Brett Smith for RedOrbit.com The grisly deaths of two dolphins at a Swiss theme park is shrouded in mystery and accusations as investigators attempt to determine what exactly killed Shadow and Chelmers, two of the park´s biggest aquatic attractions. According to various media reports, the dolphins died five days apart in November of last year while swimming in their tank at Connyland Marine Park in Switzerland. Their deaths occurred shortly after the space next to their tanks was...

Unique Whistles Allow Dolphins To Greet Each Other
2012-03-01 05:45:52

Marine biologists have discovered that bottlenose dolphins use whistles to greet other members of their species. The researchers in Scotland said they made recordings of dolphins swimming in St. Andrews Bay in the summers of 2003 and 2004 by using hydrophones. They said when the group of dolphins met up, they swapped whistles that outwardly sounded the same. "The whistle exchange is more of a greeting ceremony that communicates a friendly intention and is perhaps not needed to...

Pregnant Dolphins Must Overcome More Than Impending Motherhood

A recent study, published in the Journal of Experimental Biology, finds that pregnant bottlenose dolphins - especially in the later stages - find their swimming speed almost halved and tail movement restricted, Victoria Gill Science reports for BBC Nature. Originally interested in how baby dolphins learned to swim, lead researcher Shawn Noren, from the Institute of Marine Science at the University of California Santa Cruz, was diving with the animals in Hawaii, and filming their behavior,...

Scientists know that the blood and tissues of some deceased beaked whales stranded near naval sonar exercises are riddled with bubbles. It is also well know that human divers can suffer from bubbles-induced decompression sickness, also known as the bends. What researchers know comparatively little about is how living marine mammals handle the compression of lung gas as they dive deep and then resurface. Now, in a study published online in the Proceedings of the Royal Society B, a team that...

Researchers Announce Discovery Of New Dolphin Species
2011-09-15 09:33:50

  A new species of dolphin native to Australia has been discovered off the coast of Port Phillip and the Gippsland Lakes by Monash University researchers, BBC News reports. The rare dolphins were formally recognized as a unique species after studies showed they are different to every other dolphin in the world. The dolphins, numbering at about 150, were originally believed to be one of two recognized bottlenose species. But by Thursday, they realized they were in fact unique and...

In a recent study to be published on April 27, 2011, in the peer-reviewed open-access journal PLoS ONE, Dr. Elliott Hazen and colleagues found that oceanographic and prey measurements can be used to identify beaked whale foraging habitat. The research team from Duke University, Woods Hole, and the Naval Undersea Warfare Center listened for foraging beaked whales and measured ocean features and distributions of prey off the east coast of Andross Island in the Bahamas. Their manuscript provides...

Project to Map Genetic Relatedness of Dolphin Populations in the South Pacific WASHINGTON, April 26, 2011 /PRNewswire-USNewswire/ -- Scott Baker, Ph.D., associate director of the Marine Mammal Institute and professor of Fisheries and Wildlife at Oregon State University, has been awarded a 2011 Pew Fellowship in Marine Conservation. His project will map patterns of isolation and interaction among populations of dolphins in the South Pacific Ocean and identify habitats important to protect...

Scientists have long been aware of a link between naval sonar exercises and unusual mass strandings of beaked whales. Evidence of such a link triggered a series of lawsuits in which environmental groups sued the U.S. Navy to limit sonar exercises to reduce risk to whales. In 2008, this conflict rose to the level of the US Supreme Court which had to balance potential threat to whales from sonar against the military risk posed by naval forces inadequately trained to use sonar to detect enemy...

Researchers reported on Wednesday that baby dolphins are washing up dead along the oil-soaked U.S. Gulf Coast at over 10 times the normal rate in the first birthing season since the BP disaster. The Institute for Marine Mammal Studies said that about 17 baby dolphin corpses have been found along the shorelines of Alabama and Mississippi in the past two weeks. "The average is one or two a month. This year we have 17, and February isn't even over yet," Moby Solangi, director of the Gulfport,...

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...

Short-beaked Common Dolphin, Delphinus delphis
2013-06-22 16:01:34

The short-beaked common dolphin (Delphinus delphis) is a species that can be found in warm temperate and tropical waters. Its range is larger than that of the long-beaked common dolphin and includes the Mediterranean and Caribbean Seas, but it is not thought to occur in the Indian Ocean. This species is classified within the Delphinus genus along with the long-beaked common dolphin. Both of these species were classified under one species, named D. delphis, until it was found that both were...

The Melon-headed Whale (Peponocephala electra; other names are many-toothed blackfish and electra dolphin) is a cetacean of the oceanic dolphin family (Delphinidae). It is closely related to the Pygmy Killer Whale and the Pilot Whales, and collectively these dolphin species are known by the common name blackfish. The Melon-headed Whale is widespread throughout the world's tropical waters, although not often seen by humans on account of its preference for deep water. Taxonomy On account...

The Australian Snubfin Dolphin (Orcaella heinsohni) is a recently recognized species of dolphin first described in 2005. It is closely related to the Irrawaddy Dolphin, and closely looks like it. Until very recently it was thought to be an Irrawaddy dolphin. However, the Australian Snubfin Dolphin is three-colored, while the Irrawaddy dolphin only has two colors on its skin. Also the skull and the fins show minor differences between the two species. The discovery of a new mammal is...
