...Brandon Farrow Mrs. Cox English 1 11/11/13 Navy Dolphins Dolphins are smart and amazing creatures. Scientists say they might almost be smarter than humans; they adapt really quick to their environment. The Navy is one branch of the United States armed forces that conducts military operations at sea. The Navy has programs with animals to help them protect the nation. The Navy and dolphins work together to control warfare in the water by using their sonar to track underwater mines and to keep citizens safe. These next paragraphs will explain how the dolphins and navy work together. One of the first dolphins used by the Navy was Tuffy. “Tuf Goy [Tuffy] joined the marine mammal program at Point Mugu in May 1964. By the end of September of 1964, Tuffy was retrieving a ring from the bottom of the lagoon at a depth of 200 feet” (Wood, 1973). In July of 1965, Tuffy was asked to participate in the Sealab II project with his main job being to help with the rescuing of a lost diver. Tuffy had a secondary job also of “carrying small objects-tools, for example-from the surface down to aquanauts working outside the habitat.” (Wood, 1973) “Tuffy repeatedly dove 200 feet to the Sea Lab II installation, carrying mail and tools to navy personal. To prepare for underwater tasks, Tuffy trained for six weeks and “learned to respond to a noise buzzer for the tests” (Presnall, 2002,) Judith Presnall’s book Navy Dolphins (2002), gives a visual image of Tuffy in training for rescuing lost...

...Dolphin notes Wikipedia (various) They have well-developed hearing − their hearing, which is adapted for both air and water, is so well developed that some can survive even if they are blind Dolphins feed largely on fish and squid, but a few, like the killer whale, feed on large mammals, like seals. Male dolphins typically mate with multiple females every year, but females only mate every two to three years. Calves are typically born in the spring and summer months and females bear all the responsibility for raising them. Mothers of some species fast and nurse their young for a relatively long period of time. Dolphins produce a variety of vocalizations, usually in the form of clicks and whistles. Dolphins are descendants of land-dwelling mammals of the artiodactyl order (even-toed ungulates) J.G. Williams The primitive cetaceans, or archaeocetes, first took to the sea approximately 49 million years ago and became fully aquatic by 5–10 million years later.[22] WIKIPEDIA channeled vibrations from the jaw to the earbone which occurred with Ambulocetus 49 million years ago, a streamlining of the body and the growth of flukes on the tail which occurred around 43 million years ago with Protocetus, the migration of the nasal openings toward the top of the cranium and the modification of the forelimbs into flippers which occurred with Basilosaurus 35 million years ago, and the shrinking and eventual disappearance...

...Dolphin Swimming The cool blue water soothed my skin; the sun soaked my hair; the squeaky voice of my new dolphin friend filled my ears. These memories fill my head when I think of San Diego. My vacation in California brought many exciting adventures and new experiences that will always be special to me. It all started when I was eleven years old and I heard that swimming next to a dolphin, which at the time was one of my favorite animals, could become a reality well I begged my mom to the point of annoyance and she finally gave in. So, the following Friday we started our drive to Sea World in San Diego, California. Once we arrived at Sea World my family and I went to find out the price and requirements. We found out that to swim with a dolphin I had to be over the age of ten…Check! At least four feet tall… Check! And that was it, after a quick lesson I was ready to go. As I was waist deep in water next to the dolphin I could hear the rustles of the water as water splashed onto my face and I could taste the salt water emerging into my mouth as the dolphin and I played around. The instructor taught me hand-signals which was how I could communicate with the dolphin. Also, I learned that dolphins can understand over one hundred human words and phrases. This was just one of many interesting facts I learned on my trip to San Diego. Furthermore, being with the dolphin, whose name I can’t recall, was incredible. This was a moment I won’t ever forget and my only issue is I wish...

