The Origins Of Whale Teeth
2013-02-20 10:30:22

April Flowers for redOrbit.com - Your Universe Online Although whales are mammals, they do not resemble any of the mammals surrounding us on land and have a unique evolutionary history. Whales have a triangular fluke for a tail, and they have no (visible) hind legs or body hair. One of the strangest differences between whales and their terrestrial cousins, however, is in the whale's mouth. Whale teeth are simpler and more "peg like" than those of other mammals. A new study...

Cetology
2013-10-02 11:21:29

Cetology is a branch of marine mammal science that studies about eighty species of dolphins, whales, and porpoise, all of which are classified within the Cetacea order. Cetologists, who practice cetology, work to understand the distribution, development, behavior, and other aspects of cetaceans. The study of cetaceans began in the Classical era. About 2,300 years ago, Aristotle documented details about some cetacean species, calling them mammals, while traveling on the Aegean Sea with...

North Atlantic Right Whale, Eubalaena glacialis
2013-08-26 11:17:56

The North Atlantic right whale (Eubalaena glacialis), also known as the black right whale or the northern right whale, is one of three right whales in the Eubalaena genus. It can be found in a small population of about 396 individuals in the western North Atlantic. If it does occur in the eastern North Atlantic, experts assert that it only numbers in the tens, making it nearly extinct in that area. This species migrates into the western North Atlantic to feed in the spring, summer, and fall...

During the summer, it can be found in the Southern Ocean, possibly near Antarctica. During the winter, populations disperse into many warmer areas to breed, including waters near Chile, Argentina, New Zealand, South Africa, Peru, Namibia, Brazil, Australia, and Madagascar, among other areas.

Crabeater Seal, Lobodon carcinophagus
2012-06-26 14:40:11

The crabeater seal (Lobodon carcinophagus) is a true seal that can be found around the whole of Antarctica. Its range also includes small areas in South America, New Zealand, Africa, and Australia. It resides on the pack ice zone for the entire year, even as it shifts seasonally, and prefers to stay in the continental shelf area in water with a depth of less than 1,968 feet. Because the populations are so wide spread and are sufficiently mixed, there have been no subspecies found. Because...
