Tiny Crustaceans Move 110 Pounds of Sand Per Meter Overnight, Reshaping California Beaches

Researchers at the University of California, Santa Barbara, have discovered that sand hoppers, a small crustacean, are a major force in reshaping California's coastline. These inch-long animals move up to 50 kilograms of sand per meter of shoreline in a single night. Their activity, known as bioturbation, rivals the sediment movement of major rivers and significantly impacts dune formation and beach ecology.

A 30-year-old ribbon worm in a Virginia lab tank rewrites the record for nemertean longevity

A 30-year-old ribbon worm in a Virginia lab tank rewrites the record for nemertean longevity

A three-foot ribbon worm named Baseodiscus the Eldest, kept in a lab tank at William & Mary since 2005, is estimated to be roughly 30 years old, making him the oldest known nemertean. Genetic analysis in 2024 confirmed his species as Baseodiscus punnetti, while his age was determined through captivity records rather than biological markers. This accidental discovery challenges previous assumptions that ribbon worms live only a few years, suggesting they may be long-lived benthic predators. The finding highlights the importance of long-term observation in biology and opens new avenues for studying aging in marine invertebrates.

Hayden Panettiere's Final PETA Campaign Highlights a Lifetime of Animal Advocacy

Hayden Panettiere's last PETA campaign was filmed in Los Angeles weeks before her death at 36, featuring her in a bathtub protest against marine parks as a capstone to a lifelong animal-welfare career that included protests against dolphin hunts in Taiji and activism with the Whaleman Foundation; authorities say autopsy found no trauma and the cause of death remains under investigation, with the DEA assisting.

Europe's seas hit record heat as climate change endangers marine life

Human-caused climate change is driving record sea temperatures around Europe, with the Mediterranean averaging 27C in July and a Mallorca buoy reaching 33C in August. The World Weather Attribution analysis estimates warming of about 2C in the Mediterranean and 1.4C in western European seas would be unlikely without human influence, fueling marine heatwaves that threaten ecosystems, fisheries, and coastal communities as species shift north or die off.

Nine Weird Crabs: Toxic Killers, Giant Shellade Barbarians, and Other Ocean Oddities

Nine Weird Crabs: Toxic Killers, Giant Shellade Barbarians, and Other Ocean Oddities

Nine ocean crustaceans nicknamed crabs—many aren’t true crabs—showcase toxic defenses, colossal sizes, and unusual adaptations: from the toxic xanthid crabs and the car-sized Japanese spider crab to porcelain and hermit crabs, boxer crabs that wield anemone “gloves,” spiny spider crabs’ debris camouflage, devil crabs’ neurotoxins, spanner crabs’ tool-like claws, and zebra crabs that parasitize venomous urchins; the piece also explains what defines a true crab and how evolution can reshape crustaceans.

El Niño Threat Looms: California Faces Wet Winters, Flood Risks, and Shifts in Sea Life

El Niño Threat Looms: California Faces Wet Winters, Flood Risks, and Shifts in Sea Life

El Niño has arrived and could be among the strongest on record, likely bringing a wetter winter to California, higher coastal flooding risk, and warmer coastal waters that may draw more sharks and other marine life nearshore, while also stressing ecosystems and potentially triggering harmful algal blooms and fishing impacts.

El Niño Arrives: SoCal Prepares for a Potentially Wet and Ocean-Changing Winter

El Niño has arrived with a 63% chance of a very strong event later this year, increasing the odds of a wetter-than-normal California winter. Past very strong El Niños brought heavy rain and damage, though rainfall isn’t guaranteed and coastal hazards like large waves and rip currents can accompany wetter years. Beyond weather, warmer Pacific waters and marine heat waves linked to El Niño may affect ocean life—with more jellyfish and sharks, kelp loss, and stress to other species—likely keeping ocean conditions unsettled into next winter.

The Venomous Beauty of Cone Snails: Harpoons, Toxins, and the Danger of Collecting Shells

The Venomous Beauty of Cone Snails: Harpoons, Toxins, and the Danger of Collecting Shells

Cone snails are a diverse group of venomous sea snails that hunt with a harpoon-like tooth that injects neurotoxins, quickly paralyzing prey and sometimes causing death in humans; their striking shells attract collectors, but even empty shells can injure due to residual venom, so people are advised to avoid handling them and to photograph instead, with some areas even restricting shell removal.
