trainer at SeaWorld. Jett and the other author who worked on the paper— Jeffrey Ventre , a rehabilitation doctor and former chiropractor from Washington State—also both appeared in the documentary Blackfish , a film critical of theme parks like SeaWorld.
But anyone who understands the science will read it and immediately they will recognize that I had no agenda. The debate over captive whales is a complex one, but what this most recent study could do is help researchers better understand what causes killer whale deaths in captivity, says Jett. Separating calves from their mothers, for instance, could increase the chance of the calf dying from stress.
SeaWorld Welcomes Its Last Orca Born In Captivity
Captive killer whales are live killer whales Orcinus orca which are held in captivity by humans, often for breeding or performance purposes. The practice of capturing and displaying these whales in exhibitions began in the s, soon becoming popular attractions at public aquariums and aquatic theme parks due to their intelligence, trainability, striking appearance, playfulness, and sheer size. As of August, , there were 60 orcas in captivity worldwide , 33 of which are captive-born.
The practice of keeping killer whales in captivity is controversial, due to the separation of their familial “pod” during capture, and their living conditions and health in captivity. Of the reported killer whale attacks in the wild, none have been fatal. Killer whales are large, active and intelligent.

The Animal Legal Defense Fund, along with a coalition of animal protection, environmental, and marine conservation groups, is working to ensure that this generation of captive orcas in Florida is the last. This legislation would make it illegal to hold orcas in captivity for any purpose grandfathering those already in captivity in Florida , breed captive orcas, and transport captive orcas into Florida or out of North America, unless provided by federal law or to rehome to sanctuary.
Southern Resident Killer Whale
Dolphins would join Orcas in an updated captivity ban bill, effectively shutting down large parts of animal parks such as SeaWorld, but also leaving open the question of helping them medically in such places. Further provisions restrict transport and breeding of cetaceans in the state. No dates have been set yet for proposed end dates.
Galgiani has also written previous bills on expanding animal welfare, such as SB in , a law that came into effect this year that banned animal testing in cosmetics in the state.
In other words, orcas are highly intelligent, social, and emotional animals, and, as I will argue, may be inadequately stimulated in captivity. Page 2. The topic of.
An international research team has undertaken the first in-depth investigation of the teeth of captive orca killer whales and have found them a sorry state, which raises serious concerns for these majestic mammals’ overall health and welfare. Anyone with a toothache knows how painful and distracting that can be — in orca which have around 48 large teeth, a sore tooth is likely no less painful or debilitating than for a person.
Now, a new international study published in the journal Archives of Oral Biology , found that every individual examined had damaged teeth. We found that the more than 65 per cent possessed moderate to extreme tooth wear in their lower jaws, mostly as a result of chewing concrete and steel tank surfaces. Additionally, the researchers found that more than 61 per cent of the orca they studied have “been to the dentist” to have their teeth drilled. Officially termed a “modified pulpotomy,” a hole is drilled into the tooth to extract the soft pulpy tissue inside.
Study co-author Dr Carolina Loch, a Faculty of Dentistry researcher at New Zealand’s University of Otago, specializes in the dentition of whales and dolphins, and says that unlike us, the resultant hole is not filled or capped, but rather is left open for the rest of the animal’s life, requiring daily flushing with chemicals to keep the teeth empty of food and bacteria in an attempt to manage resulting infection. Dr Jeff Ventre, another of the study authors, also an ex-orca trainer and now a medical doctor, says that he had drilled orca teeth in his former work.
Dr Loch added that a drilled tooth is severely weakened and if any other trauma occurs, fractures will happen. During his time as a trainer, Dr Ventre says that he had witnessed “whales breaking their teeth on steel gates while jaw popping.
Freeing Whales and Dolphins from Captivity
Saturday marks 50 years since Lolita, or Tokitae, the lone orca held at the Miami Seaquarium, was kidnapped from her family. For decades, the officials charged with protecting this critically endangered, extremely intelligent and highly complex animal have failed her. Against all odds, Lolita has survived. On Aug.
out to do just that, going to great lengths to capture a killer whale in the wild. Captive Orcas Demonstrate a Problem with Animal Welfare Laws nothing new. To date, private action has had limited success The most.
Orca behaviors interacting with humans within apparent friendship bonds are reviewed, and some impediments to the human evaluation of delphinid intelligence are discussed. The subsequent involvement of these orcas and their offspring in aggressive incidents with humans is also documented and examined. This is particularly relevant given that the highest recorded rates of aggressive incidents have occurred among orcas who had previously established unstructured human friendship bonds prior to their inclusion within oceanaria performances.
It is concluded that the confinement of orcas within aquaria, and their use in entertainment programs, is morally indefensible, given their high intelligence, complex behaviors, and the apparent adverse effects on orcas of such confinement and use. Based on neuroanatomical indices such as brain size and encephalization quotient, orcas are among the most intelligent animals on Earth. They display a range of complex behaviors indicative of social intelligence, but these are difficult to study in the open ocean where protective laws may apply, or in captivity, where access is constrained for commercial and safety reasons.
We observed in the animals what appeared to be pranks, tests of trust, limited use of tactical deception, emotional self-control, and empathetic behaviors. Our observations were consistent with those of a former Seaworld trainer, and provide important insights into orca cognition, communication, and social intelligence. The orcas who previously established apparent friendships with humans were most affected, although significant aggression also occurred in some of their descendants, and among the orcas they lived with.
Cognition includes the various mental actions and processes that underlie intelligence. While intelligence is an amorphous term with different definitions and uses by diverse groups [ 2 ], legal and social perceptions regarding animal intelligence impact animal conservation and welfare [ 3 , 4 ].
Watch What Happens When You Free a Killer Whale
Because a female trainer, Dawn Brancheau, was killed this week by a captive killer whale which dragged her into its tank at the SeaWorld centre in Orlando, Florida. Well, yes and no. The name killer whale originally came from the fact that these striking, large and fierce animals had been seen to be “killers of whales” — and they do indeed sometimes hunt other whale species in the open ocean The name biologists increasingly prefer to use is orca, the second half of its scientific name, Orcinus orca.
The orca Takara gave birth to a calf Wednesday at the SeaWorld park in San Antonio, Texas. company announced last March that it would stop breeding orcas in captivity. The calf’s gender will be confirmed at a later date.
All rights reserved. Orcas, or killer whales, are the largest of the dolphins and one of the world’s most powerful predators. They’re immediately recognizable by their distinctive black-and-white coloring. Smart and social, orcas make a wide variety of communicative sounds, and each pod has distinctive noises that its members will recognize even at a distance. They use echolocation to communicate and hunt, making sounds that travel underwater until they encounter objects, then bounce back, revealing their location, size, and shape.
Though they often frequent cold, coastal waters, orcas can be found from the polar regions to the Equator. They’re at the top of the food chain and have very diverse diets, feasting on fish, penguins, and marine mammals such as seals, sea lions, and even whales, employing teeth that can be four inches long. They are known to grab seals right off the ice. They also eat fish, squid, and seabirds. Orcas hunt in deadly pods, family groups of up to 40 individuals.