...Dolphins have the second highest brain power in the animal kingdom, just behind humans. The academy award winning documentary, The Cove did a wonderful job on shining a light on the questionable hunting practices on dolphins in Japan. Dolphin hunting in Japan as practiced in The Cove are unnecessary and cruel. Dolphins killed in the Taji dolphin drive hunts are several times greater than those in the antarctic and most other seas. (WDC Dolphin Hunts). Almost 23,000 dolphins and other sea mammals are killed or captured in Japan every year, by the ever-growing countries whaling industry (WDC Dolphin Hunts). The typical practices used in Japan to hunt their dolphins is very unnecessary, cruel and should have greater consequences towards those unethical practices of dolphin hunting and capturing. The way in which the Japanese gather dolphins and kill them is flat-out unnecessary. The fishermen herd the dolphins towards land into a sheltered cove and then cover them with a net to prevent their escape. They then used to...

...whereby more than 100,000 living exhibits of marine life will is slated to start operations in 2012, at Resorts World Sentosa (RWS). The aim of this MLP, as cited by RWS, is to ‘enrich public understanding of marine conservation’. It also wishes to serve as a public showcase for education and research of marine wildlife. The MLP houses 25 indo-pacific bottlenose dolphins as well. There will also be a whale shark exhibit at the MLP. However, before the opening of the MLP, there have already been issues and concerns being raised by the public and some animal welfare organizations, with regards to the captivity of these dolphins and the whale sharks. As animal captivity has been a controversial issue over the past years, an issue that undoubtedly concerns the public and animal welfare organizations (such as SPCA and ACRES) is that RWS seems to only be bringing these dolphins for amusement to the public, henceforth generating more profits when RWS’s dolphin shows become popular. The question is – is RWS doing anything about the public’s comments towards its actions? Is RWS really excessively importing these bottlenose dolphins for the money or for the greater good of its species? Another issue that the public has with RWS housing the whale shark exhibit is that whale sharks, which are being held in captivity, have low survival rates due to various reasons, such as limited captive space, stress from being unaccustomed to captive life and so on. Surprisingly, after SPCA, ACRES...

...Margaret Morrison 11/12/2013 Legal Environment of Business Tues/Thurs 12:30-1:45 pm Hostile Environment in the Workplace and the Miami Dolphins A hostile work environment includes any situation targeting race, color, religion, sex, national origin and even such aspects such as pregnancy, age or disability that affects a person’s ability to perform in the workplace. In this short analysis, I will go on to discuss racial discrimination, an ongoing issue in some workplaces, despite all the progress and efforts our country has made over the years. The NFL, a very culturally diverse organization, much like any professional sport in America, is starting an investigation into one of the Miami Dolphins’ players, Richie Incognito for his racist attacks on his teammate Johnathon Martin. The Miami Dolphins suspended Incognito around midnight on November 3rd. Incognito did many things to create a hostile work environment for Martin. He sent him text messages threatening to kill him, he forced Martin to pay $15,000 for a trip to Vegas, along with the thousands of verbal assaults. Martin was afraid to speak up, being only a second year player, in fear of being called soft. However it seems that this is no longer an innocent hazing affair as it is extortion and intimidation. Finally, Martin took the high road, and walked away from the Miami Dolphins. Making him look like more of a man, than Incognito will ever look. Now unfortunately, this isn’t the only instance, many of the rookies...

...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 of...

...and most cost effective way is to organize a group and rent a van in Dumaguete to bring you to the Capiñahan Wharf. This will cost approximately P1,300. The rental boat that will take you out to the Strait costs between P2,500 to P3,000 depending on the number of people boarding. Being in a group allows you to split the transportation costs. If a van cannot be availed of, jeepneys plying the Dumaguete-Bais route cost only a cheap P15, and another P10 to take you to the Capiñahan Wharf. Dolphin and Whale Watching in Bais City Dolphin and Whale Watching is fast becoming a national attraction as well. It has gained popularity among travelers both local and foreign because of its appealingcombination of activities. The adventure starts with a cruise along Bais Bay then out to Tañon Strait, the natural habitat of several whale and dolphin specie. Among the kinds of dolphins you may encounter during the trip are , pantropical spotted dolphins, bottlenose dolphins and long snouted spinner dolphins. Melon headed whales, short finned pilot whales, pygmy sperm whales, pygmy killer whales and dwarf sperm whales are commonly found in the Tañon Strait too. After the show of sea mammals, you head out to Manjuyod White Sand Bar where the boat temporarily docks. Here you can savor your lunch of grilled pork and fish while looking out into the blue sea and sky and the white sands of Manjuyod. This place is also ideal for swimming, sunbathing, snorkeling and scuba diving in the nearby reefs...

