In the murky waters of the Ganges and Indus rivers, a few thousand blind dolphins swim on their sides, snapping at prey with long, exaggerated beaks and using echolocation to navigate. Because of pollution and habitat destruction, the South Asian river dolphin is on its way to extinction—but a newly-discovered…
In a world’s first, researchers from the US and UK have created an impression of a submerged human as recorded by a dolphin’s echolocation.
To do it, a team led by Jack Kassewitz of SpeakDolphin.com used an imaging system known as a Cymascope. The system, developed by John Stuart Reid (who also assisted with the…
An international team of marine biologists has made the first-ever field observations of rare Omura’s whales—one of the least known species of whales in the world — while working off the coast of Madagascar.
While fishing off the coast of Cape Town in South Africa, a pair of fisherman were treated to an unbelievable sight — a massive pod of dolphins containing as many as a thousand individuals.
An international team of marine biologists has recorded an astounding round-trip journey made by a gray whale who ventured from Russia's east coast to the southern tip of Mexico's Baja California peninsula – and then all the way back. At 14,000 miles (22,500 km), it's the longest migration of a mammal ever recorded.
A federal court has ruled that the American government is failing to uphold its legal obligations to protect dolphins and whales from noise pollution produced by naval exercises in the Pacific.
Humpback whales are renowned for their ability to produce songs of remarkable beauty, complexity, and duration. But despite decades of research, scientists still aren't sure why these whales engage in such elaborate acoustic displays. Here's what we know — and have yet to learn — about the humpback whale's song.
The Sea Shepherd Conservation Society, while monitoring the activities of a poaching vessel in the South Indian Ocean, has captured unprecedented footage of an entire pod of rare "Ecotype D" orca whales.
According to one researcher, dolphins intentionally led a group of scientists to rescue a suicidal girl in the ocean near Los Angeles. Could that really be true?
One lucky research assistant caught a rare show in the Straits of Gibraltar last week, as a fin whale was spotted breaching the water three times in a row, right in front of her. While fin whales do sometimes breach, it's rarely seen and even more rarely caught on camera.
The oldest known orca whale was spotted this past weekend off the coast of British Columbia. Named "Granny," the grand matriarch is estimated to be 103 years-old. So given the extreme lifespan of these creatures, why do we still insist on locking them up in veritable goldfish bowls?
Fact: Fin whales produce an average of 974 liters of urine each day. Let's put this in perspective. That's 487 2-liter bottles of Coke. If you had that much gas (257 gallons) you could completely fill twenty 2014 Ford Focuses, and still have a bit leftover.
Perhaps you've heard that Ukraine had a small battalion of dolphin soldiers, trained to sniff out mines and patrol the border. Since the dolphins were housed at an aquarium in the Crimean city of Sevastopol, they now answer to the Russian Navy.
All whales and dolphins are descended from terrestrial mammals, ancient creatures that were very similar to the modern hippopotamus. Now, a fascinating new genetics study shows the incredible evolutionary changes these animals had to experience to become the perfectly adapted marine animals we see today.
Inside an unassuming L.A. warehouse, a bearded man in rubber gloves and a bloodstained t-shirt is pulling bodies apart. The stench is powerful, but conveniently masked by the fleshy funk of a nearby meatpacking plant. He removes a glistening lump of muscle and plops it on a table. "There's the heart" he says cooly.…
In case you still doubted that dolphins have an awareness rivaling our own, new research shows that these cetaceans can remember the whistles of their old tank-mates after being separated for more than 20 years! No species other than humans has demonstrated such a long-term social memory.
These divers had an incredibly close encounter with two humpback whales recently, while exploring the waters of Central California's Souza Rock.
Scientists have known for years that mid-frequency sonar can harm deep-diving toothed whales, such as by driving them from feeding grounds. Research now shows that the naval noise even elicits stark behavioral changes in blue whales, which communicate at frequencies far below sonar frequencies, suggesting that the…
The crew of marine-minded misfits running the show at Deep Sea News recently posted a rebuttal to Treehugger's well-meaning, but ultimately ingenuous, list of 10 Reasons Why Dolphins Are Undeniably Awesome. DSN's list? 10 reasons that dolphins are raging assholes.
If this video of interspecies collaboration doesn't warm your heart, you probably don't have a heart. When a dolphin gets caught on a fishing hook, it seeks out this group of human divers for help, resulting in a remarkable display of trust, intelligence and cooperation - from both species.
