Bats And Whales Share Echolocation Success Story
2013-10-30 04:37:49

[ Watch the Video: Echolocation Frequencies Similar In Bats And Whales ] April Flowers for redOrbit.com - Your Universe Online What could a 50 ton whale and a one gram bat have in common? They share a success story - both have developed the ability to use echolocation, a type of biological sonar, for hunting. A new study from Aarhus University and the University of Southern Denmark reveals that the biosonar of toothed whales and bats share surprisingly many similarities - even though...

How Mice And Rats Developed A Unique Masticatory Apparatus Making Them Evolutionary Champions
2013-10-28 13:02:40

European Synchrotron Radiation Facility The subfamily of rodents known as Murinae (mice, rats, etc.), which first appeared in Asia 12 million years ago, spread across the entire Old World (Eurasia, Africa, Australia) in less than 2 million years, a remarkably fast rate. Researchers have long suspected that one of the reasons for their evolutionary success is related to their unique masticatory apparatus. Now, researchers have used the brilliant X-ray beams produced at the European...

Eastern Steller Sea Lions Delisted As Endangered Species By NOAA
2013-10-28 09:03:40

Lawrence LeBlond for redOrbit.com - Your Universe Online Not since 1994 has the National Oceanic and Atmospheric Administration (NOAA) removed an animal from the Endangered Species Act (ESA) due to effective recovery efforts. The eastern North Pacific gray whale was taken off the list of threatened and endangered species nearly 20 years ago after evidence was found that these marine mammals had recovered to near their estimated original population size and were no longer in danger of...

Scientists Study Genetics Of Blue Whale Immune Systems
2013-10-10 12:57:41

Brett Smith for redOrbit.com – Your Universe Online The immune system of blue whales living in the Gulf of Mexico is as good as that of humans and other terrestrial mammals. According to researchers from the National Polytechnic Institute (IPN) in Mexico and the University of Guelph in Canada, a genetic analysis revealed the whale species is healthy and could withstand an outbreak of bacteria or fungi. Jorge Ortega Reyes, head of the research conducted at the National School of...

Did A Dexterous Hand Or An Agile Foot Evolve First
2013-10-07 11:16:58

RIKEN Resolving a long-standing mystery in human evolution, new research from the RIKEN Brain Science Institute indicates that early hominids developed finger dexterity and tool use ability before the development of bipedal locomotion. Combining monkey and human behavior, brain imaging, and fossil evidence, a research team led by neurobiologist Dr. Atsushi Iriki and including Dr. Gen Suwa, an anthropologist from the University of Tokyo Museum, have overturned the common assumption that...

Genetics Define Separate Groups And Subspecies Of The Bryde's Whale
2013-10-04 04:42:24

April Flowers for redOrbit.com - Your Universe Online Researchers attempting to define populations of a medium-sized and poorly understood baleen whale say that saving the whales often means knowing - sometimes on a genetic level - one group of whales from another. A group of scientists from Wildlife Conservation Society, the American Museum of Natural History, Columbia University, NOAA, and other groups are working to define separate groups and subspecies of the Bryde's whale, which are...

New Humpback Feeding Technique
2013-09-26 15:43:14

Brett Smith for redOrbit.com - Your Universe Online Using underwater “critter cams” and tagging techniques, a team of marine biologists from the National Oceanic and Atmospheric Administration (NOAA) was able to confirm a unique humpback whale feeding technique performed along the ocean floor, according to their report in the journal Marine Mammal Science. Based on observations of whales off the coast of Massachusetts, the report revealed that humpbacks use three distinct feeding...

Whale Earwax Helps Understand History
2013-09-17 09:55:54

[ Watch the Video: Blue Whale Earwax Tells A Tale Of A Lifetime ] Brett Smith for redOrbit.com - Your Universe Online Earplugs made of wax and fats are common to blue and other large whales and resemble the waxy buildup in our own ears – except on a much, much larger scale. To learn more about the history of individual whales, marine biologists from Baylor University and the Natural Museum of History have developed a unique method for analyzing these earplugs. The technique reveals...

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...

Dall’s Porpoise, Phocoenoides dalliz
2013-08-29 10:15:35

Dall’s porpoise (Phocoenoides dalliz) can only be found in the North Pacific, with a range that includes the Sea of Japan and the Okhotsk and Bering Seas. This range extends to southern California in the east and to the southern waters of Japan in the west. When normal weather patterns change and waters become colder, this species can be found in in Baja, California, specifically in Scammon's Lagoon, and strays can occasionally be found in the Chukchi Sea. It prefers to reside in cold...

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...
