Scientists have discovered a fossil of a new ancient marine animal that resembles present-day dolphins. The said fossil gives a hint of how marine reptiles survived mass extinction 250 million years ago.
A plan to open a $20 million dolphin park in the Arizona desert this July has sparked an ire among environmentalists
A recent study suggests that manta rays may be self-aware as they reportedly waved at themselves and changed their behavior when in front of a mirror.
A rare Franciscana dolphin – just a baby – was the tragic victim of too much enthusiasm and even more ignorance from beach goers in Santa Terisita, Argentina.
Bycatch threatens several species of dolphins and porpoises with extinction. To mitigate the effects of accidental catches, Mexican authorities have instated an emergency two-year ban on gillnetting.
High levels of mercury have been detected in Florida's Indian River dolphins and the areas local human residents because they both consume the same seafood.
Dolphins emit sound waves to get a feel for their underwater surroundings. Researchers have reconstructed images that they say show how dolphins "see" nearby objects by recording these sounds. Those images have been popular online, but other scientists have not vetted the research.
Researchers with NOAA and University of California Santa Cruz studied dolphins recently, measuring the amount of energy they expended in making louder noises to be heard over ship noise. It was a good bit.
A rare albino Risso's calf was recently spotted swimming with its mother in Monterey Bay, Calif.
After facing several lawsuits, the US Navy has finally agreed to limit its use of sonar training devices that has harmed thousands of marine animals in the Pacific, specifically off the coast of Hawaii and Southern California.
Dolphins have long been hailed as some of the most intelligent animals in the known world, capable of complex social interaction that rivals that of even chimpanzees. Now researchers have revealed that not only do these animals enjoy cross-species friendships, but they can also enter complex alliances that last generations.
Recently, a photo of a playful dolphin riding the nose of a humpback whale has been circulating around popular social media. It's a stunning display of cross-species friendship, and certainly something to be celebrated. However, this isn't some new and strange behavior seen among a few extra-progressive dolphins. According to researchers, this kind of thing has been happening for a long time.
The bends... any deep-water diver can tell you that this unusual 'decompression sickness' is no joke. It can cause serious and immediate damage, but can also leave organs permanently marred, cutting short a diver's career if not their life. Interestingly this condition should affect all mammals, not just humans; so why don't dolphins seem to suffer from it? A new study has the answer.
Dolphins have more than one neural pathway for using sound and creating mental images, researchers say.
