Humpback Whales Learn Hunting Techniques From Each Other
2013-04-26 08:03:57

April Flowers for redOrbit.com - Your Universe Online New research, led by the University of St. Andrews, has found humpback whales are able to pass on hunting techniques to each other, just as humans do. A new feeding technique has spread to 40 percent of a humpback whale population, the team discovered. Their findings have been published in a recent issue of Science. After herring stocks — their preferred food — crashed in the 1980s, a community of humpback whales off...

Seismic Ocean Surveys For Gas And Oil Could Kill 140,000 Marine Mammals
2013-04-18 08:52:07

Lawrence LeBlond for redOrbit.com - Your Universe Online Blasting sound waves through the ocean to the seafloor in search of fossil fuels may do more harm than good, according to environmentalists. But the US Department of Interior has been considering giving large oil and gas companies permission to do just that. According to estimates, scores of  marine mammals would be injured and possibly killed along the east coast if these companies follow through with their dangerous sonar...

Humuel Deer Population Resurges From Near Extinction
2013-04-16 13:45:31

Lee Rannals for redOrbit.com - Your Universe Online Researchers are reporting some rare good news in the world of animal conservation. Scientists from Cambridge University, the Wildlife Conservation Society and the Chilean National Forestry Commission (CONAF) say the endangered Huemul deer, native to Patagonia, is bouncing back from the brink of extinction. The Huemul is only found in the Latin American region, and the new report says the deer is experiencing a resurgence thanks to...

Detailing The Evolution Of Echolocation In River Dolphins
2013-04-05 13:51:23

Alan McStravick for redOrbit.com - Your Universe Online A new study by researchers from researchers at the Woods Hole Oceanographic Institute (WHOI) and Aarhus University in Denmark is focusing on one of the most endangered animal species currently known: the river dolphin. The Ganges river dolphin, after having diverged from other toothed whale species some 30 million years ago, is thought to be one of the oldest species of aquatic animals to employ the technique of echolocation, or...

Ice Age Was No Match For The Dwarf Baleen Whale
2013-04-05 05:29:28

Lee Rannals for redOrbit.com - Your Universe Online According to new research published in the journal Naturwissenschaften, the dwarf baleen whale lived well into the Ice Age. Researchers from New Zealand's University of Otago found that the fossil of a dwarf baleen whale from Northern California, or Herpetocetus, is thought to be the last survivor of the primitive baleen whale family, dating just 700,000 years old. Otago Department of Geology PhD student Robert Boessenecker said the...

Risk To Endangered Whales From Ship Traffic Off Southern California Analyzed In New Study
2013-03-26 13:12:04

Southwest Fisheries Science Center: NOAA Researchers have identified areas off southern California with high numbers of whales and assessed their risk from potentially deadly collisions with commercial ship traffic in a study released today in the scientific journal Conservation Biology. Scientists from NOAA Fisheries, the Marine Mammal Commission and Cascadia Research Collective analyzed data collected over seven years by NOAA on marine mammal and ecosystem research surveys in the...

Millions Of Prawns Wash Up On Beach
2013-03-22 21:17:50

Lee Rannals for redOrbit.com — Your Universe Online A beach in southern Chile is being overwhelmed by millions of stranded prawns that have taken up two miles worth of the coastline. According to a report by AFP, millions of the small prawns are covering a beach 300 miles south of Santiago, creating giant "red spots" on the sand. Fisherman said at first the red spots appeared just off the shore, but by Tuesday of this week the prawns had moved to land, and "millions" were...

Minke Whale Skeleton Found At Bottom Of Antarctic Ocean
2013-03-18 19:22:56

Lee Rannals for redOrbit.com — Your Universe Online Marine biologists reported in the journal Deep-Sea Research II: Topical Studies in Oceanography they have discovered a whale skeleton sitting on the ocean floor near Antarctica for the first time. Researchers said they made the discovery nearly a mile below the surface of the ocean in an undersea crater, offering some new insights into life in the sea depths. Until now, whale carcasses have never been studied in the Antarctic...

Bizarre Whale Strandings Not Due To Family Ties
2013-03-15 09:10:25

April Flowers for redOrbit.com - Your Universe Online Since the time of Aristotle, biologists have struggled to understand the reasons for mass strandings of whales and dolphins on beaches. Contrary to previous assumptions that whales follow each other onto the beach — and almost certain death — on account of familial ties, a new study from Oregon State University and the University of Auckland reveals that many unrelated individuals are present at each event. The findings...

Baleen Whale Teeth Entangle Tiny Prey
2013-03-14 16:15:40

Brett Smith for redOrbit.com - Your Universe Online Whether they hunt for food by opening their mouths while diving deep into the ocean or skimming along its surface, many whale species rely on their baleen teeth to filter tasty morsels from the mouthfuls of seawater they take in. According to Alexander Werth, a biology professor from Hampden-Sydney College in Virginia, no one has ever looked into the mechanism behind how the hairy substance actually traps food. “The standard...

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...
