World Sea Turtle Day is a day to honor and highlight the importance of sea turtles. It is on June 16th because that was the birthdate of Dr. Archie Carr, the Sea Turtle Conservancy’s founder and the ‘father of sea turtle biology.’
Sea turtles have been around for at least 110 million years, as far back as the Cretaceous period and the dinosaurs. They spend their lives in the sea, except for nesting, and swim in almost all oceans. Sea turtles navigate through their sensitivity to the Earth’s magnetic fields. All species of female sea turtles return to the same exact beach they hatched on to nest.

Endangered
Six out of seven species of sea turtles are threatened with extinction, according to the IUCN Red List. The 7th is listed as ‘data deficient.’1

Importance
“Sea turtles are a fundamental link in marine ecosystems.” -World Wildlife Fund
Sea turtles keep the natural ocean environment and the food chain balanced. Following are specific ways in which they provide this balance.
Balancing the Food Chain
The largest sea turtles, the leatherbacks, consume up to 440 pounds of jellyfish daily. Loggerheads and Green sea turtles also eat them. As sea turtle populations decline, jellyfish populations increase. This not only affects humans, but it affects fish populations. “Declining fish stocks leave jellyfish with less competition for food, resulting in proliferation of jellyfish around the world. The increase in jellyfish is already proving detrimental to the recovery of fish stocks since jellyfish prey on fish eggs and larvae.”3 So the fewer sea turtles, the more jellyfish, and the fewer fish worldwide. This alone could cause devastation.
Certain fish “clean” the barnacles, algae, and epibionts (organisms that survive by living on other organisms) from sea turtles’ bodies and shells, sometimes providing their sole food source. Without turtles, these organisms would have to find another, potentially unsuccessful, food source. “Species associated with a host, such as sea turtles, are important to generating and maintaining diversity throughout the world’s oceans.”4
Sea turtles also provide food to many other species as prey. Many predators eat eggs and hatchlings, and even juvenile sea turtles. Sharks and killer whales sometimes eat adult sea turtles.
Last, but not least, some species, such as loggerheads, consume crustaceans. While eating they break the shells into fragments and create trails in sediment along the ocean floor, practices that both contribute to what is known as ‘nutrient cycling.’

Seagrass control
Sea turtles are one of the few animals that eat seagrass, especially Green sea turtles. It needs to be cut short constantly to stay healthy and to keep growing. Seagrass beds are important because they are the breeding and developmental grounds for many species of fish, shellfish, and crustaceans. Those species are consumed by many other species, so lower levels of seagrass impact the food chain, all the way up to humans.5
Additionally, seagrass control provides balance to the ocean. “Without constant grazing, seagrass beds become overgrown and obstruct currents, shade the bottom, begin to decompose and provide suitable habitat for the growth of slime molds. Older portions of seagrass beds tend to be overgrown with microorganisms, algae, invertebrates and fungi.” The Caribbean has seen a sharp decrease in Green sea turtles and thus a loss of productivity in commercially fished species.6
“All parts of an ecosystem are important, if you lose one, the rest will eventually follow.” -Sea Turtle Conservancy7
Dune Protection and Prevention of Beach Erosion
Beaches and dunes do not get a lot of nutrients because sand doesn’t hold them. However, all of the sea turtle nests, eggs, and hatchlings don’t make it to the sea, leaving valuable nutrients behind, such as nitrogen, phosphorus, and potassium, that allow the dunes to thrive. Even the eggshells from hatched eggs provide some nutrients. This is called nutrient cycling. “Dune vegetation is able to grow and become stronger with the presence of nutrients from turtle eggs. As the dune vegetation grows stronger and healthier, the health of the entire beach/dune ecosystem becomes better. Stronger vegetation and root systems helps to hold the sand in the dunes and helps protect the beach from erosion.”8 But as sea turtles decline, nests decline, and the beaches start eroding.
Additionally, sea turtle eggs, shells, and even hatchlings provide food for other species, which then redistribute the nutrients through their feces. Those nutrients also feed the vegetation that provides stabilization to the dunes.

