Dolphin Research Paper
Dolphin

Dolphins are marine mammals that are closely related to whales and porpoises. There are almost forty species of dolphin in seventeen geaner. They vary in size from 1.2 m (4 ft) and 40 kg (90 lb), up to 9.5 m (30 ft) and 10 tonnes. They are found worldwide, mostly in the shallower seas of the continelnta shelves, and are carnivores, mostly eating fish and squid. The family Delphinidae is the largest in the Cetacea, and relatively recent: dolphins evolved about ten million years ago, during the Miocene. Dolphins are considered to be amongst the most intelligent of animals and their often friendly appearance and seemingly playful attitude have made them popular in human culture.

    Bull Sharks Research Paper

    Carcharhinus Leucas or bull sharks are the only species of sharks that are able to travel long distances and spend extended periods of time in freshwater environments. Although many people disagree, I believe that one of the bull sharks’ main reason for entering freshwater is to find breeding grounds. There is evidence that supports this theory, and it seems to me a very logical explanation, however it is a controversial concept. In this paper, I will discuss what physical characteristics allow bull sharks to survive in both marine and fresh waters, and attempt to understand whether they do this…

    Diving Humpback Whale Analysis

    I went to the Art Museum of South Texas to take a look at the artwork they had on display there. I found that they had an exhibit called Liquid Light and it included black and white photographs of the sea and its inhabitants. In this exhibit there were works from 10 different photographers and while I loved and developed an appreciation for many of the photographs on display the one that caught my eye was the “Diving Humpback whale” by Wayne Levin (born 1945). This paper will focus on why Wayne Levin takes photographs of the underwater world and why the “Diving Humpback Whale” photograph was my favorite.…

    Killer Whales Research

    With research and studies being conducted on both wild and captive Killer Whales, data and information has been generated that adds question to the health issues associated with captivity. “The killer whale (Orcinus orca) has proven to be among the most difficult of all species to hold adequately in zoological facilities. The killer whale is a particularly large-brained and long-lived species who evidences a high degree of social complexity in the wild.” (Noonan) Their behavior and relationships with other whales within the family, known as a pod, creates an immense bond between the animals. Whales that were documented inhabiting the Pacific Northwest, remain in their natal group for most, if not all, of their life. (Robeck) When in captivity,…

    Killer Whales Research Paper

    The flippers of both sexes are large and oval, unlike those of any other toothed whale. Killer whales may be solitary or live in groups of 2 to more than 50 animals. They feed on fish, squid, marine birds, pinnipeds (see Seal), and even other cetaceans. They generally cooperate during hunting, especially when feeding on large, warm-blooded animals such as penguins, seals, and porpoises. Killer whales have even been known to prey on blue whales, the largest species on earth. In most areas, killer whales have specialized feeding habits. In the Pacific Northwest of the United States and the Pacific Provinces of Canada, for example, resident populations feed mainly on salmon and other near-shore fishes, while transient populations feed primarily on harbor seals and porpoises. In several places in the southern hemisphere they habitually beach themselves as they rush ashore to take seals or sea lions in the turbulent surf zone, moving back to deeper water afterward. Killer whales use echolocation to gather information about their surroundings—that is, they send out high-frequency clicks that bounce off prey and other objects and they interpret the returning…

    Dolphin Slaughter Research Paper

    Brutality, crimson waters, what a gruesome spectacle it is to see the horrifying sight of dolphins being slaughtered by Taiji fishermen for a profit. In a total of six months the murderers will catch and kill about twenty three hundred of Japan’s annual dolphin population of twenty thousand dolphins. The capture of the dolphins is sinister. The fishermen bang pipes together under the water to throw off a dolphin’s hypersensitive sonar in order to drive the dolphins into a large hidden cove that is then closed off by nets ensuring no escape. Bringing the dolphins to the cove looks like an orchestrated ballet when you see the boats performing their moves out on the horizon. What a person cannot see or even…

    Bottlenose Dolphin Essay

    Bottlenose Dolphins have complex social and communication skills and have been observed to form social alliances, such as males cooperating in pairs or triplets to control the movements of females (Connor et al.). They have been observed to use tools as well; specifically wild Bottlenose Dolphins were documented using sponges as foraging tools (Krutzen et al.). Bottlenose dolphins are also known to engage in cooperative hunting, where dolphins have been known to take specific roles where such as “harrying shoals of small fish towards a waiting cordon of 'barrier' dolphins, then herding them up to the surface” (Hopkin). Finally, and perhaps most remarkably, Bottlenose Dolphins in captivity for research have been observed to seemingly cooperate and problem solve when presented with a task (Kuczaj et al.). Although there is still a lot of controversy and debate over just “how” intelligent Bottlenose Dolphins, and other species of the Dephinidae family, are there is a lot pointing to the idea that these organisms are not “primitive” in their…

    Dolphin Captivity Research Paper

    As the cognitive abilities of dolphins become better understood, a conversation over whether dolphins should be kept in captivity has arisen. We are discovering everyday just how intelligent dolphins are, in fact they’re one of the smartest species on the planet. Which is why the question comes up: What are the effects of keeping such an intelligent species in captivity? With a living area that is constricted and empty, there appears to be very little room for a dolphin to grow, both physically and mentally. Dolphins are highly social creatures, so when that aspect of their identity is severely limited, how does that affect the creature mentally. In addition, dolphins grow accustomed to the life given to them in captivity. For example, being…

    Dolphin Trainer 33

    Biology and Chemistry. Many trainers pursue in Biology, Marine Biology, Psychology, and Animal Behavior in college. There isn’t any specific college for marine mammal training, but the college you choose will depend in your interest. Once you get your degree in the field you want to study then you can start the stages of becoming a dolphin trainer which include many different methods of studying and learning the animal’s behavior. Brown says “Training is a very much two-way communication process” (20) the trainer must adjust to the dolphin also; you cannot force the animal to do something that it does not wish to do.…
