The conservation strategies directed at habitat preservation of the organism are recommended. BIOGEOGRAPHY OF BOTTLENOSE DOLPHINS INTRODUCTION Bottlenose dolphins belong to the order Cetacea, the term derived from Greek word ketos meaning whale. The order includes large aquatic mammals with forelimbs modified into flippers, a horizontally flattened tail, lacking hind limbs and with one or two nostrils. The order includes the suborders Odontoceti (toothed whales) and Mysticeti (baleen whales). Most Dolphins are included in the family Delphinidae, belonging to suborder Odontoceti, including the bottlenose Dolphin or genus Tursiops. The genera Tursiops (derived from Latin word Tursio meaning Dolphin or Dolphin like), has been further classified to include two species on the basis of biochemical and genetic studies: common bottlenose dolphin or T. truncatus and the Indopacific bottlenose dolphin or T. aduncus (Rice, 18). ...
The biogeography of an organism provides significant information regarding its evolutionary history and adaptation. Thus biogeography can be considered to include the spatial as well as temporal distribution of an organism. The common bottlenose dolphin T.trucatus enjoys worldwide distribution including tropical and temperate, inshore, coastal, shelf and oceanic areas (Reynolds et al., 12), except the polar region, northward of 45?, though they do occurs far as 62?N7?W in northern Europe. Found rarely in Baltic Sea and vagrant in Newfoundland and Norway, the species is present is as yet uncertain in other areas. The author aims to present in the current paper an account of the biogeography of the common bottlenose dolphin or T. truncatus; along with the evolutionary history of the organism on the basis of fossil records and the threat to conservation programs for the organism specially those relating to its biogeography. BIOGEOGRAPHY Figure 1 The major distribution areas of common bottlenose dolphin (figure 1) include the western margins of North Atlantic where the coastal forms occur within a distance of 5km from the land and in bays and estuaries (Mead and Potter, 165). The offshore forms occur within 200-2000m range along the shelf break in regions north and north east to Georges bank (Kenney, 369); and in the Scotian shelf; with the distribution of the two forms overlapping in some zones. The coastal forms are prevalent throughout the year continuously along the North Carolina to Texas (Mead and Potter, 165). In southeastern US they also occur as communities exhibiting specific association patterns and individual home ranges. In the eastern Pacific region, T. truncatus occurs in the ...Download file to see next pagesRead More

Should Dolphins be Considered Persons

...? Should dolphins be considered persons Insert Personhood is connected with a variety of theoretical issues with the most significant being that persons get better treatment that nonpersons. Although the terms human and person are used interchangeably as synonyms on a daily basis, the two words have a different meaning form a philosophical perspective. The word human is a scientific concept with reference to members of the biological category Homo sapiens. On the other hand, the word person refers to a combination of complex traits by which we define intelligence, self-consciousness and freewill (White 2007). According to recent research by scientists, dolphins have proven to possess sophisticated nervous...

Marine Dolphins

...a varied diet that may include lobsters, crabs, squid, shrimps and fish. The dolphins bear live young ones and feed the young ones with milk. Many marine dolphins are facing extinction due to human activities, but some laws have been formulated to protect their existence (Nakamura 64). Types of Marine Dolphins The major types of marine dolphins are pacific bottlenose, rough-toothed, spotted dolphin and spinner dolphin. The bottlenose dolphins are the most famous of all cetacean species. The scientific name for bottlenose dolphin is Tursiops truncatus....

Massive Extinction of Dolphins

... Massive extinction of dolphins Introduction A century and a half ago, Henry David Thoreau wrote down that the wild is conservation of the world. Mankind is not supposed to be living in human societies that enclose small conserved ecosystems inside them. Human societies are supposed to be sustained in small populaces’ reserves inside affiliated ecosystems. According to Aldo Leopold, “his visions are more than fifty years old and they are still cut trail for humankind (Miller 113).” At the same time, he still stands as one of the greatest conservator during the 1900’s. Currently, we are residing in what preservation biologists refer to as the Holocene extinction occurrence. This is the sixth worldwide massive extinction even... in the...

Dolphins are human

...Dolphins are human Experts in conservation and philosophy believe that dolphins are brilliant and intelligent to supportthe ethical or moral considerations as persons or humans. When people identify and recognize the rights of dolphins, it would imply an end to their captivity. This argument is based on assertion that dolphins have intricate brain and human or person like level of self awareness. This has led experts in philosophy and conservation to conclude that dolphins are humans. Thomas White notes that dolphins should be awarded an equal treatment same to human beings. This is in regard to scientific evidence which supports the...

... Number of the Biome: Tropical Savanna 2. Characteristics of Physical Environment: Climate: A tropical wet and dry climate predominates. Mean monthly temperatures are at or above 64° F and annual precipitation averages between 30 and 50 inches. During the dry season, less than 4 inches a month are received. The dry season is associated with the low sun period. Soil: Soils vary according to bedrock and edaphic conditions. In general, however, laterization is the dominant soil-forming process and low fertility oxisols can be expected. Landforms: Savannas exist in all tropical climatic regions. They cover some 20% of the worlds land surface and most of the savanna regions are less than 500 m above sea level. There are 3 kinds... Number of the...

Dolphins Facts and Information

...on land some ten million years ago. According to scientists, dolphins’ skeleton show that its front flippers is a modified form of hands and the two unattached bones behind its ribcage are pelvic girdles, to which hind limbs once attached (MacGillivray, 2000). Interestingly, dolphins are known for its complex communication which consists of their call ranges, cognitive skills, and ability to modify signals through vocal learning. A study by Janik (2000) revealed how bottlenose dolphin uses whistles that could reach over 580 meters to interact one another. Aside from this, dolphins are known to communicate through sonar which interest auditory...

A study by Janik (2000) revealed how bottlenose dolphins use whistles that could reach over 580 meters to interact one another. Aside from this, dolphins are known to communicate through sonar which interests auditory researchers, acoustical physics, and even military scientists. In his book “The Sonar of Dolphins”, Au (1993) documented the abilities to echolocate which means it can explore the depths of the ocean...

...Dolphins I. The Global Economy in the Post World War II Period There are a great number of elements that contributed to the United s global hegemony in the post World War II period. In large degree one must consider the nature of World War II warfare. While the United States actively participated in the war, outside of the Pearl Harbor invasion, there was no fighting that occurred in the United States; this is contrasted with significant destruction to factories and infrastructure that occurred throughout Europe and substantial parts of Asia (Boyer). These factories largely contributed to American economic prosperity and expansion. Another factor was that pent-up consumer spending from the Great Depression and war...

...Dolphins Introduction Dolphins are part of toothed whales’ family that includes pilot whales and orcas. They belong to the sub-order odontocetes of the order cetacea and are classified under the biggest and the most diverse family of this order – the family Delphinidae, which comprises more than thirty existing species (, 3). They are commonly called small cetaceans as a group, although some of them are fairly big, reaching lengths of 20 feet and above. Dolphins are usually gray in color and their backs are darker than other parts of their bodies. They have a distinctive beak and their teeth have the shape of a cone. Generally, male dolphins are bigger than...