Coral Reef Development
Hawksbill Sea Turtles, which eat a lot of sea sponges, help protect the coral reefs. “Sponges compete aggressively for space with reef-building corals. By removing sponges from reefs, hawksbills allow other species, such as coral, to colonize and grow.” Without sea turtles, sponges could start to dominate reef communities and limit the growth of corals, and altering the entire coral ecosystem.9
“These amazing creatures are endangered by human interactions, both intentional and unintentional: fishing lines, nets, boat hulls, propellers, and plastic debris, which the turtles mistake for jellyfish and ingest.” -Joel Sartore10

What You Can Do
There are so many things you can do to help protect sea turtles! Here’s a quick list, but you can check out my article “Sea Turtles are Endangered” for detailed information.
Avoid plastic bags. This is a big one because turtles, especially leatherbacks, mistake floating plastic shopping bags for jellyfish, and ingesting bags kills them.
Stop using disposable plastic straws; decline them at restaurants. If you really must have one, carry a metal or glass straw with you.
Keep beaches clean. Litter on beaches prevents hatchlings from reaching the sea.
Turn off the lights.
Use coral reef-friendly sunscreen.
Buy sustainable seafood.
Do your part to slow climate change.
Reduce the chemicals you use in your yard and dispose of others properly through the hazardous waste collection in your area.
Don’t buy products made from real turtle shells.
Make turtle cookies. I know that sounds funny, but if you have children, cookies are a great conversation starter. Even coworkers would give you a few minutes of listening while enjoying them.
Educate others. Try the cookie trick.
Stop releasing helium balloons.
Recycle, or better yet, don’t buy plastic as much as possible.

Adopt-A-Turtle!
There are numerous programs that offer sea turtle nest “adoption” for donation. You can do a quick internet search to find one. I adopt a loggerhead sea turtle nest annually through the Coastal Discovery Museum on Hilton Head Island. For my donation, I receive a certificate, a car sticker, and regular email updates about the general nesting season, and information about the specific nest I’ve sponsored. The funds support their educational programs “which inspire people to care for the Lowcountry and all the plants, animals, and people who call this place home.”11

SeaWorld Then
The first SeaWorld opened in 1964 in San Diego. SeaWorld Ohio followed in 1970 but closed in 2000. The Orlando park opened in 1973, and the San Antonio location in 1988. SeaWorld also has numerous affiliations with other parks, including Loro Parque in Tenerife, Canary Islands.

Shamu family name
Namu was the first performing orca at the Seattle Marine Aquarium. SeaWorld purchased an orca from the owner, Ted Griffin, and also purchased the rights to the name “Shamu,” a combination of “she” and “Namu.” Shamu became the first SeaWorld orca. SeaWorld used the names Shamu and Baby Shamu for marketing purposes and even took out copyrights and trademarks on those names. For decades, people thought that the orcas were the same few that SeaWorld began with in the late 1960s. This left the impression that “Shamu never dies,” as Erich Hoyt wrote.2 Other marine parks have used similar marketing techniques.
But the original Shamu had experienced the harpooning and death of her mother during their captures. Shamu bit three people during her captivity, sending at least one person to the hospital. The orca died four months after that incident in 1971 of septicemia at age nine.3 SeaWorld veterinarians had put her on progesterone to increase her fertility so that they could breed her. But instead, she contracted pyometra, a condition that causes serious infections in the uterus. “In the wild, her grandmother lived to be a hundred.”4 Despite her sad story, Shamu became the brand.
My parents visited SeaWorld Orlando between 1973 and 1976 and saw ‘Shamu’ perform, but it was actually Ramu. They took these photos:
Circumventing capture laws
In the 1970s, after the implementation of import laws and bans on whale and orca captures, marine parks began ‘transferring’ orcas from park to park to circumvent those laws. SeaWorld imported orcas on ‘breeding loans’ where no payment was involved, and they didn’t necessarily return the orcas. “According to researcher Ron Kastelein at Dolfinarium Harderwijk, ‘breeding loan’ is simply industry jargon which means that the first calf becomes the property of the acquiring institution and the second calf goes to the institution that provided the breeding-age male or female. Technically, the breeding animal remains the property of the first company.”5
Other times, marine parks relocated orcas multiple times until their origin was no longer able to be determined because documentation was ‘incomplete.’ Or, SeaWorld paid marine parks in other countries to acquire orcas, and then ‘transfer’ them a few months or even years later. This is often referred to as ‘warehousing’ and has been going since the late 1970s. “While orca care in captivity has improved measurably in the recent past, the industry still regularly engages in appalling practices like ‘whale laundering’ or warehousing orcas captured overseas (orcas are not legally available in U.S. waters) at a windowless backroom tank in another nation until sufficient times passes for it to be imported to a U.S. facility as a transfer, all so the American company doesn’t have to obtain a U.S. capture permit.”6

