The Conservation of Whales and Dolphins: Science and Practice, edited by Mark P. Simmons and Judith D. Hutchinson, is a book I have decided to utilize as a foundation piece for my final paper. This book contains in-depth information from multiple authors, compiled in chapter format. The compilations discuss many global issues revolving around the cetacean species, such as the protection and conservation of these water mammals and the various ways that they are endangered or harmed. This book also contains information about numerous international organizations and departments that regulate and maintain whaling laws and marine-life policies. An accredited author, often holding a degree in marine or cetacean biology or the head of one of the departments or organizations mentioned, writes each section or chapter. This book is an excellent source to use as background for my researched argument paper, because it contains up-to-date historical background on whaling and the numerous, international conservation efforts put in place.
This book opens with an introduction, giving general information about whales and dolphins. Written to provide a comprehensive review of not only all of the threats to whales, but also efforts and initiatives that are working to reverse the problems the cetacean species faces. From this very basic outline of traits and qualities of these marine mammals, an understanding is reached that helps the next portions of the book make more sense in context. This book does an excellent job of illustrating how there are many overarching reasons why the decline of this species is due to natural causes as well as other human caused reasons. The presentation of the biological reasons shows the scientific aspect of why c...

...of worldwide growth or manmade efforts, but others are due to the natural biological changes. These are all written in a statistical format, which includes information from respectable sources. Personally, all of these are important topics within the book, as they help to illustrate the overall importance of the IWC’s implemented polices, and how the polices could or have been undermined.
In conclusion, the compilations of writing in this book give me an excellent starting point for the final paper. Each section is well written and although a little wordy at times, they are fairly easy to read and understand. I believe the authors have completely valid sources that they used to compose their sections from, thus helping the book’s ethos to be significant and accurately put together.

The conservation of whales and dolphins: Science and Practice
Imagine yourself living in a bathtub for 25 years and you could do absolutely nothing about it. Wild orcas, better known as killer whales have been captured to entertain audiences world wide at aquariums. The most popular location being Sea World. Growing up in Miami, I could not control my excitement when it came time to go visit Lolita the killer whale at the Miami Seaquarium. To be able to see such an amazing creature right in front of me was mind blowing. How amazing is it that you can be face or face with an animal of that size? Well, I wish I'd known then what I know now. In the following paragraphs, I will start off with the difference between the life of a wild orca in the wild versus their life in captivity and I will end with reasons as to why families should not participate and give their time and money to these companies who commit such inhumane acts. I hope that towards the end of this essay, you will change your view on wild orcas and not look at them as just an animal that is used for entertainment purposes.
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.
The quest to gain international agreement on ethical and legal norms for regulation of whaling has had a long and troubled history. The modern phase of global concern over whaling ethics and conservationist management originated in 1946, when the International Convention on Regulation of Whaling was signed. Thus the International Whaling Commission was created. The International Whaling Commission was designed to control and mandate the whaling industry. From it’s beginning as simply a whalers club with scientific guidance, to the current day conservationist body; the IWC has undergone many revisions and transformations since the start. In 1982 the IWC voted to implement a “pause” on commercial whaling (which is still in effect today). Which major whaling nations, Japan, Norway, Peru, and the Soviet Union (later replaced by Russia) lodged formal objections, due to the fact that the moratorium was not based on advice from the Scientific Committee. One major disappointment of this regulation was due the fact that the moratorium only applies to commercial whaling. Thus, whaling under scientific-research and aboriginal-subsistence is still allowed. Japan and other countries have continued their hunt in the Southern Ocean Whale Sanctuary under the “scientific research” loophole. However, environmental activist groups openly dispute the claims and continue their rally to end the whaling industry for good.
Scientists had some idea to the evolutionary process of whales. “It has always been clear that aquatic cetaceans must have evolved from terrestrial mammals and returned to the water, and the forelimbs of recent cetaceans still have the same general pattern as that of land mammals.” (Walking with Whales) It was known fact that land mammals and whales were related. However, the change from ancient whales to modern whales is drastic.
“… 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.
Orcas, or killer whales are majestic giants of the sea. They are actually the largest type of dolphin. They have long black bodies with distinct white patches near their eyes. A killer whale can be up to 32 feet or more in length, and weigh up to 12,000 pounds. Females are a bit smaller, but live longer (Gorman). The name “killer whale” apparently came not because it is a vicious whale, but because it preys on whales. They do not have any natural predators, and they are considered the “top dog” of the ocean. Not even the great white shark stands a chance against these superb killers. “Unlike sharks, killer whales are cautious hunters, sometimes spending hours harassing a 1,000-pound sea lion so it can easily be drowned” (Francis). Orcas use many hunting tactics that are unique to their species, which is what makes them invincible.
The Makah’s seemingly domestic issue of whaling has and is taking on a larger international problem. The United States plays a large part in policing the hunting of whales, one of the most recent examples being the U.S.’s ...
In this research report I will discuss the Killer Whales unique characteristics; complex migratory patterns, how and why it is endangered, and most importantly how we can help them.
The capture and control of a breathtaking and majestic creature such as a killer whale is a very tedious subject. Most of the general public would enjoy viewing a show where these giant mammals jump out of the water and perform stunning tricks for viewer satisfaction. But what the public doesn’t see, or realize is that these animals could be severely depressed and could be lacking mandatory stimulation through social bonds and other factors the ocean could give them rather than an oversized bath tub. The ethicalities of keeping such an intelligent animal like an orca in captivity has been under scrutiny for years in the marine biology community. Despite the controlled environments for orcas, these environments cause psychological and social problems to the animals and are worse than nature. There is a distinguishable trait in killer whales in captivity that doesn’t appear in whales in the wild, the dorsal fin of the animal in captivity almost always droops over to one side or the other, and less than one percent of all whales in the wild have been recorded in having this trait. This could be directly related to the depressing life an orca in captivity faces in a closed off world with limited stimulation from the animals incredibly in depth social attributes.
In conclusion, education, research and conservation is a very important role that we can make to improve the lives of Orca whales, but at what cost? When you have to take an animal out of its natural habitat and deprive it of all its natural instincts, cause unnecessary emotional and physical problems, and put the lives of the whales and their trainers at risk, what are we learning? That it’s okay to possess them merely for our entertainment and profit? A wild animal’s life remains destroyed and many lives have ended, all for dangerous entertainment.
The origin of modern day whales, a mystery that has puzzled paleontologists for years, may have just been solved with the discovery of an ankle bone. This discovery might sound simple and unimportant, but the bones of these ancient animals hold many unanswered questions and provide solid proof of origin and behavior. The relationship between whales and other animals has proven to be difficult because whales are warm-blooded, like humans, yet they live in the sea. The fact that they are warm-blooded suggests that they are related to some type of land animal. However, the questions of exactly which animal, and how whales evolved from land to water, have remained unanswered until now.
Imagine being at home enjoying quality time with your family when all of a sudden someone comes into your home and takes you to prison for the rest of your life. No explanation, no warning, and no communication with your family, ever again. In a single moment you have lost your family, your home, and your freedom. That is a very scary thought, yet that is exactly what is happening to killer whales. We, as a society, are going to the ocean, and taking killer whales away from their home, and their families for the sole purpose entertaining us. These beautiful, majestic animals are suffering physically, mentally, emotionally, and they are dying prematurely because of our selfish actions. Mahatma Gandhi said “The greatness of a society
“Whales provide us with the food for our bodies, bones for our tools and implements and spirits for our souls.” “We haven’t hunted the whale for 70 years but have hunted them in our hearts and in our minds.” “Whales are a central focus of our culture today as they have been from the beginning of time.”
