Topic: Dolphins Introduction I. How many of you guys have been to sea world or swam with dolphins? Well if you haven’t, I bet you have at least thought about the possibility of going or know someone who has done it. II. The popularity of seeing dolphins and being able to swim and connect with them has caused them to be slaughtered every year in Taiji, Japan. III. First, I will inform you about Dolphins in the wild, and Secondly I will discuss about Dolphins in Captivity while Lastly I will talk about the slaughtering of Dolphins in Taiji Japan. Body I. Dolphins have captured the hearts of millions of humans all around the world. They are loving animals, 1. As I stated earlier dolphins are highly intelligent animals and it is obvious they are well loved by humans. …show more content…
Dolphins are high intelligence animals and also very active in the wild, so in captivity, they are stress and depressed because the boredom they go through being in a tank. a)In some cases, there has been situation, dolphins have shown to be aggressive and bitten people because the stress they are under. b)Some Marine parks treat these dolphins with anti-depressant, Prozac or tranquilizer, which causes them to become even more stressed. 3.Another problem dolphin run into, is dolphin urinate 3 times more a day than humans, and dolphin pee are known to have many bacteria and virus that can effect also humans. a) There have been cases, where humans who swim with dolphin get a flesh eating disorder (MRSA) Many dolphins die because of the environment there in, does not get clean often as it should. b)Dolphin are marine mammals, so people are not aware but dolphin can pass disease to human and human can pass disease to human. Transition: Dolphin is a million dollar business, so cause the increase the fishing of dolphins. III According to documentary “the cove” Annual dolphin hunting season in Taiji, Japan is very important event, and every September they capture hundreds of
Out of the 156 whales they have taken into captivity from the wild, 129 are dead. Including orcas bred within SeaWorld, at least 165 have died in their facilities (Schelling). Another falsehood SeaWorld claims is that collapsed dorsal fins are completely normal and common of all male orcas. It is actually quite rare to find in the wild, while every single one of their male whales has a collapsed dorsal fin (“8 Shocking Facts…”). SeaWorld also guarantees that they never separate a calf from its mother and even have posted a picture of a baby and its mother as proof. What they didn’t tell the public was that soon after that picture was posted they shipped the calf off to Spain alone to a different park. A past trainer even said that there had been at least 19 separations of mother and calf that he knew of at his location. All of these factors previously stated added up have a large influence on the whales mentally. Many whales are afflicted by psychosis and anxiety and in turn are given drugs such as Valium to keep them performing in shows. There have been various occasions, often swept under the rug by SeaWorld and away from the public eye, where the drugs didn’t work enough (Schelling). There
Entertainment is a word that invokes feelings of fun and pleasure. It is an exciting time with family and friends filled with joy and laughter, especially at amusement parks. However, what about the whales entrapped at amusement water parks? How do they feel? Are they content with their environment? Perhaps once you view Blackfish by Gabriela Cowperthwaithe, you will begin to have an understanding of how the whales feel.
People believe that it is no different than training a dog to perform tricks in order to receive a treat as a reward. Some scientists and ecologists also believe that rather than leaving some orcas that are abandoned by their pods, these orcas would be able to live out their lives in captivity. Captivity is not always a bad thing for many wild animals. In fact captivity is what has helped to save the lives of many endangered species and has allowed them to survive and be seen thousands of people around the world. Orcas are an especially hot topic in the science and ecology fields across the globe. Orcas are the largest member of the dolphin family and are extremely unpredictable creatures in the wild. These facts being true makes it extremely difficult and nearly impossible to study the lives and mannerisms of killer whales in the wild. Simply because of this some scientists believe that it is best to hold some orcas in captivity in order to study them and learn more about the psychological stages and happenings in the population as a whole. In some cases it is best for the orcas to be in captivity. The United States Fisheries have set rules and regulations that ensure that all the marine life that is held in captivity has a purpose. This purpose must be educational in some form. The fisheries also mandate that the tanks the orcas are held in are kept at a certain standard to

In the past twenty years a large amount of bottlenose dolphin have been killed due to the tuna fishery. In the Eastern Pacific swim large schools of tuna, these shoals tend to be under herds of dolphins, for some unexplained reason. Because of this, fishermen can easily find schools of tuna. The tuna are being caught under purse seine nets, which encircles the shoals of tuna and then is pulled back on board the fishing vessel, catching both tuna and dolphin. Initially the mortality rate was 500,000 each year for dolphins alone. Although some efforts are made to encourage the dolphins to leave the net by backing down part of the net, which allows the dolphins to escape, there are still a large number of mortalities (Bryant). On the other hand, in the last few years there has been dramatic progress in stopping the fishing industries from using purse sine nets. It has been found that dolphins are in immediate danger of extinction if these fishing techniques don’t stop.
An orca, more commonly known as a killer whale, is currently one of the largest marine animals held in captivity. Countless arguments are being made, supporting and opposing captivity of orcas to be exploited as circus animals in theme parks around the world. Throughout recent history, Sea World trainers have been injured and killed by the orcas and the whales, and the whales themselves have been observed as severely depressed. If Sea World releases the whales, they would undergo an immense economic downfall and the whales would be too weak to survive in the wild if they were freed. Since the first Sea World park opened in San Diego, California in 1964, common questions have arose concerning the well-being of orcas in captivity, the dangers of humans training them, the physical capability of whales theoretically being released, and the psychological differences between whales living in the wild versus whales living in Sea World's confinement.
Then, on top of that stress, further stress is added when the Orcas are placed into tanks with other Orcas that are not members of their pods, or with different species of dolphins altogether.... ... middle of paper ... ... We might constrain nature for our enjoyment -- but sometimes, the show's going to have blood in the water.
