Bottlenose dolphins became part of a United States Navy program in 1959 for the purpose of conducting scientific research into their sonar and hydrodynamics in hopes of getting design ideas for submarines, ship hulls and weapons. It was discovered dolphins hear and navigate in the water by using their natural sonar, which happened to be more precise than most fabricated sonar systems. In the mid-sixties, Navy dolphins were used as mail carriers to underwater laboratories in their home of San Diego, California.
As technology and scientific discoveries floundered through time, new uses for the animals came into play. For example, dolphins were trained to protect ships, submarines, and divers from any danger. If a dolphin were to find an enemy diver in the water, it was taught to lead the diver into dangerous waters. The dolphins were also trained for search and recovery work to find objects (usually mines) embedded in the mud or sand of the seabed.
Today, in addition to the bottlenose dolphins, the Navy program includes sea lions and white beluga whales. The sea lions have excellent hearing and can dive much deeper than dolphins. They are trained for marking mines and retrieving torpedoes or practice mines, all while being more efficient than human divers. The white beluga whales dive deeper than the sea lions to recover inert torpedoes and are currently on loan from Sea World.
Although it is remarkable that these marine mammals are capable of so much, there are things the public does not know. According to classified statistics, twenty-three out of forty-three animals died while being transported from their natural habitat to foreign aquariums for training. Another thing the public does not know is in reference to a similar marine mammal program in the Soviet Union. It has been reported that Soviet dolphins were trained to do "kamikaze" missions. Explosives were supposedly strapped to their backs and they were sent out to destroy enemy submarines. According to statistics, about two thousand dolphins have died on these, and similar, missions.
In America, the Navy's Marine Mammal Program was once a top-secret affair, and rightfully so, if they wanted to avoid animal activists. The first documented use of dolphins on duty was during the Vietnam War in 1970. Dolphins were used to warn of approaching enemy divers. In another assignment, dolphins were used to protect Navy ships in the Persian Gulf and Iraq-Iran War.
The Sea Shepherds are group of volunteers who try to protect the sea animals, and capture criminals who kill the animals without permits. Their website has many purposes, one dedicate to collect donations from the reader. Furthermore, they want to protect the ocean wildlife. The website audience includes people who want to protect the ocean, and they want to save the sea animals which will likely be extinct. They offer the audience a chance to donate, volunteer, and stay up to date with ongoing issues involving marine life. This website is outstanding because the sea shepherds host a successful website that effectively reaches out to the audience through appealing to the reader's emotions, logic, and credibility.
One of the most common dolphins that are found in southern California is the bottlenose dolphin (Kelly). The bottlenose dolphin is mainly found in coastal waters between 45 degrees north and 45 degrees south, also in Northern Europe waters. It is believed that there are two types of bottlenose dolphin regional wise: oceanic form and coastal form. This species is studied the most by biologists (Jefferson). The coastal population lives in fairly open groups with twenty or less in a pod, some groups are found to contain more in open ocean. It is not uncommon for these species to interact and breed with other species, as would a human interact with other diverse humans. The dolphins feeding behavior is adapted to the availability of resources. They sometimes are known to work together to catch fish from large schools, they also trail behind large fishing boats to catch what falls behind (Leatherwood).
Your viewpoint on killer whales is forever changed. These are the kinds of situations that should and could be prevented. According to Sally Kestin of the Sun-Sentinel, mammals actually live longer in the wild than in aquariums. There is a problem with keeping marine mammals in captivity because of Tilikum’s attack on trainers, other various attacks, how the orca industry started and the psychological effects of captivity. The problem could be solved by using sea pens and making more laws protecting marine mammals.
They are the second smartest animal in the world. They nurture their young for most of their lives. They also socialise with any creature, unless they show signs of harm. Dolphins make very popular playmates and will come up to humans for almost anything. They rely on each other to live. They learn quickly and communicate well with one another. God designed dolphins with unique physical features and behaviors in order to glorify Him.

Orcas, also known as killer whales, are amazingly intelligent and are a top predator, much like humans. However, when the top predator of the ocean collides with the top predator of land, the situation can become fatal for both humans and the whales. Holding these incredibly massive marine animals in captivity is not only inhumane and detrimental to the whale’s health, but also a potentially fatal activity for humans to participate in.
Ways to early detect would be self-breast exams at home, annual mammograms and genetic testing for the BCRA1 and the BCRA2 abnormal gene. It has been said that when people are tested for the abnormal gene and are found to carry it, it is normally passed from either parent. Not only do women develop breast cancer, but men are also at risk. If detection is caught early enough there can be a high survival rate. Some symptoms and signs are a lump, change in size or shape of breast, nipple pain, discharge or bleeding of the nipple, change of skin color and texture, or breast becoming swollen or feels warm. It is advised to seek medical attention upon discovery of signs and symptoms. It can possibly allow a better treatment option for
From the earliest days of man, creative uses for animals have arisen. Since the time of them Mongolian chief Timur and Sultan Muhmad Khan, many military uses have been created. These creative ideas are still created today, now modern day countries find many uses of animals such as monkeys, seals, dolphins, goats, elephants, and other animals in the military. Though the truth is right in front of our eyes, many people do not believe that these animals show up on the battlefield and in the oceans with humans defusing bombs and attacking enemies on the other lines.
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.
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.
This progression of Pip’s life tests him many over. He tries again and again with haste to move towards his one true goal borne upon a children’s folly that grows to be his all consuming desire. He resents his current status as mere orphan smithy boy, common in all respects to his eyes, and fails to recognize his own strangeness in rejecting his allotted path in life. His father figure, Joe, advises that his own questioning is uncommon enough but he simply disregards fulfilment in being himself, believing himself to be the one true, harsh, judge of his character, he is simply not one to back down on his ideals.
The endangerment of marine species has, is, and will be a major issue for generation to come. There have been quite a few actions to help solve this issue since it first came about to the public’s attention. Non have been more affective that what started the movement, and will continue to advance the movement for those endangered species. Avocation of organization that defend and strengthen the Endangered Species Act, hold federal agencies and other accountable for their actions, advocate for private reservation with lack of funding, protect and restore habitats, and reduce threat to wild life. However, those organizations that advocate the endangered marine species have their downsides.
...r. Even though they live in the ocean all their life and also amusement parks, dolphins are mammals, not fish. That makes them very intersting animals because of all the charactics that they have that people would have never known about. Dolphins are by far the most intelligant marine mammals in the ocean.
These dolphins are the type of dolphins common people would see at the Zoo or on a T.V. programed performance. Like the Common Dolphins, the Atlantic Bottle-Nosed Dolphins are highly skillful echolocators. They can produce a range of sounds, like a click, using it to analyze any object around them in the ocean (Whitfield 114). According to Whitfield on page 114, they can produce up to 100 clicks a second. They will use these clicks to also find food. They mainly eat Bottom-dwelling fish in inshore waters or surface swimming fish. They can do many other objects with their echolocation finder and using their
