Marine biologists working off the northwest coast of Australia have observed a rare mating display in which male dolphins were seen gathering and offering large marine sponges to females. Scientists have never seen this behavior in dolphins before, highlighting a previously unknown level of social complexity.
An investigation into the oral health of captive orca whales is raising serious concerns about the health and welfare of these majestic creatures. Out of boredom and frustration, many of the whales turn to chewing on concrete and steel tank surfaces, causing wear and tear that leads to further problems.
Last year brought what seemed like a disturbing omen to communities surrounding Europe’s North Sea: a whole lot of beached sperm whales. As Gizmodo reported at the time, the whales entered the sea’s shallow waters, where their internal sonar-like systems stopped working, causing them to become stranded and die. But…
As apex predators, orcas can prey on whichever marine animal they choose—large or small. During a recent expedition off the coast of the Kamchatka Peninsula, scientists captured rare footage of orcas attacking a 40-foot-long minke whale.
By now, you probably know that humans are really screwing up the ocean. Climate change aside, we often dump oil into it, ruining the lives of whatever animals live nearby. Just imagine if someone drilled for oil right in the center of your house and then accidentally got the toxic black sludge all over your bedroom,…
Sightings of True’s beaked whales are so rare that even the most devoted whale expert can go an entire career without ever seeing one in the wild. Researchers working near the Azores are now the first to ever capture underwater footage of these aquatic creatures in their natural habitat.
Unbelievable footage from Australia shows a whale calf as it desperately tries to free its mother from a sandbank.
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.
