Scientists at Georgetown University, the National Aquarium and the University of Queensland are the first to extract DNA from dolphin blow (breath exhalations). The researchers found that blow-sampling, which involves collecting exhalations from the blowholes of whales, dolphins and porpoises, could be developed as a less invasive method for DNA collection. Their findings are explained in the Aug. 25 edition of the online journal PLoS ONE in an article titled "Thar She Blows! A Novel Method...

Nearly 60 pilot whales have died after becoming stranded on a beach in northern New Zealand, conservation authorities reported Friday.There were 73 total whales discovered on the beach mid-morning and the Department of Conservation's Carolyn Smith said the whales most likely beached overnight, which is why so many died before rescue operations were launched.Of the 73 pilot whales, 15 have survived, but are reported to be in "poor condition." Volunteers are making another attempt to rescue the...

The evolutionary mystery of menopause is a step closer to being solved thanks to research on killer whales. A study by the Universities of Exeter and Cambridge has found a link between killer whales, pilot whales and humans "” the only three known species where females stop breeding relatively early in their lifespan. Despite very different social structures between the three species, the research shows that in each case females become increasingly genetically related to those...

Finless porpoises may be more endangered than previously thought. A new study of finless porpoises, a rare type of toothed whale, found that there are two species, not one, and they rarely intermingle. Scientists say that finless porpoises living in the fresh waters of China's Yangtze river are genetically unique, numbering fewer than 1000.  They warn that greater efforts must be made to prevent these animals. The whales inhabit a wide range of tropical and temperate waters...

Scientists are now saying that marine mammals are not only smarter than previously thought, but many also share several attributes once claimed to be exclusively human. Cetaceans, an order of more than 80 whales, dolphins and porpoises, have the ability to express self-awareness, suffering and have social cultures with high mental abilities, say marine biologists. If the notion is true that whales are intelligent and sentient beings, it would threaten to destroy the assumption that they are...

Park officials said Thursday that a 30-foot-long dead humpback whale washed ashore near Jones Beach State Park. According to George Gorman, spokesman for the Long Island region of the New York State Office of Parks, Recreation and Historic Recreation, the Riverhead Foundation for Marine Research and Preservation, a nonprofit marine life rescue organization, will make the determination of what to do with the whale's remains. The whale was discovered by parks' staff east of field 6 at Jones...

A new finding raises the possibility that commercial whaling may have taken a role breaking apart social groups of whales. Dr. Christian Ramp and colleagues of the Mingan Island Cetacean Study group based in St. Lambert, Canada have been studying whales since 1997 in the Gulf of St. Lawrence. The scientists are recording the movements of baleen whales including blue, fin, minke and humpback whales, adding to a set of data that stretch back 30 years. The team found that individual female...

The iPad might offer a new solution for scientists wishing to communicate with dolphins. Dolphin researcher Jack Kassewitz is using an iPad to interact with a 2-year-old dolphin named Merlin.  Kassewitz says this could potentially not only allow humans and dolphins to interact, but also be easily used as a universal translator for humans. "For several years, we've recognized that part of the problem in creating an artificial language between humans and dolphins has been the speed of...

Whales are remarkably diverse, with 84 living species of dramatically different sizes and more than 400 other species that have gone extinct, including some that lived partly on land. Why are there so many whale species, with so much diversity in body size? To answer that, UCLA evolutionary biologists and a colleague used molecular and computational techniques to look back 35 million years, when the ancestor of all living whales appeared, to analyze the evolutionary tempo of modern whale...

A group of conservationists and other experts said Sunday that whales and dolphins should get "human rights" to life and liberty because of growing evidence that they are highly intelligent beings. Participants at a conference at the University of Helsinki said more and more studies are showing the giant marine mammals have human-like self-awareness, an ability to communicate and organize complex societies, which makes them similar to great apes. "We affirm that all cetaceans as persons...

Marine Otter, Lontra feline
2012-12-28 15:09:41

The marine otter (Lontra feline) is a member of the weasel family, and can be found in South America. It prefers a habitat in rocky coastal areas, with a range that includes the entire coastline of Chile and extends to southern Peru and Argentina. It has been found on the Falkland Islands, but individuals here do not represent a constant population. Unlike other species of otter, the marine otter chooses to live near waters with high winds and swells. It may use caves and crevices as dens,...

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...

Mediterranean Monk Seal, Monachus monachus
2012-06-23 10:50:34

The Mediterranean monk seal (Monachus monachus) is a rare pinniped, or “fin-footed mammal” that can be found in areas of the Mediterranean Sea, as well as in the Atlantic waters of the Tropic of Cancer. Not much is known about the chosen land habitats of this seal, but until the 20th century, it could be seen relaxing or pup rearing on open beaches. It now dwells in underwater caves and caverns in order to escape human actions including tourism and expansion. The Mediterranean monk...

Profilicollis
2014-01-05 00:00:00

Profilicollis is a genus of acanthocephalan parasites that are found in crustaceans and shorebirds. Profilicollis parasites use decapod crustaceans as intermediate hosts and species of shorebirds as definitive hosts. The parasite first develops in mole crabs of North and South America. After it infects a mole crab, it becomes dormant until the crab is eaten by a suitable bird, such as a Surf scoter or Herring Gull. Once the parasite has passed through the stomach of the bird, it develops...

Chinese White Dolphin, Sousa chinensis chinensis (known as rare pink dolphins)
2012-05-25 11:45:30

The Chinese white dolphin, otherwise known as the Indo-Pacific humpback dolphin, is a species of humpback dolphin that can be found in the waters of Southeast Asia. When breeding, they will travel to the waters around South Africa to Australia.  There are currently two recognized subspecies of the Chinese white dolphin. The coloring of the Chinese white dolphin can vary due to age and location. When born, calves are actually black, but will change to grey, then pink with white spotting,...