Captive Breeding vs. Conservation
The captive breeding programs at SeaWorld and other marine amusement parks were a direct result of bans on captures and the implementation of import laws. The parks had to find other ways to restock their orcas. However, this was the only purpose for captive breeding. “SeaWorld’s definition of ‘captive breeding,’ at least for orcas and bottlenose dolphins, is not the same as that used by the IUCN and other world conservation bodies – because the corporation apparently has no intention of re-introducing species to the wild,” wrote whale researcher, Erich Hoyt.7
In 2015 Joel Manby, the President and Chief Executive Officer of Sea World, said in a statement: “Depriving these social animals of the natural and fundamental right to reproduce is inhumane and we do not support this condition.”8But this was not simply by allowing orcas to mate. SeaWorld trainers artificially inseminate female orcas with the sperm from males also in captivity. SeaWorld’s breeding practices have been called inhumane and questionable by scientists and animal rights groups for decades.
In 2013, it was revealed that Tilikum was the father or grandfather of more than half of SeaWorld’s captive-born orcas. “Tilikum’s value to SeaWorld extends well beyond the raw market; he is, in fact, the cornerstone of the company’s captive-breeding program,” as David Neiwert wrote in 2015.9 Tilikum passed away in 2017 but it is believed that SeaWorld retained multiple samples of his frozen sperm to continue the practice.
“Rather than for conservation, captive cetaceans are bred merely to provide replacement animals for public display—an ongoing need given the high rate of mortality in captivity.”10
Orcas in captivity have a high infant mortality rate. Since 1980, three orcas died within 3 months of birth, and there have been 14 stillbirths and miscarriages. Those are just the documented ones. One sad example is Corky II at SeaWorld San Diego. She “had at least seven unsuccessful pregnancies before she achieved menopause and stopped cycling.”11

Makani’s mother, Kasatka, was an Icelandic orca, her father was the captive Argentinian orca Kshamenk from Mundo Marino. This is a prime example of the interbreeding of orca ecospecies through artificial insemination at SeaWorld and other marine amusement parks.
Mother-Calf Separations
As I wrote about in Part 2 of my orca series, many wild orca offspring stay with their mother and her familial pod for life. Grandmothers and mothers pass on knowledge about everything, including pregnancy, birthing, and raising their own. These skills are lost in captivity because Seaworld separates mothers and calves at a very young age and the young orcas don’t have a chance to learn. They also impregnate the animals at a much younger age than orcas would breed in the wild. These factors lead to high levels of infant mortality.12
“Captive breeding – often cited as a key reason for keeping animals in captivity – is an important part of conservation for some species and there have been notable successes at some zoos…But just keeping an animal in captivity is hardly conservation. In the artificial conditions of a zoo or marine park, an animal cannot continue its evolutionary path. The true measure of success is returning the animal to the wild.”13
“Education”
Many have already documented the lack of education in SeaWorld’s programming and educational materials. SeaWorld trained employees with inaccurate information about lifespan, diet, and environment that they relayed to the public. The company coached employees to circumvent tough questions from inquisitive visitors. They trained them to use semantics to defuse arguments against captivity. For example, orcas exhibit ‘behaviors’ instead of ‘tricks’. “SeaWorld orcas do not live in ‘cages’ or ‘tanks’ in ‘captivity’ and were never ‘captured’ from the ‘wild’; instead, they live in an ‘enclosure’ in a ‘controlled environment’, having been ‘acquired’ from the ‘natural environment.'”14 Recordings of SeaWorld trainers spouting inaccurate information are featured in almost all films about orca captivity.

