These reefs are living, breathing snapshots of a watery world that you can peek into: refreshing oases where the noise of the land falls away; in its place, an intricate and utterly at-ease slice of life that you're lucky enough to witness.

Longnose spurdog sharks, locally known as kalb al-bahr, are sold on Libyan fish markets. Fishermen catch them even though they are carrying eggs, driven by economic necessity.

"There are not very many conservation issues that I'm aware of where industry and conservationists and consumers and the fishermen and the resource users all want the same thing. Every stakeholder wants less bycatch."

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.

Modern scientific societies are increasingly vulnerable due to their dependence on membership fees and journal subscriptions, which are being challenged by the rise of virtual networking and open-access publishing.

If you enter the amounts of different types of plastic that you clean up into the Wildlife Impact Calculator, it will tell you how many animal lives would have been at risk, had those items made their way into the ocean and been ingested.

Along coastlines, where tides are typically magnified, they profoundly affect navigation, commerce, coastal flooding, water properties and sediment transport. Tides impact the flooding of rivers and, thus, influence the extent of their floodplain, which has cascading effects on biogeochemical and ecological processes.

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.

To capture the biological impact of this extreme environment, I used a comprehensive suite of sensors and biomarker analyses. I wore a wireless electroencephalograph (EEG) system to monitor brain activity, sleep stages and neural signatures of stress and adaptation; the Oura Ring to continuously track sleep patterns, heart-rate variability and circadian-rhythm shifts; and the glucose monitor to follow metabolic responses in real time.

Consumers must be aware that seafood fraud, in which vendors label cheaper fish as products of higher quality and price, is common practice. According to Oceana, fish is mislabeled 25 to 70% of the time, especially when it comes to prized fish like wild salmon and Atlantic cod. Those of us who care about the environment are also concerned with traceability,

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.

The TRACX program really strengthened my research skills by allowing me to engage directly with authentic ocean core data and learn how to analyze it using real scientific methods,

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 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.

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.

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.

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.
