[ 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...

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...

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...

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...
