Just ten days after Valentine’s Day in 2010, a captive SeaWorld orca whale named Tilikum brutally drowned a forty-year-old veteran trainer named Dawn Brancheau during a live show performance. In one quick motion, Tilikum grabbed onto Brancheau’s arm and dragged her into the million gallon tank. With a blood-curdling scream, Dawn was dragged to the bottom of the tank and tossed around. In the autopsy report, Brancheau suffered an enormous amount of blunt force trauma due to the massive force of the twelve thousand pound animal slamming on top of her. The violent attack even scalped a layer of Dawn’s head right off. Yet, it was noted that the cause of death was drowning with “approximately four milliliters of fluid in her sphenoid sinus” (Autopsy …show more content…
As marine biologist Naomi Rose stated, “Captive orcas routinely show damaged dentition, primarily broken and worn teeth with the pulp exposed. This is in contrast to wild orcas: many show little or no tooth wear while those who do tend to specialize in prey with abrasive morphology. Broken teeth in wild orcas are rare” (6). Due to the strain and dullness of being locked in cages, the orca whales gnaw away at the gates which wears their teeth down and causes further infection. This is unlike the orcas in the wild, who do not have many dental problems. The orca whales’ poor dental health induced by self-harming techniques imposed by boredom and stress increases their rate of lethal infection and death. By keeping whales in captivity, the lifespan and health of whales deteriorates. In Death At SeaWorld: Shamu and The Dark Side of Killer Whales in Captivity, studies by Mike Bigg and colleagues “showed wild female orcas with an average lifespan of 50.2 years and males with 29.2 years” (Kirby 181). However, the lifespan of a captive orca whale is far less. Erich Hoyt stated that at the time, “Only one male in captivity has even reached this average” (Kirby 181). This further proves that the lifespan of orcas is slowly decreasing in captivity than in the wild. In allowing orca whales to live in captivity, places like SeaWorld deprive orca whales of a long healthy life to that in the wild. It deprives the beautifully intelligent creatures of a life filled without pain and

...Orca captors and their supporters argue that captive orcas receive adequate physical and mental stimulation, allowing the orcas to be content and healthy in their habitats. To support these claims, SeaWorld’s website states: “Our whales show every sign of physical fitness including healthy weight, muscle tone, respiratory efficiency, strength and heart rate. While our whales do not live the same lifestyle as their wild counterparts, this difference does not translate to negative welfare of these animals” (SeaWorld 1) Many visitors witness the captive orcas interacting with trainers and performing tricks and feel as though the orcas live active and healthy lives. They believe that captive orcas are as content as their wild counterparts, despite...

...Orcas are kept in captivity their whole life. They are captured with big nets and bombs that are thrown into the water to make the parents abandon their young and allow the capturing of the baby orcas easier. when orcas are young around 2 or 3 years old they are taken from their mother’s side. Orcas should not be kept in captivity because their life expectancy decreases, they are treated poorly and leads them to becoming more aggressive. Instead of supporting orca captivity people should stop attending the orcas water show at seaworld so they are released back into their natural habitat the wild. From the time, they are captured at 2 years of age until they grow into their 20s and die the orcas live in a pool that is very small. Adults should not...

One orca, named Shamu, was captured and watched her mother die. SeaWorld of Hurt states, “During Shamu’s capture, her mother was shot with a harpoon and killed before the young orca’s very eyes by a marine ‘cowboy’ named Ted Griffin.” Many orcas at SeaWorld were taken from their homes. SeaWorld of Hurt also states, “Five orcas currently at SeaWorld were kidnapped from their ocean homes, as others who have since died. For example, Tilikum… was captured at the age...

Orca Captivity

...Killer whales, known as orcas, are the top predator in their ecosystem. Their beauty and intellectualism has thrilled humans for ages, but for many orcas in captivity limits their freedom of the ocean. People still profit from these killer whales regardless of the harm to the Orcas or to the people. The use of these marine animals in parks needs to be diminished because it damages the mental and physical health of these animals, as well as threatens the lives of the trainers. In the ocean whales can travel many miles, however in captivity the tank is only twice their size. Due to the tank size it can cause physical and mental stress to these Orcas. Out in the wild they have a free range to swim. If they are in a small tank, especially if with other orcas they are more likely to show aggressive behavior. This aggressive behavior can lead one orca to hurt another orca, leading them to need treatment from the injuries. Many people may argue that they can get the special treatment they need in these parks, but don’t realize that they have a less chance of injury out in...

SeaWorld shouldn’t be able to have whales and dolphins in their parks because it hurts the life expectancy of the animals, the peoples safety is in danger, and the health of the animal can be affected greatly. The life expectancy of orcas in captivity is nowhere near the wild life expectancy. The life expectancy for an orca is very low compared to in the wild (wild male, about 30; female, about 50). The orcas are losing their lifetime in captivity as for orcas in the wild are trying to live life to the fullest. Out of 160 whales that died in captivity,...

