Five Distinct Humpback Whale Populations Identified In North Pacific Ocean
2013-12-04 19:40:46

Lee Rannals for redOrbit.com – Your Universe Online A new genetic study shows there are five distinct humpback whale populations in the North Pacific Ocean. There is currently a proposal to try and designate North Pacific humpbacks as a single distinct population segment, which could ultimately threaten the species’ endangered status. Humpback whales are listed as endangered in the US under the Endangered Species Act, but the species has recently been downlisted by the...

Killer Whales Use Stealth Approach When Hunting Prey
2013-12-04 04:57:23

[ Watch the Video: Stealthy Tactics Used By Orca To Catch Their Prey ] redOrbit Staff & Wire Reports - Your Universe Online Newly discovered evidence that killer whales can hunt marine mammals during the nighttime has led scientists to suggest that the creatures can use their hearing to help locate prey, according to research presented at the 166th Meeting of the Acoustical Society of America (ASA). For example, the study authors said that the whales eavesdrop on male harbor...

Unprecedented Dolphin Die Off Witnessed Along Eastern US Coast
2013-11-10 06:34:01

Alan McStravick for redOrbit.com - Your Universe Online The National Oceanic and Atmospheric Administration (NOAA) announced unsettling and unfortunate news this week centered on the bottlenose dolphin and Cetacean populations on the east coast of the United States. We are witnessing the most unprecedented stranding and die-off of these creatures in our recorded history. The last major incidence of stranding and die-off of these populations occurred in 1987-88 and was responsible for an...

Just Like People, No Two Bottlenose Dolphins Are Genetically Alike
2013-11-05 08:35:44

April Flowers for redOrbit.com - Your Universe Online The most common and well-known of their kind, bottlenose dolphins are famous for their roles in movies, television and water parks everywhere. And to the layperson's eye, one bottlenose dolphin might not look any different from another. When you look closer, however, perhaps genetically, there are telltale differences in these creatures. A new study, published in the Journal of Heredity, focused on groups of bottlenose dolphins that...

Bottom-Feeding Observed In Gulf Of Maine Humpback Whales
2013-10-31 07:35:24

April Flowers for redOrbit.com - Your Universe Online Humpback whales have exhibited a complex set of feeding techniques, including "trapping" krill and other prey within bubble nets produced by the whales and gulping up to two-thirds their weight in prey-laden water. A new study, published in Marine Mammal Science, confirms that humpback whales in the southern Gulf of Maine are spending more feeding time on the ocean floor than in any of these other typical feeding behaviors. These...

Dolphin Study Provides Insight Into History, Conservation Of Species
2013-10-30 10:15:45

April Flowers for redOrbit.com - Your Universe Online A research team from Nanjing Normal University and BGI has completed original genomic research on the Yangtze River dolphin (Lipotes vexillifer), commonly known as Baiji. The study, published in Nature Communications, provides new insight into the genetic and evolutionary adaptations of dolphins and valuable resources for the conservation of mammals, and in particular, of cetaceans. The baiji has been nicknamed "goddess of the...

New Humpback Dolphin Species
2013-10-30 08:25:36

[ Watch the Video: There's A New Dolphin In The Family ] April Flowers for redOrbit.com - Your Universe Online A team of researchers, led by the Wildlife Conservation Society (WCS) and the American Museum of Natural History, have discovered a previously unknown species of humpback dolphin swimming off the coast of northern Australia. The research team used both physical features and genetic data to study the evolutionary history of this family of marine mammals in order to determine...

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...

Algorithm used in music retrieval systems applied to help identify dolphin whistles The same algorithm used to find tunes in music retrieval systems has been successfully applied in identifying the signature whistles of dolphins, affording a new time-saving device for research into the world of dolphin communication. Bottlenose dolphins, in particular, recognize each other by name: the sound of each animal's "signature" whistle, which each dolphin develops at a young age. Bottlenose...

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...
