We've documented sightings of glass squids to better understand the remarkable transformations they undergo from hatchlings to adults. This new observation, captured in ultra high-resolution 4K, allowed us to zoom in on a juvenile likely no bigger than a baby carrot and reveal more details than we have been able to see before.
I've wanted to be an ocean swimmer ever since I moved to Sydney. The idea of getting out past the waves and braving the elements excited me. I would tell anyone who would listen: Once I live closer to the beach, I'm going to be out there. Just you wait. I've lived walking distance to the beach for more than a year now. During this time, I've read a lot about ocean swimming: how swimmers overcame challenges or life-altering moments.
In February 2023, an article in the Mexican press announced the capture of a vessel some 195 nautical miles from the port of Lazaro Cardenas in the state of Michoacan. It had been carrying nearly 700 pounds of cocaine packaged in plastic-wrapped bricks, in addition to 1,650 liters of hydrocarbons in 33 plastic containers. Two Ecuadorian fishermen were among the five detainees, and their immigration records showed unusual activity.
'Orcas are psychos,' quipped a close friend recently. He wasn't joking, nor was he ill-informed. In fact, he is probably the world's leading historian of whales and people. He had just watched a BBC Earth clip, narrated by David Attenborough, in which three killer whales separate a male humpback calf from his mother in the waters of Western Australia. The video's closing footage, with two of the orcas escorting the naive youngster to his imminent death, resembles nothing so much as a kidnapping:
At first glance, it looked like Wooller and his colleagues might have found evidence that mammoths lived in central Alaska just 2,000 years ago. But ancient DNA revealed that two "mammoth" bones actually belonged to a North Pacific right whale and a minke whale-which raised a whole new set of questions. The team's hunt for Alaska's last mammoth had turned into an epic case of mistaken identity, starring two whale species and a mid-century fossil hunter.
It looked like the silvery blade of a knife. Peering through his goggles, diver Ted Judah had laid eyes on a deep-sea creature rarely encountered by humans. He and wife Linda were diving off McAbee Beach in Monterey County in late December when, near the surface, he spotted the undulating thing. It was some kind of ribbon fish, he wrote in a post on the Facebook group Monterey County Dive Reports. Kevin Lewand solved the mystery.
In this photo, I'm preparing drifting buoys for deployment. This was my main responsibility aboard the RV Falkor (too), during a 27-day research expedition in October 2025 exploring the Malvinas Current, an ocean current that runs alongside Argentina. The expedition included biologists, geologists and physical oceanographers such as myself; I'm a PhD candidate at the Sea and Atmosphere Research Center (CIMA) in Buenos Aires, Argentina.
Some deep-sea fish may be able to see light in a different way from most other vertebrates, according to a new study. The fish, found in the Red Sea, have what the scientists behind the new study describe as hybrid photoreceptorslight-sensing cells in the retina that combine elements of two distinct kinds of photoreceptors, cones and rods. In human retinas, cone cells enable us to see in bright environments, detecting color and fine detail,
But as he swept his flashlight through the dark waters, something unexpected emerged. Inching through the beam of light, an alien creature crawled across the surface of the sand, resembling an inch-long cluster of ghostly leaves fringed with silvery filigree and capped with a pair of antennae-like stalks. It immediately caught my eye, said Gosliner, Invertebrate Zoology Curator for the California Academy of Sciences. I've been diving there for 30 years and this one immediately struck me as different.
That seemingly paradoxical dynamic results from several factors. Foremost among them is the rebound of land beneath the Greenland Ice Sheet, a mile-thick body of glacial ice that covers 80 percent of the island and is being lost to melting at a rate of roughly 200 billion tons each year. As the ice sheet loses mass, the land beneath rises.
The lava heron also has a much thicker bill than other closely related herons - an adaptation linked to feeding among sharp volcanic rocks and hard-shelled prey. "What we learned was something that hadn't been reported before," Mendales said. The discovery underscores how much remains unknown, even in iconic places like the Galápagos, said John Dumbacher, the Academy's curator of birds and mammals and Mendales' thesis adviser.
In the pristine High Arctic sits the Kitsissut island cluster, also known as the Carey Islands, nestled between northwest Greenland and northeast Canada. The surrounding seas are perilous, and traveling there is difficult even with modern boats. But new archaeological evidence suggests ancient humans managed to sail to the islands, too. Early settlers lived on the islands between 4,500 and 2,700 years ago.
