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.
SeaWorld’s orcas will be last generation at parks
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.
Orcas, known popularly as killer whales, are the subject of a new documentary that hopes to bring attention to problems they face in captivity.
CNN The killer whales currently in SeaWorld’s care will be the last generation of the mammals enclosed at the water parks, according to a company announcement posted on its website.

A captive orca and a chance for our redemption
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.
“We believe it is in the best interest of the captive orcas at SeaWorld that the truth come out. A speedy trial will achieve that.” In February the.

Southern Resident Killer Whale
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.

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.
Attacks by orcas are rare, but they highlight the tensions between these large marine predators and people.
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. A few matrilines are functionally extinct as they are composed only of one or more males.
However, with modern impacts on their prey base, opportunistic shooting prior to the s, and the live capture or killing of nearly 70 Resident and Transient killer whales for marine parks and display from to , the first complete count found just 71 whales in With the cessation of capture and shootings, the population slowly increased to a peak of whales in the mids.
SeaWorld Welcomes Its Last Orca Born In Captivity
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.
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.
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.
Moreover, the legislation would guarantee that those orcas already held in captivity in Florida would only be held for research or rehabilitation purposes and that any public displays must be strictly educational.
What Will It Take to End International Killer Whale Capture?
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.
In the wild, orcas can swim well over miles a day and dive hundreds — even thousands — of feet deep. The Seaquarium holds Lolita, who.
Should some of the most social, intelligent and charismatic animals on the planet be kept in captivity by human beings? That is a question asked more frequently than ever by both scientists and animal welfare advocates, sometimes about close human cousins like chimpanzees and other great apes, but also about another animal that is remarkable for its intelligence and complex social organization — the killer whale, or orca.
But in the last half century these elegant black-and-white predators — a threat to seals and other prey as they cruise the oceans, but often friendly to humans in the wild — have joined the pantheon of adored wildlife, along with the familiar polar bears, elephants and lions. With life spans that approach those of humans, orcas have strong family bonds, elaborate vocal communication and cooperative hunting strategies.
And their beauty and power, combined with a willingness to work with humans, have made them legendary performers at marine parks since they were first captured and exhibited in the s. They are no longer taken from the wild as young to be raised and trained, but are bred in captivity in the United States for public display at marine parks. Some scientists and activists have argued for years against keeping them in artificial enclosures and training them for exhibition.
Watch What Happens When You Free a Killer Whale
Should killer whales Skype? A new study suggests that virtual links between captive orca populations might be one way to improve the lives of these marine mammals. The keeping of orcas, or killer whales, in captivity has been a matter of public controversy, especially since the release of the documentary ” Blackfish ” in The film centers on the killing of a SeaWorld trainer , Dawn Brancheau, by a captive killer whale that had been captured from the wild in
In captivity, orcas are kept in artificial social groups. Captive-born orcas are often transferred between facilities, breaking up social relationships. The stress of.
Todd R. Robeck, Kevin Willis, Michael R. Scarpuzzi, Justine K. Data collected on life-history parameters of known-age animals from the northern NR and southern resident SR killer whales Orcinus orca of the eastern North Pacific were compared with life-history traits of killer whales located at SeaWorld SEA facilities. For captive-born SEA animals, mean age and body length at 1st estrus was 7.
Average calf survival rate to 2 years of age for SEA animals 0. The SR 0. Based on ASR, median and average life expectancy were These data present evidence for similar life-history parameters of free-ranging and captive killer whale populations and the reproductive potential and survivorship patterns established herein have application for use in future research concerning the overall health of both populations.
With estimated worldwide population levels at a minimum of 50, Taylor et al. The killer whale populations in the eastern North Pacific Ocean are by far the most studied and best understood. Three clearly distinct ecotypes, residents, transients, and offshores, have been identified based primarily on migratory patterns and prey sources reviewed by National Marine Fisheries Service Within the well-studied resident ecotypes inhabiting the Pacific Northwest, animals remain in their natal group for most, if not all, of their life, whereas evidence for the lesser-studied transients and the poorly studied offshores indicates a fluid population structure with temporary or permanent dispersal of offspring from the natal group Bigg et al.
