New Study Finds Ocean Ecosystems Naturally Engineered By Whales
2014-07-03 14:58:31

Brett Smith for redOrbit.com - Your Universe Online Whales have often been viewed as the lonely nomads of the seas, but a new report has found that these large mammals are actually great engineers of marine ecosystems. Published in Frontiers in Ecology and the Environment, the new study reviewed several decades of research on whales from around the world and found they play a powerful and positive role with respect to ocean function, global carbon storage, and ecosystem productivity....

Hearing Tested In Bristol Bay Beluga Whale Population
2014-05-15 03:52:01

Woods Hole Oceanographic Institution The ocean is an increasingly industrialized space. Shipping, fishing, and recreational vessels, oil and gas exploration and other human activities all increase noise levels in the ocean and make it more difficult for marine mammals to hear and potentially diminish their range of hearing. “Hearing is the main way marine mammals find their way around the ocean,” said Aran Mooney, a biologist at Woods Hole Oceanographic Institution (WHOI). It’s...

Semirostrum ceruttii

Brett Smith for redOrbit.com - Your Universe Online Researchers from Yale University have announced the discovery of a new species of ancient porpoise with a massive underbite. According to a report published in the journal Current Biology, the newly discovered cetacean had a jaw that extended nearly 2.8 feet – a unique feature that was probably used to probe to seafloor for something to eat, the study team said. "The extinct porpoise is a bizarre new animal, with the mandible...

Ships On A Collision Course With Whales In The Bering Strait
2014-02-28 10:42:59

Brett Smith for redOrbit.com - Your Universe Online Diminishing sea ice in Arctic waters has opened up new lanes of aquatic traffic and new research from the University of Washington has found that when it comes to the Bering Strait – whales and commercial ships are on a collision course. The new research, presented at the Ocean Sciences meeting in Honolulu on Wednesday, is based on three years of underwater recordings in the Bering Strait. UW research Kate Stafford found Arctic...

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...

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...

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...

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...

Indo-Pacific Bottlenose Dolphin, Tursiops aduncus
2013-09-19 11:24:25

The Indo-Pacific bottlenose dolphin (Tursiops aduncus) is one of three recognized species of bottlenose dolphin that can be found in the waters near southern Australia, South China, and India. Its range also includes the Red Sea and the eastern coastal areas of Africa. All bottlenose dolphins were classified as one species, the common bottlenose dolphin or T. truncates, until 1998 when the Indo-Pacific bottlenose dolphin was found to be distinct. This species is distinct from other bottlenose...

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...

Blainville's Beaked Whale, Mesoplodon densirostris
2013-08-17 13:31:16

Blainville’s beaked whale (Mesoplodon densirostris), also known as the dense-beaked whale, can be found in a large range that includes the warm and tropical waters of all oceans. It prefers to reside at depths between 1,600 and 3,000 feet and does not migrate. This species received its common name from Blainville, the man who classified it as Delphinus densirostris after studying a description of a piece of one individual’s nose located in the Paris Museum. In 1846, John Edward Gray...

Hourglass Dolphin, Lagenorhynchus cruciger
2013-08-16 10:45:47

The hourglass dolphin (Lagenorhynchus cruciger) is a rare species that can be found in Antarctic and subAntarctic waters. Most sightings of this species have been made in the southern waters near the Shetland Islands, off the coast of Tierra del Fuego, Argentina, and in the southern waters near New Zealand. It is thought that this dolphin does not congregate in large numbers in any area of its circumpolar range. Qouy and Galmard first recognized the hourglass dolphin as a new species in...
