Genetic Research Reveals Three Unique Humpback Whale Subspecies
2014-05-21 09:55:22

Gerard LeBlond for redorbit.com - Your Universe Online The humpback whale is a large baleen whale that can weigh as much as 40 tons and can be up to 50 feet long. The female breeds and births its calf in sub-tropical waters during the winter and migrates to polar regions to feed in the summer. The humpback inhabits every ocean in the world except the Mediterranean sea. Its behavior includes leaping out of the water and slapping the water’s surface with its tail and long pectoral...

Hearing Tested In Bristol Bay Beluga Whale Population
2014-05-15 03:52:01

Woods Hole Oceanographic Institution The ocean is an increasingly industrialized space. Shipping, fishing, and recreational vessels, oil and gas exploration and other human activities all increase noise levels in the ocean and make it more difficult for marine mammals to hear and potentially diminish their range of hearing. “Hearing is the main way marine mammals find their way around the ocean,” said Aran Mooney, a biologist at Woods Hole Oceanographic Institution (WHOI). It’s...

A new paper published in latest issue of the Journal of Vertebrate Paleontology re-describes the oldest species of dolphin with a new name:...

Whales Hear Us More Than We Realize
2014-05-02 03:56:58

Tom Rickey, Pacific Northwest National Laboratory Killer whales and other marine mammals likely hear sonar signals more than we've known. That's because commercially available sonar systems, which are designed to create signals beyond the range of hearing of such animals, also emit signals known to be within their hearing range, scientists have discovered. The sound is likely very soft and audible only when the animals are within a few hundred meters of the source, say the authors...

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...

The southern right whale (Eubalaena australis) is a species of baleen whale that can be found in different regions in the summer and winter seasons. 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. Right whales were first classified by Carolus...

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...