Incidents
There were many incidents over the decades at SeaWorld. In 2006, the Occupational Safety and Health Administration (OSHA), whose role is to protect employees, investigated SeaWorld after an incident involving a trainer named Ken Peters. He was taken more than 30 feet down by an orca, suffering injuries and almost drowning. OSHA concluded in 2006 that “‘swimming with captive orcas is inherently dangerous and if someone hasn’t been killed already it is only a matter of time before it does happen.’ This of course turned out to be prophetic, as two trainers were killed by orcas within four years of the state agency issuing this statement.”15
But that incident did not come out publicly until after Dawn Brancheau’s death in 2010, during another OSHA investigation. The footage of the Ken Peters incident was shown at trial in full and leaked to the press (and you can find it online today).
Death
Since the advent of using captive orca for performance, there have been countless trainer injuries and several deaths. In December 2009, an orca named Keto killed Alexis Martínez at Loro Parque. Just a few months later, in February 2010, Tilikum killed Dawn Brancheau. Even more shocking, she was the third person known to have been killed by Tilikum during his captive history. SeaWorld blamed Brancheau for her own death, not once, or even twice – but multiple times. They have since gone back on those statements. But blaming the victim is reprehensible.
After Brancheau’s death, OSHA again investigated and “cited SeaWorld for subjecting employees to a workplace that contained “recognized hazards that were causing or likely to cause death or physical harm to employees” and they were fined the maximum. The long-term result of their unfortunate deaths was that OSHA banned “waterwork,” meaning that trainers can no longer perform in the water or swim with the whales. This was a massive change in the attraction’s main stage. You can learn more about the incident and the OSHA cases in the resources I’ve listed below.
As for the orcas, about 40 have died in SeaWorld parks alone. They could have prevented many of these.
The Blackfish Effect
Businesses like Southwest Airlines and top musicians severed ties to SeaWorld after Blackfish and David Kirby’s book both came out in 2013. Former senior trainer John Hargrove published his book shortly thereafter. The exposure created controversy over the issue of marine mammal captivity that has lasted almost a decade and is sometimes referred to as The Blackfish Effect. SeaWorld’s annual attendance decreased and their shares fell, and it seems that they have never fully recovered.

SeaWorld Now
In 1992, Erich Hoyt wrote: “SeaWorld has borrowed liberally from the wild to fashion its corporate image and to make its millions. Will it one day return something important by restoring an endangered cetacean to its natural habitat?”16 Almost 30 years later, we are still asking the same question. So what is SeaWorld doing today?
While SeaWorld initially resisted the changing views of the public, they have begun embracing those new perspectives. Next, I’ll explain SeaWorld’s changes over the last decade and explore what they are doing today. Thank you for reading, please share and subscribe!

The marine amusement park industry is thriving on the eastern side of the world, due to economic growth and an expanding middle class stimulating the entertainment industry. This means cetacean captivity has also increased in countries such as Russia, China, and Japan. As I mentioned in a previous article, wild captures of orcas have been outlawed or restricted in many parts of the world. However, the growth in marine amusement parks coupled with an absence of restrictions has led to a renewed increased in wild cetacean captures. It has also, unfortunately, prompted the creation of breeding programs in the eastern world, just when the western side is finally addressing the end of such practices.
“I foresee SeaWorld expanding overseas, where it would no longer be beholden to pressure from US legislators and public opinion. The premise of the company – to make money off the façade of conservation – has not changed from the 1960s and 1970s. And, if Americans learn to see through the terminology – ‘conservation through education’; ‘raising awareness for the species’; ‘in the care of man’ – then there will be fresh audiences overseas who may still buy into the mythology.” -John Hargrove, former SeaWorld senior trainer1

