Killer whales Essays

Killer whales, also known as “Orcas,” are the powerful rulers of the ocean. A male killer whale can be almost 33 feet in length, which is as big as a medium-sized bus. These colossal creatures were named “killer whales” by ancient sailors who saw them preying on large whales. Killer whales have a black top that is largely covered in white patches near the eyes and on the undersides. Behind the dorsal fin, they also have a gray or white saddle patch. They are commonly found in cold waters, such as

Killer whales were initially captured in the 1960s, when a female orca was captured and put into a tank. Two days into the female orca's stay she repeatedly bashed her head against her tank wall and perished the following day. Unfortunately, people did not heed or take any precautions from this traumatic incident and since then killer whales all over the world have been captured for entertainment purposes and have been stored in facilities such as SeaWorld. From these types of facilities incidents

particular stands out from the rest. Killer whales, also known as “Orcas,” are the powerful rulers of the ocean. A male killer whale can be almost 33 feet in length, which is as big as a medium-sized bus. These colossal creatures were named “killer whales” by ancient sailors who saw them preying on large whales. People think Killer Whales are just big animals in the sea, but there are more informations about them beyond that. Physical Descriptions Killer whales have a black top that is largely

at the age of only two (A Killer Whale Gone Very Bad). He would spend 14 long hours in an eight-meter-wide enclosure with two park female killer whales, who viciously bullied him (A Killer Whale Gone Very Bad). Now today, he spends most of his time alone, drifting lifelessly in a pool at Orlando’s Seaworld (A Killer Whale Gone Very Bad). Killer Whales in captivity at SeaWorld have not been getting research done on them and go under psychological stress so the killer whales are striking out on their

In the wild killer whales are very social animals and rely on the social bonds they create with their families or pods, in captivity these bonds are often broken. In the documentary “Blackfish” they reveal an unbreakable mother and daughter bond between Kasatka and Takara. Kasatka was a loving killer whale who was never vocal and never displayed violent behaviors, when her daughter Takara was taken from her, her trainers explained that for days Kasatka screeched, crying out for her daughter (Cowperthwaite)

The article, “Estimation of a Killer Whale (Orcinus orca) Population’s Diet Using Sequencing Analysis of DNA from Feces” by Michael J. Ford analyzes the sensitive predator pry connection. When there is an understanding of predators and prey, there is an understanding of ecosystem function. Because the killer whale is subdivided into discrete populations, based on diet and non- visible characteristics, there may be a tie between declines in prey that leads to decreases in that prey specialized individual

Introduction The killer whale has one of the few names in the animal kingdom that sounds distinctly like a super villain. While scientifically known as an orca, the term killer whale builds much more intrigue and excitement for corporations that are advertising their orca performances. For example, the orca Tilikum drew in crowds with his performances under the title “killer whale” for many years. Tilikum awed the audience as he propelled himself from the water and into the air in astonishing

Orcas or killer whales are whales or dolphins. Orcas share many similarities with both species of animals ranging from bone structure to teeth. Some of the more important similarities were eating and hunting habits. Some instantly noticeable similarities in all three was the blow-holes, breathing oxygen, and all three being aquatic mammals. Plus, all three give birth to living young. Another similarity between the three aquatic mammals is their forms of communication. Dolphins, whales, and killer whales

From the start of time, there are a few things we as people felt and knew we had to have in order to feel like we are wanted or needed, which also applies to our animal friends. The readings of Adam and Eve and Luna the Killer Whale demonstrated to all of us that we as people and animals need love and companionship, Adam and Eve experience several different feelings after the serpent convince Eve to eat from the forbidden tree and after convincing Adam to do the same. Changes happened after that

Killer whales, more properly known as orcas, have been kept in captivity since 1961, helpless victims of a blatantly commercial experiment which has seen dozens of wild orcas plucked from their families and forced to live in artificial social groupings which bear scant resemblance to their natural order. Unaware of their plight, millions of people flock each year to watch the orca show, seduced by the extravagant promises of the display industry. Glossy brochures herald a spectacle - billed "The