Whales that are kept in captivity have a greater risk for medical and emotional problems. Orcas kept in captivity have a higher amount of social anxiety compared to orcas in the wild. Whales should be banned from public entertainment because it causes the whales to have greater amounts of problems compared to those in the wild. Health and emotional risks generally occur more in whales who are kept in captivity.Whales whom are kept in captivity have higher emotional struggle, which causes the whales to go insane because of this whales have killed three trainers at Seaworld (Whales and Dolphin Conservation) This proves that whales who are kept in captivity have a greater emotional problems than they do in the wild.

...Free Orcas How much do you really know about whales in captivity? Do you think the whales at sea world enjoy being there? Imagine you're walking down the street with your family when out of nowhere you're trapped in a net and being taken away from them. This happens to young whales almost everyday and is very unnecessary. Orcas should not be kept in captivity because it causes premature death, anxiety, and violent behavior. Many people would consider these results to be animal abuse. It has been confirmed that whales in captivity have higher mortality rates than those in the wild and these rates have only worsened over the years. According to the report “Killer Controversy: Why Orcas Should No Longer Be Kept in Captivity,” "Captive female orcas give birth too young and too often, leading to both high adult and high infant mortality." Also, the chronic stress of being confined weakens their immune system which leads to infection. This is the most common cause of death for captive orcas. The average life expectancy of a wild orca is 30-50 years. Orcas who have died at Sea World have an average age of death of 13 years old. The shocking fact is that over 161 whales have died in captivity, and it can easily be prevented by leaving them in the wild where they belong. Another outcome of the confinement is anxiety. Orcas who are not compatible with one another are placed in relatively small tanks which results in anxiety and tension. This tension often leads to brutal fights...

...Dolphins Belong to the Wild-- Captivity Harms Them The essay “Orca Encounters” discusses how much humans can help the orcas when they are separated from their family and arrive at our coasts. Should we send them back their pods, or just let them interact with humans? In the text, some experts believe it’s better to let the orcas stay, because the social interaction that the orcas are seeking can be made up by humans, so they may not be interested in returning back. Many other experts believe that the solitary orcas belong to their family, and it’s improper to keep them from returning. Also, the text mentions more scientists agree that “any reunion of wayward cetacean with its pod should happen quickly”(Groc 162). However, there isn’t an example of other cetaceans, and the text doesn’t give any detailed information about what scientists have studied to reach the agreement above. For instance, solitary dolphins are even more common to see than solitary orcas, and many of them have been captured because their kindness and cleverness make people keep them, even though many studies show captivity does harm to the dolphins. Fitness of the dolphins is influenced the most during captivity. As the environment has changed after being captured, dolphins’ emotions have also changed. “[The captivity of dolphins] causes desperation because their basic instincts are obstructed, obviating millions of years of ingrained behavior”(Rivera). Rivera states that mother dolphins take care of...

...whales; also known as the orca, (Orcinus orca) first to put in a cage for the world to see. The view of the killer whale has shifted from a dangerous killer to a cuddly animal. Theses whales have gone from a sea creature shot at by humans, to the star money maker at theme parks. Both images become one-sided, putting the creature into stereotypes. Orcas resemble humans, very complex, intelligent, and also taken advantage of. As of today, they stand as the largest animal and predator to be put in the smallest captivity. The killer whales beauty has mesmerized humans for years, but captivity not only breaks down the physical and mental health of these creatures, and also puts others in danger. Studies have shown the life expectancies of an orca in captivity remain well below the life of a wild counterparts. Industries claim that the achievements in veterinary care and nutrition have made a life of orca far better, but studies prove that the whales act much better in the wild. In 2007, SeaWorld responded to questions asked by KGTV and stated “We have often said that 30 years is a good estimate of average killer whale lifespan as we can exceed that age, as evidence by one of ours, Corky. She is at least 40 and perhaps as old as 42. Biology of Marine Mammals said that female killer whales in their studies group had a mean life expectancy of 31 years and males just 19 years”(Rose). The average whale can live up to 100 years old in the wild. In captivity the average whales life will...

...The capturing of orca whales for entertaining and performing purposes originated in 1964 when the first SeaWorld park was opened in San Diego, California. The exploitation of these animals in amusement parks quickly grew into a widespread phenomenon in the United States. America quickly fell in love with “Shamu”, the Killer Whale that became the face of Sea World. These wild creatures live their entire lives in captivity. In order to take a stand, parks like SeaWorld need to be shut down and forced to release their orcas into the wild, where they can live freely the way they were intend to. When orca whales are held in an unnatural environment for their entire lives, it causes a variety of problems for them. The wild animals become increasingly aggressive, suffer health issues and are ripped away from their families in the ocean....

Zoos and aquariums cause many problems for animals: mental issues, propagation, confined spaces, and families being torn apart. However, zoos and aquariums say education is provided along with helping endangered animals. One reason animal captivity should be banned is animals suffer both mentally and physically. The different environment causes issues for example, orcas and dolphins use echolocation; but, the tank causes the reverberations to bounce off and hit the cetacean which results in frustration and mental issues...