The Potential For Endangering Populations
Russian fishermen can catch belugas and orcas with a permit for ‘science and education’ under an allowable quota. But some believe that Russian orcas, which can sell for millions of dollars, are caught illegally and exported to China.2According to the Far East Russia Orca Project (FEROP), in 2012, an industry for captive marine mammals started up in the Russian Okhotsk Sea. Since then, whale hunters have caught and sold at least 29 orcas to four marine facilities in China and Russia.3
Orcas in those areas are transients and are thought to have smaller populations than resident killer whales. This renewed whale hunting could quickly move these animals toward extinction in the wild.4 But it is unknown exactly how many transient orcas reside in the Okhotsk Sea, so it is impossible to measure the potential long-term effect of these captures.5
“China’s marine park industry got started only about ten years ago…whereas people in the West have been familiar with marine entertainment for decades.”6

China
In China alone in the last five years, about 30 new marine amusement parks and dolphinariums have opened. This brings the country’s total to over 80 parks. There are plans to open approximately another 25 parks. The China Cetacean Alliance estimates that combined, these facilities have at least 1,000 cetaceans in captivity,7 and most were wild captures imported primarily from Japan and Russia.8 China also has no federal animal welfare laws.
“China appears to be immune to the ‘Blackfish effect,’ the term often used to describe the public’s response to the film…Chimelong [Ocean Kingdom] has paved the way for more orca breeding in China.”9
Chimelong Ocean Kingdom in China
This park opened in 2014 and is often referred to as the world’s largest aquarium. It is part of a larger tourist resort that mimics Orlando, Florida. They currently hold at least 9 captive orcas, but they may have additional whales that are not publicly displayed. The park began a breeding program in 2017, a year after SeaWorld announced they would end their captive orca breeding program.10 This park attracted more than 10 million visitors in 2018, so the business is thriving.

Moskvarium, Moscow, Russia
This facility opened in 2015 and has three captive killer whales performing in daily shows. When it was under construction, Erich Hoyt of FEROP said that it appeared that they were “enamored with the SeaWorld approach so I would expect loud music, the usual jumping through hoops and other circus-type routines,” as well as a breeding program like SeaWorld’s.11 If you look at videos online from people who’ve attended, it is exactly what Hoyt described.
Their website also shows that their focus is on entertainment, with learning as an afterthought: “Here you can spend all day: take a walk around the Aquarium, see a fantastic water show, have a bite at one of the many cafes and restaurants. Besides, it is not only a good place to entertain yourself, but also to gain some knowledge and experience in scientific work with unique opportunities to study marine biodiversity.”12

“Marine parks and shows make great attractions. Enamored and awed by the creatures, most people fail to realize the animals’ plight. In the news, training facilities are portrayed as caring institutions, marine mammals as happy, and their arrivals as celebratory events.”13
The Future
In 2018, the infamous Russian “whale jail” made worldwide headlines. Whale hunters illegally captured around 11 orcas and 87 belugas and held them in a series of small cells in Sreadnyaya Bay near Vladivostok. Fortunately, by 2020, the captors eventually released most of these animals but only after intense activism, investigations, and legal proceedings.14 But there are marine amusement parks in Russia, Japan, and China that are still seeking orca and beluga stock. This is what perpetuates these captures and places a high monetary value on their lives.
If you want additional information about captive orcas worldwide, Inherently Wild maintains a page on its website listing all known captured orca.15
How do we stop this practice worldwide? Is it through education, legislation, or activism? I don’t know the answer. But I do know that it took a combination of the three in the United States just to get minimal improvements on marine mammal captivity. But we still aren’t anywhere near where we need to be. My hope is that people worldwide will continue to learn about and value the natural world. Thanks for reading, please share and subscribe!