September 22, 2015 Do Killer Whales Actually Belong in Captivity? Ever since wild animals such as Killer Whales have been captured and kept in theme parks and zoos as amusement, there have been issues on whether they should or shouldn’t be kept in captivity. Killer Whales, otherwise commonly referred to as Orcas, have regularly been taken away from the sea at a very young age so they can be trained, raised and kept in theme parks for exhibition. Although theme parks no longer capture whales from the wild

shark is an easy choice but recently in the last couple years the killer whale has emerged as a challenge towards the Great White. The Killer whale is a worthy opponent towards the great white do to its bigger size and better and smarter hunting techniques. As history has shown great whites as dominant and scary they have been to the ocean as the apex predator they have been known to be the killer whales prey. When killer whales have attacked sharks they have turned the sharks upside down. When

sides come together, the argument boils down to one major point, should we “Free Willy?” Those who side with the whales, whether their reasons be emotional or defended with welfare standards, feel that the whales should be released back into the wild or into private coves3. The opposing side makes valid arguments against the release of the currently captive whales. Currently captive whales were either removed from the wild at a young age, albeit in a cruel way, or they were bred in captivity11. The

Killer Whales: How they Physiologically Inhabit their Environment Introduction Despite its name, the killer whale (Orcinus Orca) is in fact a dolphin. It is the largest member of the dolphin family and one of the most successful predators of the sea. Due to their body structure they are able to move through the water with ease. They can control their body temperature which is essential for living in cold waters. They are able to control their oxygen levels when diving and use echolocation making

Graph A represents recordings of a transient killer whale, whereas Graph B represents recordings of a resident killer whale. Both graphs show the changes in each whale type; one documents a drastic change over the course of four hours, while the other one—over the same amount of time—shows a more consistent pattern. A transient killer whale is represented in the first graph because, although a majority of the data shows the orca keeping to the higher points of the ocean, there are still points

Killer whales should not be held in captivity. It is |apitation beautiful orca whales that should not be pold from the blue ocean which is in there home for the beautiful killer whales. When they get old from the ocean the get gold from where there natural habitat.When they get old they go to seaworld and the only why they get food is if they do tricks. They get feed fish but when they are rethest in the ocean the only why they get food is if they canter fish or other animals. But if a human goes

In Blackfish, one of the most critically acclaimed documentaries of 2013, director Gabriela Cowperthwaite asserts that the inhumane practice of keeping killer whales in captivity is not the right thing to do. They are animals and they like to be open and free. Keeping killer whales in captivity is dangerous to the animals themselves, it makes them more aggressive, and also has the potential to harm and even kill the humans who work with them. Orcas are simply not meant for confinement. They are

The two graphs shows the diving patterns of transient and resident killer whales within a three hour range after midnight. It also shows the depth of the ocean where the certain killer whale is traveling to. I believe that graph A represents resident killer whales and graph B represents transient killer whales. In graph A, the average bottom depth is from 75 to 125 meters, except for one spike at a shallow depth of around 35 meters. As for the diving pattern, the orca has 7 deep dives, reaching

focused on killer whales in captivity, specifically Tilikum; a wild orca who was caught and exposed to captivity and its environment which eventually lead him to violently turn on his trainers at SeaWorld and even took some of their lives. This documentary examines how the difference from living in sea life to captivity can cause these whales and orcas to live up to their names. Blackfish discusses and argues how life in captivity for these whales is cruel and dangerous, not only for the whales but for

The experiment that the article “Longitudinal evaluation of leukocyte transcripts in killer whales” by Tatjana Sitt was based on is about different factors that are responsible for illnesses and stressing of domestic and wild killer whales. The research was conducted on 26 “clinically healthy” whales that contributed a total of 232 individual samples. After RNA extraction, cDNA synthesis, and Real- time PCR analysis the scientists found that the IL-4 transcripts were often absent, and the IL- 17
