Orcinus orcas, or more commonly referred to as killer whales are one of the world’s most dominant predators and largest of their dolphin kind. Killer whales are single celled organisms that belong to the Eukarya domain. The eukarya domain consists of four kingdoms: Protista, Fungi, Plantae, and Animalia. Killer whales belong to the animalia kingdom, which consists of multicellular animal organisms composed of eukaryotic cells that lack cell walls. Ranking below kingdom is the category phylum. Killer whales belong to the phylum chordata that includes vertebrates. After phylum comes class on the hierarchical system. Killer Whales are mammals so they are a part of the Mammalia class. The Mammalia class is followed by order; there are nineteen orders of mammals. One of these nineteen orders is order cetacea. Cetaceans include whales, porpoises, and dolphins. Killer whales in fact belong to the delphinidae family other wise known as dolphins. The delphinidae family of cetaceans is extremely diverse, ranging in size and weight the species belonging to the delphinidae family have many variations between them. The scientific name of the species of the Killer whale as mentioned earlier is Orcinus orca. Orcinus is the genus of the Killer whale and Orca is the species. A killer whales appearance is very unique from other whale species and other species in its respective delphinidae family. A Newborn killer whales range anywhere between 2.1 to 2.5 meters, which is equivalent to about 7 to 8.5 feet. Adult killer whales measure between approximately 5.5 to 9.8 meters, which is equivalent to 18 to 32.25 feet. The size of a killer whale varies between male and female killer whale. Males tend to be lengthier in size compared to females. Averaging at a length of about 7.4 meters (24ft) males can grow up to roughly 9.7 meters (32ft). Females; however, measure up to be much smaller in…...

...aggressive" orca who has been linked to the deaths of three individuals while being kept in captivity. The film, told largely by five former SeaWorld trainers, uses highly emotional footage to portray Tilikum as an animal that has been negatively impacted by his life at SeaWorld. Blackfish is advertised as a documentary but, in reality, is little more than propaganda, and rather than providing impartial and balanced information, the film uses inaccurate and deceptive facts in a clear example of how bias is used in the media to portray a certain view to the audience. The film misrepresents the orca species as a whole by saying that "they're amazingly friendly and understanding and intuitively want to be your companion." This implies that killer whales are naturally amicable and respectful to humans. Blackfish shows footage of an orca interacting with a dog to justify this statement, but does not explain that the orca shown in that video was an abandoned juvenile named Luna who had been living in Nootka Sound for five years, where he was constantly exposed to human presence and activity. The interactions with Luna that are shown in the film are not an accurate representation of the average, well-adjusted, pod-dwelling orca. This footage is shown out of context and makes the false claim that killer whales, as a whole, are more wary of human presence and generally keep to themselves in natural conditions to skew the viewer's opinion and understanding of normal orca behavior in...

...ORCA project: http://www.huffingtonpost.com/2012/11/10/mitt-romney-project-orca-broken-app-cost-thousands-votes_n_2109986.html One problem was that volunteers were instructed to look for a native mobile app when Orca was a web app, and the URL was listed as an HTTPS site, but the HTTP address didn't forward users to the right page, according to John Ekdahl, a Romney volunteer who detailed the problems with the app and called it an "unmitigated disaster." An anonymous campaign source on the Colorado team revealed to Breitbart.com that it received hundreds of calls from volunteers who couldn't use the app or the back-up phone system. He revealed that usernames and passwords were wrong, and the reset password tool didn't work either, which meant they couldn't change phone PINs. "The primary issue was we beta-tested in a different environment than [headquarters Boston Garden]," he told the website. "There was so much data coming in -- 1,200 records or more per minute -- it shut down the system for a time. Users were frustrated by lag, and some people dropped off and we experienced attrition as a result." Working primarily as a web developer, I had some serious questions. Things like "Has this been stress tested?", "Is there redundancy in place?" and "What steps have been taken to combat a coordinated DDOS attack or the like?", among others. These types of questions were brushed aside (truth be told, they never took one of my questions). They assured us that the system had......

Orcas

...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......