For as long as there have been stories and records about it, whale hunting has always been brutal, barbaric, and gory. Capturing orcas and other marine mammals for sale to aquariums and amusement parks is just as violent and brutal. Whale hunters have used explosives, helicopters, and other fear tactics to separate orcas from their pod. Many orcas have been killed accidentally in the process. Even more reprehensible was the cover-up of those deaths. Whale hunters posthumously cut open dead orcas and stuffed them with rocks to sink their bodies. Additionally, these captures in the 1960s and 1970s greatly reduced the populations of orcas, particularly the Southern Resident orcas.
At least 166 orcas have been taken into captivity from the wild since 1961, and 129 of these orcas are now dead.1 Eventually, laws ended these practices and captures. But this directly led to the establishment of breeding programs at SeaWorld and other marine amusement parks.

Whale Capture
“Most cetacean capture methods are extremely traumatizing, involving high-speed boat chases and capture teams violently wrestling animals into submission before hauling them onto a boat in a sling and then dumping them into shallow temporary holding tanks or pens.”2
The Vancouver Aquarium
In 1964, the Vancouver Aquarium captured an orca named Moby Doll, a male that they first believed was female. Originally, the aquarium had no intention of capturing an orca. They actually commissioned an artist to kill an orca to use as a body model for a killer whale sculpture. However, after harpooning a young whale and then shooting it several times, the whale did not die. Instead, the orca followed its captors as if on a leash for 16 hours in order to avoid the pain of resistance with the harpoon in his back. The aquarium put Moby Doll on display for scientists and the public to view. He did not eat for 55 days. When he started eating finally, he consumed 200 pounds of fish per day. But he never fully recovered and died after 87 total days of captivity.
“Moby Doll was the first orca ever held in captivity, and his amazing qualities, seen by humans for only those hard last months of his life, started both a new appreciation for orcas and a new industry of catching and displaying the whales for entertainment.”3
The Vancouver Aquarium no longer keeps captive whales. “After Moby Doll, [they] got more orcas and kept at least one in captivity until 2001, when its last orca, an Icelandic whale nicknamed ‘Bjossa,’ was shipped away to SeaWorld in San Diego, where she soon died.”4
Seattle Marine Aquarium at Pier 56
In 1965, Fishermen accidentally caught Namu the orca in their net in Canadian waters. Namu was the first captive performing killer whale. They contacted the owner of the Seattle Marine Aquarium, Ted Griffin, who bought Namu for $8,000. Griffin put him on display. “Crowds flocked to Pier 56 to watch Griffin ride the whale and to see Namu jump on command,” according to The Seattle Times.5 Downtown shops sold Namu souvenirs. There are two songs and a film about Namu.6
“Within a month, Griffin made history, becoming the first human ever known to ride a killer whale…Visitors and the press were crazy for the story of Griffin and Namu.”7
Griffin intended to capture another whale so that Namu would have a mate. Activists and scientists protested. Then two female whales died during Griffin’s effort, which exacerbated the issue. In the midst of that, Griffin received approval to build a new marine park as a new home for Namu. But the project never came to be.8

Namu’s legacy
The success of the aquarium from having Namu “spark[ed] a period of orca captures in the region, when a generation of southern resident killer whales was taken and shipped to aquariums around the world.”9 Other marine amusement parks sought the financial success of having captive performing orcas. Unfortunately, it became an established practice.
“Namu fever stoked an international craze for killer whales to put on exhibit all over the nation and the world. Captors particularly targeted the young, the cheapest to ship.”10
Sadly, Namu died within one year. He drowned after he became entangled in the netting of his pen. The autopsy revealed a massive bacterial infection caused by the raw sewage polluting the bay,11 and this likely contributed to the whale’s disorientation and drowning.12
Ted Griffin continued pursuing orcas and was part of the famous Penn Cove massacre in August 1970 when four orcas were drowned in their nets. In a failed effort to cover up the deaths, Griffin ordered workers to cut the whales open and weigh them down with chains and rocks to sink them. But the corpses were caught in a fisherman’s net and hauled to shore a few months later, and news reporters captured the event. “Griffin lost the stomach for orca captures after the Penn Cove debacle and dropped out after 1972.”13

