During major floods, thousands of tiny fish convene at Luvilombo Falls in the upper Congo River Basin to undertake a peculiar vertical migration, described for the first time today in Scientific Reports.

"Not only are acts like that illegal, but it's really harming a very important, like, a biodiversity hotspot that we have right out here," Brent Fish, an aquarist with Birch Aquarium, stated.

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.

Krill are a keystone species and the main food source for whales, penguins and seals. Aker QRILL, the world's largest harvester of krill, a tiny crustacean and keystone of Antarctica's fragile ecosystem, and its sister company, Aker BioMarine, produce feed additives for aquaculture and dietary supplements for pets and humans.

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.

Argentina's deep sea holds more biodiversity than scientists previously thought. An expedition that traveled from the north of Buenos Aires province to Tierra del Fuego, the country's southernmost point, observed the world's largest known Bathelia candida coral reef, worms, sea urchins, snails, anemones, and a specimen that captured the public's attention: a rare phantom jellyfish that can grow as large as a school bus.

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.

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.
