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...

Redescription Of Dolphin Skull Sheds Light On Their Origins And Evolution
2014-05-08 03:04:46

[ Watch the Video: CT Image Of The Skull Of Oldest Known Dolphin ] Society of Vertebrate Paleontology Dolphins are the most diverse family of living marine mammals and include species such as the bottlenose dolphin and the killer whale. However, their early evolution and fossil record has been steeped in mystery due to lack of good specimens. 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...

Will Continue to Educate Consumers About The Deceptive "Dolphin-Safe" Label WASHINGTON, April 9, 2014 /PRNewswire-USNewswire/ -- The Campaign for Eco-Safe Tuna today praised the Government of Mexico's decision to continue its decades-long effort to promote a more sustainable approach to tuna fishing and adequately ensure consumers that no dolphins were harmed in the capture of tuna bearing the "dolphin-safe" label. Yesterday's filing of its first written submission in the Article...

Tracking Ecology Of sperm Whales Through Stomach Contents
2014-04-07 07:48:42

University of Massachusetts at Amherst In the largest regional study of its type to date, marine ecologists offer better understanding of the feeding ecologies of 2 very rare sperm whale species in waters off the southeast US coast, adding baseline data they say are important as climate change, fishing and pollution alters the animals' environment and food sources. “Understanding what resources support populations of these incredibly rare animals is important to conservation,”...

Japan Loses Against Australia, UN In Fight To Continue Annual Whaling
2014-03-31 14:48:05

Brett Smith for redOrbit.com - Your Universe Online Japan’s highly-contentious whaling campaign experienced a major setback on Monday when a United Nations court ruled that the island nation could no longer continue its annual whale hunt in the waters around Antarctica. The International Court of Justice ruled in favor of Australia, which had sued Japan and rejected that country’s argument that the whaling has been conducted mainly for scientific reasons. “The court concludes,...

Whales dive to nearly 2 miles depth, for over 2 hours Scientists monitored Cuvier's beaked whales' record-breaking dives to depths of nearly two miles below the ocean surface and some dives lasted for over two hours, according to results published March 26, 2014, in the open access journal PLOS ONE by Gregory Schorr from Cascadia Research Collective and colleagues. Distributed throughout the world's oceans, the Cuvier's beaked whales' frequent dives deep into the ocean make them...

Skin Bacterial Communities Similar Across Humpback Whale Populations
2014-03-27 08:48:25

Lawrence LeBlond for redOrbit.com - Your Universe Online The omnipresence of bacteria in the environment as well as on our own skin makes research on how they affect human health an important topic in the scientific and medical community. But little is known about the identity or function of skin bacteria that is found on other mammals. Researchers, led by microbiologist Amy Apprill from the Woods Hole Oceanographic Institution, have conducted a widespread study on the bacterial...

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...

Southern Right Whale, Eubalaena australis
2013-06-22 16:13:36

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...
