A Research Study On Bottlenose Dolphins - 1188 Words

Bottlenose dolphins are among the most familiar cetaceans, just as whales. The Bottlenose dolphin is a primitive member of the subfamily Delphinine. Bottlenose dolphins are grey, varying from dark grey at the top near the dorsal fin to very light grey and almost white at the underside. There are two ecotypes of bottlenose dolphins the coastal and the offshore. The Coastal dolphin has a small body and large flippers to increase agility and heat dissipation. They have a limited movement into offshore waters and like shallow warm water near the shore. Coastal dolphins for the most part remain in their region. The Offshore dolphin has a large body to help conserve heat and defend itself against predators. They are less restricted in range and movement and like deep, cold waters. Offshore dolphins in the North Atlantic have migratory patterns that follow prey distribution. Bottlenose dolphins live in groups typically of 10–30 members, called pods, but group size varies from single individuals up to more than 1,000. In a case study performed by Randall Wells who is the leader of the longest study of dolphin population since 1970, it was discovered that there are three main factors that influence migration: Seasonal changes in prey location, predation pressure and reproductive requirements. (Wells, 1980). In the fall dolphins follow mullet fish when they migrate from the bays into the Gulf of Mexico to spawn. Dolphins experience the most predation pressure during the summer whenShow MoreRelatedThe Research On Marine Mammal Captivity1332 Words   |  6 PagesIntroduction: In recent years, animals in captive environments such as zoos and theme parks have grown more controversial. The literature I have reviewed focuses on a particular group of animals in captivity, cetaceans. Cetaceans include whales, dolphins, and porpoises. The literature includes a range of themes, from their unique level of intelligence to why they may mentally and physically suffer in captive environments. However, it all connects to how and why these animals live and behave differentlyRead MoreThe Importance Of Effective Communication And Human Communication2537 Words   |  11 Pageshumans communicate; however, some research suggests that animals use language-like abilities to communicate as well (CS212OC M4, L1, F, 2014). For example, we studied the communication skills of parrots and bees (two animals thought to possess astonishing communication abilities), and compared their communication practices to human communication practices (CS212OC M4, L1, F, 2014). Throughout this p aper, we will be looking at the communication skills of bottlenose dolphins, while comparing and contrastingRead MoreDolphin Foraging Techniques Essay examples1358 Words   |  6 PagesBottlenose dolphins are known to use sea sponges as tools when foraging for food in the ocean. This behavior is referred to as â€Å"sponging†. â€Å"Sponging† refers to when these particular dolphins put a sea sponge over their rostrum (snout area) and use it to help collect food. Different explanations have been given as to why Bottlenose Dolphins engage in this behavior. It has been perceived that young dolphins learn this behavior from their mothers. Researchers are also exploring the option that a differentiationRead MoreMarine Mammals : Public Display And Research Essay1733 Words   |  7 Pagesfish nutrients the scientists determined that captive dolphins can acquire adequate nutrition if they are fed a combination of capelin and herring. This table represents the chemical pro file of their diet through fish. By feeding both of these fish to the dolphins it will ensure that they are getting balanced water, protein, and fat content. Another case study was done by Marine Mammals: Public Display and Research in 1994 to investigate the dolphins’ caloric requirements depending on their sex, ageRead MoreHow Animals Talk Like Humans1197 Words   |  5 Pagesare also used by many animals. Our habit to anthropomorphize other species has swayed many research projects that remain popularly believed. This principle of an existing human bias has debunked several studies including a famous study that came to the conclusion that pigs are able to express themselves in a way that allows them to interact coherently with humans. In fact, the humans being observed in the study had allowed themselves to apply a previous context on the pigs despite the animals actingRead MoreEssay on Bottlenose Dolphins2377 Words   |  10 PagesBottlenose Dolphins This essay is NOT formatted Bottlenose dolphins are among the most vocal of the nonhuman animals and exhibit remarkable development of the sound production and auditory mechanisms. This can be seen in audition, which is shown in the animal’s highly refined echolocation ability, and in tightly organized schools in which they live that are made up by sound communication. In testing the communication skills of dolphins, extensive studies have been done on vocal Read MoreA Case Of Nuturant Care : Adoption Of A Presumed Delphinus Calf By Bottlenose Dolphin3289 Words   |  14 PagesSHORT COMMUNICATION A novel case of nuturant care: Adoption of a presumed Delphinus calf by bottlenose dolphin (Tursiops truncatus) in Far North waters, New Zealand. CH Petersa* and KA Stockina aCoastal-Marine Research Group, Institute of Natural and Mathematical Sciences, Massey University, Auckland, New Zealand Worldwide inter-specific behavioural interactions in the order Cetacea are diverse and often complex. Epimelatic care can be described as nurturant or Succorant in nature. Adoption canRead MoreA Brief Note On The Scottish Coastal Waters1795 Words   |  8 Pagestime for the populations around Scotland to reproduce. Bottlenose dolphins (Tursiops truncatus) Tursiops truncatus can be seen inshore on the east and west coasts; on the north coast and in the northern isles in some occasion. The Moray Firth supports the bottlenose resident dolphins in the North Sea. This is a small population with around 195 individuals that lives along the Moray Firth down to the east coast (Firth of Forth). These dolphins are between 3 and 4 metres in length and are normally inRead MoreArgumentative Essay on the Pros and Cons of Dolphins Living in Captivity2012 Words   |  9 PagesArgumentative Essay on the Pros and Cons of Dolphins Living in Captivity versus the Pros and Cons of Dolphins Living in the Wild. The Common Bottlenose Dolphins (Tursiops Truncatus) are probably the most popular species of dolphins around. Coming under the order of Cetecea and the family of Delphinidae, the bottlenose dolphins are closely related to whales and are highly intelligent creatures (source 7). They are widely distributed around the world in the deep tropical and sub-tropical seas asRead MoreDrive Hunting in the Oceans2156 Words   |  9 Pagesof small whales, many dolphin species and some porpoises. They are killed in various manors, ranging from accidental ship strikes to the more morally controversial yearly drive hunts. As you may know nearly all cetaceans use some sort of sound production in order to navigate waters, communicate with other individuals and groups of their respective species as well as capture prey (Brownell et al., 2008). An example of this is the variety sounds produced by bottlenose dolphins (Tursiops truncatus)