“… building a tank the size of Rhode Island wouldn’t be large enough for a six-ton male killer whale such as Tilikum, an animal capable of swimming 100 miles a day,” states an anonymous whale expert. Whales have been in captivity since 1861 when P.T. Barnum displayed the first live whale that was captured in Canada. However, Barnum had no idea how to care for the mammal and it died after only a week in captivity. (Animal Legal and Historical Center, 2014) Being up close with killer whales could give us some clues about how they interact with each other, including physical behavior, their dialect, and how their pods work together as a family unit. However, what we are finding is that whales who belong in the wild are suffering in captivity. Killer whales have no record of ever harming a human being in the wild. In captivity, there have been many incidents of killer whales harming or even killing their trainers. What would cause them to do this in captivity, but not in the wild? They have been known to resort to aggression toward themselves and each other, in what scientist believe to be a stress induced behavior. (Animal Legal and Historical Center, 2014) Evidence against having these wild animals in captivity is increasing and we need reevaluate the value of capturing and holding killer whales for our educational purposes, enjoyment, and profit.
Cetaceans are thought to be some of the most intelligent species on this planet. Popular culture has embraced the idea of cetacean intelligence with shows such as the 1960s hit TV series Flipper, where a dolphin is used to help fight crime. In his comedic science fiction novels, the Hitchhiker’s Guide to the Galaxy, author Douglas Adams suggests that dolphins are the second most intelligent creatures on Earth, behind mice and above humans. Although most scientists would probably argue that humans are the most intelligent species, the behavior and brain size of dolphins and other cetaceans suggests that they too are intelligent. This paper will briefly describe the reason some scientists believe cetaceans are intelligent species and then give examples of scientific studies, which suggest cetacean intelligence. Since bottlenose dolphins and orcas are the most widely studied cetaceans, the survey of field studies will primarily focus on these two species. At the end, this paper provides an argument of why some scientists discredit the high degree of cetacean intelligence.
Is a dolphin a person? Most people would automatically dismiss the question, but in reality, this question can be discussed on a very complex level revealing that the definition of a person is not so black and white. Mary Midgley sets the stage to her narrative by telling the story of a specific court case that she uses as a reference on many occasions. In May of 1977, two men set free two dolphins who were used by the University of Hawaii’s Institute of Marine Biology for experimentation. Kenneth Le Vasseur, one of the men who was standing trial, told how these dolphins were suffering through unfair conditions such as diminishing food rations, isolation from other dolphins, and loss of toys. Based on this information, Le Vasseur and his counsel tried to use the “choice of evils defense” which states that an act, which would typically be considered unacceptable, would be allowed if it would lead to an avoidance of a greater evil or crime against “another”. This defense was rejected on the grounds that the judge declared that a dolphin was not considered to be “another” and instead it should be considered property. Today in our society, it is a common perception that a person or “another” indicates that you must be a human being. Midgley investigates this perception as well as the question of how do we classify what is and what is not a person as well as the moral implications that comes with the title.
The utilitarian foundation of argumentation indirectly taken by the producers of this film is one that focuses on the consequences as a means of determining what one ought to do. Utilitarianism argues one ought to commit acts that affects invoke more pleasure than pain or suffering. In the case of The Cove, Richard O’Barry and Louie Psihoyos , as well as other individuals chosen for the task of videotaping and creating the exposé, continually argue a few major points. One area where Richard O’Barry disagrees but the others seem to care little is the fact that dolphins are herded and initially chosen for performance purposes at water parks around the world. This showcases the manner in which many see the positives of entertaining individu...
If you have ever been to Sea World, you may have noticed the orcas’ collapsed dorsal fins. The trainers will tell you that this is normal. While it’s true that all captive adult male orcas have collapsed dorsal fins, in the wild, less than five percent of adult males have this condition. It is caused by their unnatural environment and is the sign of poor health (Rose). In the wild, orcas dive to depths of nearly 200 feet; however, their deepest tank at Sea World is only 40 feet deep. Spending so much time near the water’s surface causes the orcas to have constant sunburn (8 Reasons). Incompatibility among captive orcas leads to bullying and aggressive behavior. Aggressive orcas are known to “rake” their teeth down the side of other orcas causing open wounds. Captive females have been known to act aggressively or even reject their newborns. This behavior is not common in the wild. It may be caused by poor psychological development due to unnatural social grouping
This argument about Orca whales is very important. The abuse that these animals go through is unbelievable and uncalled for. They face starvation, dorsal fin damage, and withdrawals from not seeing their family if they were taken from the wild. Orca whales love to play but it is hard when they are being abused. Whales in the wild have dorsal fins that stand straight up (Killer Whales Don’t Belong In Captivity). The whales at any marine park have dorsal fins that
Commercial whaling has essentially seized on the clear claims of such, but Japan and other nations are ever so slightly getting closer to that boundary. “We should remember in our dealings with animals that they are a sacred trust to us.
There are many reasons why dolphins are very intelligent animals, there are 33 different types of marine dolphins, 4 types of river dolphins, and 6 types of porpoises (dolphins are mammals). Some of the dolphinspeople may think they would be whales, because of their looks, but they are dolphins. Dolphins have a strong behavior; they are very social and travel in groups together. They commonly swim in groups of 2-15 . Severalof different groups of dolphins may temporarily join, for several minutes or hours. In the open waters of theocean, some dolphins will leave their group and change associates and adapt with different dolphins threw outtime (Dolphins communication). In the groups, some members will form a strong bond with one another in thepod. The sizes of the groups tend to increase with the water depth of the ocean and the openness of the habitat, this usually happens when protection with strong with each other and foraging st...
