After i found this video i did some research about behavour of Orca's ( killer whales )
in captivity and found this.
" Captive orcas also display aggression towards each other, as well as self-destructive
behavior. Rake marks and injuries inflicted are often observed on captive orcas, while it
is also well-documented that captive marine mammals engage in harmful stereotypic behaviors
such as gnawing on tank walls or gates."
" Captive life is stressful due to small tanks, false social groupings, increases disease
potential, isolation and chemically altered water. To relieve their stress, captive killer
whales may get aggressive toward themselves, other killer whales, or humans."
" Water pressure and travelling long distances in the wild keeps tissues in the dorsal fin
healthy and so the fin upright. Lack of space and spending so much time on the surface of the
water causes fin collapse in captive whales. Dehydration and unnatural diet could also contribute."
" Boredom: Daily monotony and lack of appropriate challenges in such a large-brained complex animal,
lead to immobility (increased logging behavior on the surface), depression, irritability and increased anxiety."
"Captive orcas exhibit a range of abnormal behaviors, inter alia hyperaggression, stereotypies, self-harming,
rejection of offspring, and failure to nurse, which may contribute to morbidity and mortality."
What SeaWorld Won’t Tell You About Dawn Brancheau’s Death
SeaWorld trainer Dawn Brancheau began her Dine With Shamu show on February 24, 2010, just as she had
many times before, but this particular show included a gruesome finale that left Brancheau’s body without
her left arm or part of her scalp, among other injuries. Dawn Brancheau was declared dead shortly after
the show, but still, 11 years later, SeaWorld claims no responsibility for the vicious attack. So just how
did one of SeaWorld’s most experienced and celebrated trainers end up crushed and drowned by the jaws of the
marine park’s largest attraction?
“We don’t know for sure what motivated Tilikum. But there’s no doubt that he knew exactly what he was doing. He killed her.”
—Former SeaWorld Trainer Jeffrey Ventre
A Killer Whale Is Born
Former SeaWorld trainer Jeffrey Ventre blamed Tilikum for Brancheau’s death, but the truth begins with the wild
orca’s capture near Iceland in 1983. At just 2 years old, he was torn from his mother and their ocean home and
sent to the rundown marine park Sealand of the Pacific. Food was withheld from him as a training technique, and
he endured attacks from the two dominant female orcas, whom he was forced to live with. After years of performing
eight shows a day, seven days a week, Tilikum dragged Sealand trainer Keltie Byrne to the bottom of the pool, where
he and the other orcas stripped her of all her clothing and left bite marks and bruises on her skin. It took nearly
two hours to retrieve her body. Not long after Keltie’s death, Sealand closed its doors, and its orcas were purchased

“My understanding of the animal’s past was very limited. In fact, there had been 30 incidents between killer whales,
and trainers prior to my being hired at the park. And I didn’t know about any of them until after I left SeaWorld. So I think
that’s a serious mistake on SeaWorld’s part that they weren’t letting people know the history of all the animals.”
—Former SeaWorld Trainer Samantha Berg
History Repeats Itself
As Dawn Brancheau lay next to Tilikum, petting him in just a few inches of water, she likely had no reason to suspect that
she was about to be torn apart. According to one of SeaWorld’s own employees, the event was unpredictable and the orca gave
no indication that he was about to grab her. Even if Brancheau had spotted signs that Tilikum might act aggressively, would
SeaWorld’s star performer have done anything differently? Maybe not—trainers were expected to continue performances, regardless
of any signs that an orca might act out.

Dawn Brancheau was one of SeaWorld’s star performers. She was cautious and always abided by the park’s “safety” guidelines when she
was around the orcas. When her death was announced, former and current trainers were astonished that she had been the one killed.
In one case, trainers ended a show after an orca began to ignore signals, swim rapidly, and grab at one of the trainer’s arms.
In response, SeaWorld’s vice president for animal training criticized their actions in a two-page document claiming that the show
should not have been ended early because it brought unnecessary attention to the incident. He argued that the trainers should have
used other resources before canceling the show, despite SeaWorld’s official position that trainers could end a show at any time if
they felt uncomfortable.
Why were SeaWorld trainers being forced to interact so closely with these enormous wild mammals? This was precisely the issue at the
center of the Occupational Safety and Health Administration’s (OSHA) investigation. The agency cited SeaWorld for multiple violations
and demanded that the company stop putting trainers at risk by making them interact with orcas during shows.
The Truth Comes Out
SeaWorld finally gave up on appealing its violations, but not before OSHA presented damning evidence that seems to imply that SeaWorld may
be responsible for its own trainer’s death. OSHA found that in the 20 years leading up to Brancheau’s death, the park generated 100 reports
of aggression and precursors to aggression—including 12 incidents resulting in the injury or death of a trainer—and according to SeaWorld’s
own corporate curator for zoological operations, there were times that the company didn’t document incidents at all, which can be evidenced by
SeaWorld’s failure to generate an incident report for Dawn Brancheau’s death and for a third death that Tilikum may have previously been involved with.

SeaWorld had previously been warned of the potential danger of incorporating Tilikum into its marine park when obtaining a permit for the orca
from the National Marine Fisheries Service (NMFS), long before Dawn Brancheau’s death. Upon applying for the permit, SeaWorld hadn’t even looked
at the incident report about the Sealand trainer’s death, and after being urged by the NMFS to do so, SeaWorld attributed the previous attack to
a design flaw at Sealand. SeaWorld reiterated multiple times while obtaining the license that its safety measures, training, and park facilities
were superior to those of Sealand and would prevent such an event from occurring at its park.

Tilikum, one of the largest orcas held captive at SeaWorld, was in captivity for over 30 years. His sperm was used to father over half the orcas at
SeaWorld’s parks, even though he killed three humans.
Eleven years after the “accident,” there are still concerns about Dawn Brancheau’s last day as a SeaWorld trainer that have grave implications.
Why did the marine park wait for 27 minutes to call for paramedics after Tilikum pulled Brancheau into the water? Was the park using this time to
remove witnesses whose accounts didn’t match the story that SeaWorld was trying to create to make it seem as if her ponytail had triggered Tilikum’s reaction?
Perhaps most importantly, why did SeaWorld’s then-owner try to blame his own orca trainer for her death—even after the OSHA investigation uncovered
that the same safety measures and recall signals that had failed to prevent Dawn Brancheau’s death had been failing for years? And why did SeaWorld
continue to rely on those failed measures?
“Let’s face it, in these types of incidents, I don’t recall any whale responding to any hand slap, food bucket, or any other distraction we tried to implement.”
—Internal SeaWorld document
The evidence in the judge’s decision seems to indicate that SeaWorld tried to downplay the risks and dangers that its trainers would encounter while
working with captive orcas and to cover up its own failures in the incident that led to Dawn Brancheau’s death. SeaWorld wasn’t even willing to put the
life of its own star trainer before profit, so why should anyone trust that it would ever put the well-being of its captive animals first?