...ponytail and drag her into the water with him. It took the other trainers 45 minutes to extricate Brancheau’s body, which Tilikum held in his mouth and would not let go. All the trainers in Sea World, located in Orlando, Florida, as well as other locations throughout the United States, agreed that Tilikum was well behaved, easy to work with and always eager to please. So what exactly made Tilikum act so violently and take the life of his trainer? There is a reason that there have been no documented deaths of humans by killer whales in the wild – it is obvious that being forced to live and perform in captivity is the reason behind it. It has been argued and scientifically proven that no human being has ever been killed by a killer whale, or orca, in the wild. On the other hand, there at least a dozen documented deaths due to killer whales throughout the world. The main reason this is said to be true is because killer whales, which can grow to be more than 30 feet long and weigh up to 6 tons, are not meant to be kept in tanks and modules that are 20 feet wide and 35 feet deep. These tight living confinements have been proven to cause certain psychoses in animals. (Allen & Flannery 2014) They are essentially giving up the whole ocean for a bathtub. Since Brancheau’s death in 2010, Tilikum has been kept out of the spotlight and has lived a very lonely life. The 2013 documentary, Blackfish, documents Tilikum’s journey since the day he was captured off the coast of Iceland in......

...evidence of the Orca whales being taken and abused within the “care” of SeaWorld. Her purpose for creating this film is to increase awareness of the captivity of the Orca whales and the effect it has on the whales and their trainers, also to inform the audience of how SeaWorld misleads the public about the captivity and care of the whales. Blackfish documents and exposes the treatment of Orca whales and their trainers as well as the secretive SeaWorld Corporation. Gabriela Cowperthwaite’s audience was mainly anyone who is concerned about this problem or just wanted to know more on what is really happening to the Orcas at SeaWorld. Her use of diction is how she targets her particular audience. She uses facts and evidence to support her argument; in this case she uses more sophisticated diction. However her whole argument and point are easy to understand. With her choice of persuasive diction she draws any audience as well, even someone who may not be as concerned or aware about this problem, her strong word choice makes it known to anyone that this is a problem. For example, a strong point she made was; “this is an artificial assembly of their collection not a family”. She states this because of false advertisement that SeaWorld presents to people, saying that the Orcas captured are one big family. The audience could be anyone of any age. In the documentary Gabriela Cowperthwaite argues that the Orcas are being mistreated in a way that is inhumane and that the Orca whales......

...Krista Jackson October 7th, 2014 College Credit English Cause and Effect Essay Black Fish Since 1964, killer 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......

A Review of Management Problems Arising from Reintroductions of Large Carnivores

...Duggins (1995) showed that the presence of sea otters (Enhydra lustris) depressed populations of sea urchins, which, in turn, allowed the proliferation of kelp forests, subsequently increasing biodiversity. In sites where otters were not present, kelp was significantly denuded or completely absent. Long term monitoring showed that, in areas where otters were introduced or where their range expanded, urchin biomass was reduced by between 50 and 100% and biodiversity increased. In contrast, in areas where otters were constantly present or absent, urchin biomass was unchanged. It should be noted though that trophic cascade effects are not always predictable or even desirable from a management perspective. For example, when killer whales (Orcinus orca) suddenly began to prey on the sea otters the numbers of urchins increased and kelp decreased (Estes, Tinker, Williams, & Doak, 1998). As apex predators, large carnivores often reproduce slowly, require relatively large home ranges, and occur at relatively low densities (Primack, 2006). This makes them vulnerable to changes within the ecosystem. Climate change, anthropogenic land use, and degradation or destruction of habitat have decreased biodiversity (Primack, 2006; Samways, 2005). Changes in land use coupled with climate change are predicted to have the largest influence on biodiversity between now and the end of this century (Sala et al., 2000). It is likely that many large carnivores will lack sufficient space and/or prey......