...DOES MILITARY SONAR KILL WHALES? In this report I’m going to argue against the concerns that a dolphin and whales conservation group have produced, and I will support my argument with evidences to prove my choice. I’m also going to use couple of charts and data to back up my answers. A dolphin and whales conservation group have produced artificial report. For instance they wrote ‘whenever there is a military sonar exercises, up to 200 whales die as a result of sonar damage’, which was exaggerated, 200 whales and dolphins died just once and that was on Manila Bay, Philippines in 2009. When we look at the data we can see the average number of cetacean stranded is 28.2, and ranges from 1-200 The reason I put the second graph is because it said on my sheet to plot a bar chart of the number of deaths at the time of naval exercises on the axes (3. 1) – hope it makes sense The secondary source from table one has a limited analysis; they have missed out so many years such as 2001, 2007 and they doubled up the year 2008, and it is in various locations. The second statement ‘Whales and dolphins are being damaged all around the world by military sonar exercises’ needs to be shown by having more locations that show that places with no sonar activity have no stranding. They have not told us how many military sonar exercises there were in one year or how many stranding there are when there are no military sonar exercises. They have also not told us how big the sonar exercises were so...

...evolved as a result of environmental changes within their habitats. To understand better this paper will examine a diagram of a dolphin and give details about how the dolphin has evolved physiologically and has become adapted to fit the environment. Dolphin Characteristics Dolphins inhabit all oceans and the seven seas; some also inhabit larger river systems. Dolphins are extremely social organism and use communication for the function of hunting, defense, and reproduction. In general a dolphins live pods of up to a dozen individuals. Dolphin pods can emerge temporally forming a superpod the emerging pods may exceed thousands of dolphins. Attachments in pods are not set; interchange is regular. On the other hand, dolphins can generate great social bonds; they will remain with wounded or individuals in poor health, even assisting other dolphins to breathe by bringing them to the surface if required. Dolphins are carnivores their diet consists of fish, squid, octopus, cuttlefish, crabs, shrimps, and lobsters. Dolphins are a food source for sharks, and killer whales. The most dangerous predator for the dolphin is humankind. Man slaughters dolphins for their meat, fat, and for being in the same location where they fish. There studies at this time being done to evaluate the influence of pollution in the water and the effects on dolphins. Dolphins give birth to live young, and the mother nurses the calf with her milk and provides care. The calf is nursed by the mother for...

...Species: delphis, or better known as, Dolphin. Dolphins occupy all oceans and major seas, even some are in larger river systems. This paper will cover characteristics of a dolphin, the ancestry to the modern dolphin, and what adaptations the dolphin has gone through to be the survivor it is today. Characteristics. Dolphins are very social creatures and use interaction for the purpose of hunting, defense, and reproduction. Normally a dolphin will stay in a long-lasting group of 2-40 animals called pods, but larger groups of hundreds of dolphins have been reported and those are called herds. Dolphins are carnivores that feed on fish, squid, octopus, cuttlefish, crabs, shrimps, and lobsters. Dolphins are food for sharks, killer whales, humans. Man is the most dangerous predator for the dolphin. Humans will kill dolphins for their meat, their fat, even for being in the area they are fishing. Additionally, studies are currently being done to evaluate the affect of pollution in the water on dolphins. Dolphins bear live young, and the mother nurses the calf with her milk and provides care. The calf is nursed one and one half to three years and a mother will stay with her young three to eight years. Dolphins are believed to live about 30 years. Dolphins vary based on their ecosystem and what is required for them to survive in their niche. In the Gulf of Alaska there are few dolphin species, one of which is the pacific white-sided dolphin. This dolphin has a short, rounded beak with about...
