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...

Genes Show How Whales Evolved For Oceans
2013-11-25 10:54:21

Brett Smith for redOrbit.com - Your Universe Online Approximately 54 million years ago, whales and other cetaceans diverged from land-dwelling mammals and gradually evolved to live a productive life at sea. A new study published in the journal Nature Genetics on Sunday revealed genetic evidence of how whales evolved the ability to dive deep into the ocean for long periods of time and how they developed a specialized feeding system that uses baleen instead of teeth. In the study, a...

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...

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 Finless Porpoises Hear In the Yangtze
2013-10-21 13:40:33

Brett Smith for redOrbit.com - Your Universe Online The Yangtze is the longest river in Asia and it’s also one of the busiest. The amount of traffic in the Chinese waterway can pose a significant problem for animals living there, and a new study by scientists from the Woods Hole Oceanographic Institution (WHOI) in Massachusetts has found that the Yangtze’s finless porpoises may have trouble using sound to negotiate their way through the bustling waters. With an estimated 1,000 animals...

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...

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...

Mass Stranding Of Melon-headed Whales Attributed To Sonar Mapping
2013-09-25 15:48:07

Wildlife Conservation Society An independent scientific review panel has concluded that the mass stranding of approximately 100 melon-headed whales in the Loza Lagoon system in northwest Madagascar in 2008 was primarily triggered by acoustic stimuli, more specifically, a multi-beam echosounder system operated by a survey vessel contracted by ExxonMobil Exploration and Production (Northern Madagascar) Limited. In response to the event and with assistance from IFAW, WCS led an...

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...

Giglioli’s Whale, Amphiptera pacifica
2013-08-19 13:14:53

The Giglioli’s Whale was discovered by zoologist Enrico Hillyer Giglioli on September 4, 1867, 1200 miles of the coast of Chile. He did not recognize the whale as any known species. It was observed for 15 minutes swimming close to his ship. Giglioli described the whale as being 60 feet long with an elongated body and having two dorsal fins 6.5 feet apart. No other known species of whale has two dorsal fins. It had long sickle-shaped flippers and lacked furrows under the throat....

2013-06-22 16:21:07

The Antarctic minke whale (Balaenoptera bonaerensis), also known as the southern minke whale, is one of two minke whales within the Mysticeti suborder, which contains baleen and rorqual whales. It can be found in every ocean in the southern hemisphere, residing in Antarctic waters in the summer months and northern waters in the winter months, where its range overlaps that the smaller common minke whale. The Antarctic minke whale was once classified with the common minke whale as a single...