“Every one of the fifty Southern Resident whales captured by Ted Griffin and Don Goldsberry from the Puget Sound is now dead, with one exception…Lolita.” -David Neiwert14
The Marine Mammal Protection Act in 1972
In the 1960s and early 1970s, whale captures were largely unregulated and were completely legal. Humans captured hundreds of orcas and thousands of marine mammals during those decades for all types of purposes. Congress passed the Marine Mammal Protection Act in 1972 (MMPA) in direct response to concerns about the effects of human activity on marine mammals. But at the insistence of the theme park industry, Congress gave an exemption for marine mammals in zoos and aquariums, under the facade of ‘for educational purposes.’15 Conservation was the term used to claim these exemptions.
“When drafting the Marine Mammal Protection Act of 1972 (MMPA), members of the US Congress believed, or were lobbied into promoting, the long-accepted view that the public display of wildlife (at facilities such as zoos and aquaria) serves a necessary educational and conservation purpose.”16
The National Oceanic and Atmospheric Administration (NOAA) granted SeaWorld an economic-hardship exemption in 1974. This allowed them to continue the practice of hunting orcas.17 All of this affected the Southern Resident populations.
NOAA grants other exceptions under the MMPA. Examples include scientific research, photography, capture, or first-time imports for public display in aquariums, or rescues.

Washington State
In 1975, Washington State filed a lawsuit against SeaWorld and in 1976, closed its waters to killer whale captures, a direct reaction to the ridiculous craze for capturing them. “By 1976 some 270 orcas were captured — many multiple times — in the Salish Sea, the transboundary waters between the U.S. and Canada, according to historian Jason Colby at the University of Victoria. At least 12 of those orcas died during capture, and more than 50, mostly Puget Sound’s critically endangered southern residents, were kept for captive display. All are dead by now but one,” referring to Lolita at the Miami Seaquarium.18 Southern Resident orcas lost a third of their population to capture by 1975 and the ecotype has never fully recovered. “Nearly a whole generation of reproduction was represented in the whales captured and killed,” wrote David Neiwert.19 The Southern Residents were classified as endangered in 2005.
Icelandic and North Atlantic captures
Less than 8 months later, SeaWorld and other marine parks moved their capture operations to Icelandic and North Atlantic waters. SeaWorld hired Don Goldsberry, who had been a part of the Puget Sound massacre, to go to those areas.20 “Between 1976 and 1989, at least 54 orcas were captured from Icelandic waters and sold to marine parks around the world. [Seventeen] of those whales ended up at SeaWorld parks.”21 Forty-eight of these orcas have died in captivity.22 Killer whale capture in Iceland ended in 1989 (but whale hunting, in general, began again in 2003).
Tilikum was one of the wild captures from Iceland and the North Atlantic.23 Tilikum was the whale who killed his trainer in 2010 at SeaWorld Orlando and may have been responsible for two other human deaths during his captive history. He passed away in 2017. Whale hunters captured Keiko, the star of Free Willy, from the same area. Kiska, whom I wrote about previously, was also captured there.

After 1989
Laws prohibiting wild captures led to the establishment of captive breeding programs at marine amusement parks. Over the last 40 years, this practice has become the new standard for replenishing orca stock. “One of the keys to SeaWorld’s success was its ability to move away from controversial wild orca captures to captive births in its marine parks. The first captive birth that produced a surviving calf took place at SeaWorld Orlando in 1985. Since then, SeaWorld has relied mostly on captive breeding to stock its parks with killer whales, even mastering the art of artificial insemination.”25
Thankfully, the practice of captive breeding is now ending in the western world. But in other parts of the world, marine amusement parks are growing in popularity. This means wild captures are now on the rise in those areas. In my next article, I’ll share some of this information with you. Thanks for reading, and please share and subscribe!
