Essay: cetacean Evolution of Cetacean The 1996 winter issue of Pacific Discovery; a publication of the California Academy of Sciences focused largely on whales and in her article about the origins and early evolution of whales, Elizabeth Culotta covers ecology and evolution. Culotta discusses tremendous development in evolution of whales in the last few years. No less than 3 new forms-Rodhocetus, Ambulocetus and Pakicetus-have been discovered to fill the missing gaps between the present day whales and their terrestrial predecessors-mesonychid carnivores that existed 60 million years ago in the Eocene epoch. Paleontologists have along the way learned much more regarding the evolution as well as the relative timing of the adaptation of ears, skulls, jaws, limbs and backbones for life particularly in the open sea. Culotta argues that fossil relatives of existing whales are identified not by specialized swimming and great size but instead by aspects of their teeth and skull shared only with existing whales(Padian,1997).

Biogeography of bottlenosed dolphins

...of bottlenose dolphins, thus are critical to the health of the organism. EVOLUTIONARY HISTORY The suborder Odontoceti has been reported to appear in early Oligocene, radiating dramatically in to the Miocene. The fossil records of early cetaceans indicate the transition from an intermediate land ancestor to a presently extinct aquatic form termed archaeocetes. Data gathered from brain size studies or encephalization records from the fossils suggest significant changes in brain size during Oligocene, characterized by the transition from archaeocetes to early odontocetes. The diversity in the morphological and behavioral characters of the genus Tursiops is limited. The pattern of diversity within a taxonomic rank is...

Marine Dolphins

...Marine Dolphins Introduction Dolphins are known as small cetaceans, though some dolphins are quite large. They can mature up to a length of over 20 feet. The biological classification of dolphins is as follows: Kingdom Animalia Phylum Chordata Class Mammalia Order Cetacea Sub-order Odontoceti Family Delphinidae Genus Delphinus Species delphis From the classification, the scientific name for dolphin is Delphinus delphis. Dolphins have their habitats in oceans, seas and major rivers. They have become specialized to their different ecological niche that they occupy. Dolphins are exclusively carnivorous. Some feed exclusively on fish or cephalopods. Cephalopod is a class of marine that includes cuttlefish and octopus. Other...

Right Whales in today's environment

...Right Whales in Today’s Environment Scientists are still uncertain about the exact origin of right whales, but they are certain that right whales have existed much longer than human beings. Right whales are classified as marine mammals. They belong to the ‘cetaceans’ group; the term cetacean means ‘sea monster’ or ‘whale’. Right whales, similar to the North Atlantic right whale, are one of the rarest marine mammals (Knowlton & Kraus 193). They are slow swimmers and usually perform short shallow dive successively before going under water. They normally move from place to place in small numbers or on their own. They also give out soft sounds that could be their means of communication. Most of these huge...

Evolution of Color Vision in Mammals

...evolution in the sea. The visual acuity and sensitivities to light spectrum have provided a way for humans to understand how dolphins see color. For instance, dolphins did not evolve to possess any functional cones like primates and marsupials, which have rendered them color blind (Lazareva et al 29). Dolphins lack any functional S-opsin for short wave light sensing. This is similar to the dichromatic nature of distant pinnipeds and cetaceans, as well as being an adaptive mechanism. However, this result of evolution in the loss of the S-cone cannot be explained rationally. This is actually a paradoxical situation since the open waters of the ocean possess blue light with other wavelengths being scattered or absorbed. In...

The Current Conservation Status of a Group of Marine Vertebrates

...CRITICAL REVIEW OF THE CURRENT CONSERVATION STATUS OF A GROUP OF MARINE VERTEBRATES A group of marine vertebrates, which are actually mammals called whales, belonging to the order cetaceans, have since been men's inspiration to be passionate with the natural world of the deep. Most people believed that cannibalizing members of such group of marine mammals is a taboo. But, for some, catching, butchering, and selling this marine mammal is profitable at the least cost. This is despite the limitations set by the International Whaling Commission and some environmental watchers (Stoett, 1997). Body Global 'ecopolitics' on 'whaling' have intensified. This was driven not merely by negative foresights on the eventuality of...

Dolphins Facts and Information

...its offspring and communicated through underwater sounds” (Wik, 2002). Aside from Aristotle, Greek writers have also mentioned dolphins in their stories, often portraying them as friendly creatures of the sea. In 75 A.D., Plutarch wrote about the story of Korianos who begged for a dolphin’s life and was later saved by it during a shipwreck. On the other hand, Greek poet Oppian narrated how dolphins help fishermen in catching fishes by pushing them into their nets (Eyers, 2011). According to Dr. Alexandros Frantzis, head of the The Pelagos Cetacean Research Institute, "the image of dolphins then, like nowadays probably had some relaxing effect toward humans and was probably a symbol of the harmony and the health of the...

Japans right to whaling is legally justified

...continues its whaling, which is undertaken by the Institute of Cetacean Research. Once the whales are hunted for scientific reasons (as claimed), they are then sold as food, which is allowed under the IWC directives, even though a majority of the IWC members opposes the provision (Taylor, 2010). The so-called scientific hunts are an issue of debate between anti and pro-whaling nations and those opposing whaling claim that scientific program of Japanese government related to whales is unnecessary and is primarily a mask that helps it continue with commercial hunting operations (Briggs, 2007). In retaliation, Japan continues to maintain the sustainability of whaling and necessity of effective management of whales and...

...of human species. Currently, the population of these is decreasing. The average temperature in winter is as low as -40 degrees Celsius. Before the current time, temperature recordings were as low as -68 degrees Celsius. Going by the current rate, the Arctic Circle is dropping from what it is supposed to be; cold, to a warmer climate. This is an effect of the global warming. The ice is melting thus the degree of coldness is decreasing. Animals residing in the Arctic Circle include the Arctic hare, Lemming, muskox, caribou. These are herbivores that are preyed on by the fox and the wolf. The common land animal is the polar bear, which prefers to hunt for marine food. Marine mammals include seals, walrus, cetacean-baleen...
