Humpback Whale Song Patterns Tracked Using Passive Acoustic Tracking
2013-04-30 07:17:28

Brett Smith for redOrbit.com - Your Universe Online Humpback whales are known for their songs that can be heard from miles away and new research from a team of American biologists has detailed the whales singing habits as they roam the feeding grounds of the northwest Atlantic. The study´s findings, which were published in the open access journal PLOS ONE, emphasize the usefulness of passive acoustics listening techniques in monitoring animal activity. “We have monitored...

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...

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...

New Species Of Whale Discovered In California Fossil Bed
2013-02-19 09:27:37

Lawrence LeBlond for redOrbit.com - Your Universe Online Fossil discoveries are nothing new. And finding new species is just as common. But when you find a fossil of an animal new to science, things start to get more interesting–especially when that discovery includes not one, but four new species from the same genus. This is exactly what occurred in the Laguna Canyon outcrop, a fossil bed unearthed during a highway construction project in California in 2000. The site, which was...

Deformed Dolphin Accepted By Sperm Whales
2013-01-25 19:47:06

Lee Rannals for redOrbit.com — Your Universe Online Despite their size, sperm whales have proven themselves to be nothing to fear, as reports come in about a group adopting a handicapped dolphin into their community. Scientists found a group of sperm whales near the Azores Islands, about 900 miles off the coast of Portugal, and an unlikely companion by their side: a dolphin with a spinal deformation. Science Magazine reported two behavioral ecologists from the Leibniz...

New fossil reveals history of last-living marine mammals to eat only aquatic plants A new fossil discovered in Tunisia represents the oldest known ancestor of modern-day sea cows, supporting the African origins of these marine mammals. The find is described in research published January 16 in the open access journal PLOS ONE by Julien Benoit and colleagues from the University of Science and Technology in Montpellier, France. Some fossils of sea cow ancestors have been found in Jamaica,...

Threatened Pilot Whales Swim As A Team
2012-11-24 07:27:08

redOrbit Staff & Wire Reports - Your Universe Online When long-finned pilot whales sense the presence of a potential danger, they use synchronized swimming as a defense mechanism, an international team of scientists has discovered. Scientists from the University of Aberdeen in Scotland, the Doñana Biological Station (CSIC) and the Conservation, Information and Study on Cetaceans (CIRCE) studied the behavior of the approximately 300 members of the Globicephala melas...

Author, inspired by the splendor of whales, describes spiritual interactions with animals TRINITY, Newfoundland (PRWEB) August 13, 2012 Some of the most passionate activists are those who fight for the lives of whales and dolphins, such as on the Animal Planet television series. Finding majesty and intelligence in whales — some of nature´s most fascinating creatures — biophysical research scientist Peter Beamish wrote “Dancing with Nature” (published by Trafford...

False killer whales focus echolocation clicks Hunting in the ocean's murky depths, vision is of little use, so toothed whales and dolphins (odontocetes) rely on echolocation to locate tasty morsels with incredible precision. Laura Kloepper from the University of Hawaii, USA, explains that odontocetes produce their distinctive echolocation clicks in nasal structures in the forehead and broadcast them through a fat-filled acoustic lens, called the melon. 'Studies by other people showed...

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...