Tilikum the Killer Whale

...was withheld from him as a training technique, and he regularly endured painful attacks by two dominant female orcas, Haida and Nootka. He was forced to perform every hour on the hour, eight times a day, seven days a week. The constant stress and exhaustion gave him stomach ulcers. If that wasn’t enough he was then put into a tiny round metal-sided module with two other orcas for more than 14 hours until the park reopened the next morning. This is just enough to make a killer whale go insane. Tilikum was capture when he was two years old and for all of the things he’s been put through already for his age is not going to make him grow up as a regular Orca, I mean, no orcas that are held captivity are going to live a normal life. But being the fact that Tilikum is a larger whale, being held in captivity would be taken as a larger impact on him psychological and physically. So, since they would take away his food and get attacked by the two other orcas as training techniques, Tilikum became stress, frustration, and confinement. Which was stirring up an attack to happen sooner or later. On February 21, 1991, Sealand trainer Keltie Byrne fell into the pool containing all three orcas. She was pulled to the bottom of the enclosure by Tilikum, tossed around among the three orcas, and ultimately drowned. It took Sealand employees two hours to recover her body from the orcas. She was the first of three people to have been killed. After the death of Keltie, Sealand closed its doors......

...world's view of whales. He has killed three people. Tilikum is a male Orca, more commonly referred to as a killer whale, with a complex background. In 1983 Tilikum was violently captured in Iceland and then illegally sold to 'Sealand of the Pacific' aquarium in Canada. He was two years old when this happened, ripped away from his family and cruelly sent to foreign waters. In the wild, Tilikum was used to swimming over 100 miles every day; in 'Sealand of the Pacific' Tilikum was used to floating in a concrete prison only ten feet longer than his body. When Tilikum was not confined in these small spaces, he was taken into a pool where he would perform tricks for audiences in order for him to receive food. The food was frozen fish which deprived the Orca of his necessary nutrients and food was withheld from Tilikum if he did not respond to the trainers' instructions. Tilikum was a highly intelligent whale and due to this he seems to have noticed his mistreatment. Tilikum began to become restless, frustrated with being trapped in a concrete box and performing tricks for slivers of food. The trainers registered Tilikum's agitation but they did not see it as being significant. It was too late when Sealand of the Pacific finally realised that Tilikum's emotions were important. In February of 1991 a part-time trainer at Sealand fell into the pool whilst Tilikum was performing with two female Orcas. Tilikum, along with the other whales, began to drag Keltie Byrne......

...condition these orcas were living in, and the way they were being treated proves it all. From watching the film, they’re argument seems pretty much believable. The tear-jerking scenes really emphasized the purpose. Yes, Tilikum was the cause of Dawn Brancheau’s death, but what caused Tilikum to react this way? The documentary shows that many mistakes were made with orcas from the very beginning to cause the orcas to react with such aggression. The former trainers from Sea World had very close relationships with the orcas. The clips of how friendly and kind the orcas were supports the film makers’ claim. One of the former trainers said, “It was like a relationship he had never had.” I could feel the anger and ___ in the film makers’ tone by how they throw the blame on Sea World. Being that these whale are complex mammals with enhanced social skill, and are huge; small captivity is not the best way to get positive reactions out of them. The accommodations for the whales were unfit for a healthy life style. Most whales at Sea world began to have drooped dorsal fins. There many false facts given to the public about the killer whales: “More than twenty-five percent of all killer whales have drooped dorsal fins as the get older,” or “Killer whales actually live longer in Sea World’s environment because of veterinarian care.” All of that was utterly false. The trainers knew the truth. It was discovered in the 1980’s that orcas live......

...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......

Trapped Orcas

...killer whales (orcas) away from their families and home. Throughout the years this has caused damage to the orcas causing rebellion and other forms of defiance. There have been many incidents following the rebellion of these orcas and yet nothing is done about the issue. Sea World should not keep killer whales against their will or keep them captive. Orcas are sea creatures, meaning they belong in the ocean. So why is it that they ended up in large fish tanks held against their will? SeaWorld claims to people that killer whales are better off under their care (Black Fish). Indicating that by taking the orcas from their families, it is rescuing them and giving them better help. Stating that they took them to show others how caring and talented they can be. The park implies that people will learn a lot about life in the sea. Many think that if they come to the park, they are doing a good deed and will be educated on life in the ocean. The employees working on the tours are also obligated to say all these lies to the guests about the park. For instance, a commonly asked question is why some whales have their fins bent, in other words, have a dorsal fin collapse. The park answers to guests that it is normal, but in reality that is not supposed to happen and is caused by the tanks (Black Fish). Orcas were not meant to live in big tanks they were meant to live in the ocean with other orcas. People being misinformed on what is really going on to the orcas is a huge......
