Whales are the earth's largest creatures, yet they are incredibly hard to study in the open ocean. For decades scientists have used boats, aircraft and even high cliffs to conduct visual surveys and gather data on whale and dolphin populations. Today, these live surveys form the basis of our knowledge of these marine mammals"”what species live where in the world, which ones tend to live together and how abundantly they are represented.Now, recent work by paleobiologist Nick Pyenson of the...
Dolphins and porpoises use echolocation for hunting and orientation. By sending out high-frequency sound, known as ultrasound, dolphins can use the echoes to determine what type of object the sound beam has hit. Researchers from Sweden and the US have now discovered that dolphins can generate two sound beam projections simultaneously."The beam projections have different frequencies and can be sent in different directions. The advantage is probably that the dolphin can locate the object more...
Hardy Jones, ocean conservationist, myeloma patient and International Myeloma Foundation (IMF) member, has written a powerful book, The Voice of The Dolphins, highlighting the devastating impact of pollutants on dolphins and our world's oceans.... Bringing in conversations with Dr Brian Durie of the IMF, he makes a compelling argument linking those same toxins to the presence of multiple myeloma in human beings. Los Angeles, California (PRWEB) May 29, 2011 Hardy Jones has written a...
Echolocation in bats and dolphins is well known. Bursts of sounds are created and the echoes that bounce back are used to locate and detect objects in the environment. What is less well known is that people can echolocate, too.Blind people have been known to learn to make clicks with their mouths and to use the returning echoes from those clicks to sense their surroundings. Some of these people are so adept at echolocation that they can use this skill to go mountain biking, play basketball,...
Bottlenose dolphins* and beluga whales**, two marine species at or near the top of their respective food webs, accumulate more chemical pollutants in their bodies when they live and feed in waters near urbanized areas, according to scientists working at the Hollings Marine Laboratory (HML), a government-university collaboration in Charleston, S.C.In papers recently published online by the journal Environmental Science & Technology, one research team looked at the levels of persistent...
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 at the Institute of Marine Mammal Studies in Mississippi claim that a federal agency's practice of returning rescued dolphins far offshore is hampering attempts to investigate dolphin deaths following the BP oil spill last year, Moby Solangi, director of the institute, tells Reuters.The National Oceanic and Atmospheric Administration (NOAA), is confirming that two dolphins found in low tide on a Louisiana beach were returned to water deep enough for them to swim away. "These...
Scientists are baffled by the continuing numbers of dead baby bottlenose dolphins washing up on the shore of the Gulf of Mexico. 406 dolphins were found either stranded or dead between February 2010 and April 2011, prompting the National Oceanic and Atmospheric Administration (NOAA) to designate the deaths as an "unusual mortality event" (UME). The agency defines such events as a stranding incident that is unexpected or involves great losses of any marine mammal population. Blair Mase, the...

Regular sightings of this species occur off the coast of Hawaii and Japan, and also in the Indian Ocean near Sri Lanka and Lesser Antilles. In the Atlantic the pygmy killer whale has been seen off the coast of South Carolina and Senegal. This species swims in...

Credit: FDrummondH/Wikipedia (CC BY-SA 3.0) The black-chinned dolphin (Lagenorhynchus australis), also known as Peale's Dolphin or Peale's Black-chinned Dolphin, can be found near Tierra del Fuego at the southern tip of South America. Within these waters, it prefers to reside in faster currents near channels or narrows, but can also be found in...
The Atlantic spotted dolphin (Stenella frontalis) can be found in the Gulf Stream of the North Atlantic Ocean, including the area between Florida and Bermuda and the Gulf of Mexico. Its eastern range may extend as far as the Azores and Canary Islands, although sightings in these areas have been uncommon. Its northern range begins at Cape Cod and extends to the southwestern portion of Spain. It is thought that the southern portion of its range extends from West Africa to Rio Grande do Sul in...
The Clymene dolphin (Stenella clymene) is a dolphin that is native to the Atlantic Ocean. It was once known as the short-snouted spinner dolphin. Although its range is not fully understood, specifically the southern portions, it does prefer tropical and temperate waters. Its range begins in New Jersey, stretching east-south-east to southern Morocco, and it is thought that the southern area of its range beings near Angola and stretches to Rio de Janeiro. It prefers habitats within deep water,...
The Ganges River Dolphin (Platanista gangetica gangetica) and Indus River Dolphin (Platanista gangetica minor) are two sub-species of freshwater or river dolphins found in India and Pakistan. From the 1970s they had commonly been regarded as separate species. The Ganges River Dolphin is primarily found in River Ganges and its tributaries in India while the Indus River Dolphin is found in the Indus river in Pakistan Taxonomy Until the 1970s the Indus and Ganges River Dolphins were...
