Dolphins Speak With Half-Nose
Russian researchers have recorded the sounds audible only inside the right part of the dolphin's nasal passage. Animals produce them during echolocation. This research can shed light on how the cetacea produce ultrasonic signals. Researchers of the Severtsov Institute of Ecology and Evolution Problems, Russian Academy of Sciences, have obtained... view more... (2004-11-01)
Swimming with dolphins can alleviate depression
Swimming with dolphins is an effective treatment for mild to moderate depression, say researchers in this week's BMJ. view more (2005-11-28)
Mercury contamination found in stranded Victorian dolphins
Monash University research into heavy metal contaminant levels in dolphins from Port Phillip Bay and the Gippsland Lakes has revealed high mercury levels may be a contributing factor to dolphin deaths. view more (2008-06-10)
Dolphins maintain round-the-clock visual vigilance
Dolphins have a clever trick for overcoming sleep deprivation. Sam Ridgway from the US Navy Marine Mammal Program explains that they are able to send half of their brains to sleep while the other half remains conscious. view more (2009-05-01)
Fighting for their attention
Mating strategies are straightforward in bottlenose dolphins, or are they? Much of the work carried on male-female relationships in that species to date show that males tend to coerce females who are left with little choice about with whom to mate. view more (2007-04-04)
Mixed dolphins and the impact of tourism
Dolphins off the coast of East Africa are exposed to a number of threats, like indirect catching, hunting, and environmental impact. In her dissertation at the Department of Zoology, Stockholm University, Sweden, Eva Stensland has studied behavioral ecology in Indo-Pacific bottlenose and humpback dolphins, off Zanzibar, Tanzania. For the last... view more... (2004-05-07)
Human language and dolphin movement patterns show similarities in brevity
Two researchers from the Polytechnic University of Catalonia (UPC) and the University of Aberdeen in the United Kingdom have shown for the first time that the law of brevity in human language, according to which the most frequently-used words tend to be the shortest, also extends to other animal species. view more (2009-07-31)
Leading scientists rank endangered dolphins, porpoises most in need of immediate action
Leading marine scientists for the first time have assessed dolphin and porpoise populations around the world which are severely threatened by entanglement in fishing gear and recommended nine urgent priorities for action in a report commissioned by the World Wildlife Fund. These nine projects highlight species threatened by bycatch that will most... view more... (2005-06-09)
Site of human-dolphin partnership becomes protected area
The government of Myanmar has established a protected area for, of all things, a partnership between fishermen and a small, gray beakless dolphin with a knack for herding fish into nets. view more (2006-06-23)
Dolphins get a lift from delta wing technology
We can only marvel at the way that dolphins, whales and porpoises scythe through water. Their finlike flippers seem perfectly adapted for maximum aquatic agility. view more (2009-06-26)
"Gray's Paradox" Solved: Researchers Discover Secret of Speedy Dolphins
There was something peculiar about dolphins that stumped prolific British zoologist Sir James Gray in 1936. view more (2008-11-25)
Dolphin 'therapy' a dangerous fad, Emory researchers warn
People suffering from chronic mental or physical disabilities should not resort to a dolphin "healing" experience, warn two researchers from Emory University. view more (2007-12-19)
Study sheds new light on dolphin coordination during predation
Spinner dolphins have long been known for their teamwork in capturing prey but a new study using high-tech acoustics has found that their synchronization is even more complex than scientists realized and likely evolved as a strategy to maximize their energy intake. view more (2008-10-21)
Whales and dolphins influence new wind turbine design
Sea creatures have evolved over millions of years to maximise efficiency of movement through water; humans have been trying to perfect streamlined designs for barely a century. view more (2008-07-08)
Study shows rise in Cornwall's dolphin, whale and porpoise deaths
Four weeks on from the shocking incident that led to the death of 26 dolphins near Falmouth, research released today (7 July 2008) sheds new light on the extent of the problems facing Cornwall's marine mammals. view more (2008-07-07)
How ancient whales lost their legs, got sleek and conquered the oceans
When ancient whales finally parted company with the last remnants of their legs about 35 million years ago, a relatively sudden genetic event may have crowned an eons-long shrinking process. view more (2006-05-23)
Scientists fear rare dolphin driven to extinction by human activities
An international research team, including biologists from NOAA Fisheries Service, has reported in an online scientific journal that it had failed to find a single Yangtze River dolphin, or baiji, during a six-week survey in China. view more (2007-09-12)
Getting a leg up on whale and dolphin evolution
When the ancestors of living cetaceans-whales, dolphins and porpoises-first dipped their toes into water, a series of evolutionary changes were sparked that ultimately nestled these swimming mammals into the larger hoofed animal group. view more (2009-09-25)
Pride of Bilbao to keep check on the ocean`s health
P&O Portsmouth`s ship Pride of Bilbao has recently taken on board more than her regular load of passengers. A box of scientific sensors has been installed in the ship`s engine room to collect valuable data about the state of the ocean each time she sails from Portsmouth through the diverse Bay of Biscay to Spain and across the Channel to Cherbourg. view more (2002-06-05)
Persistent Man-made Chemical Pollutants Found in Deep-sea Octopods and Squids
New evidence that chemical contaminants are finding their way into the deep-sea food web has been found in deep-sea squids and octopods, including the strange-looking "vampire squid". These species are food for deep-diving toothed whales and other predators. view more (2008-06-10)
