A female blue crab with an acoustic telemetry tag on its shell. Scientists at the Smithsonian Environmental Research Center use telemetry tags to track the migration of blue crabs throughout the Chesapeake.

Young Blue Crabs Have Been Mysteriously Dwindling in the Chesapeake Bay for Years. This Winter, They Saw a Boost in Numbers. What’s Driving These Trends?

A recent report detailed a 50 percent drop in juvenile Chesapeake blue crabs since 2010. Then, a survey found a surprising surge in the young crustaceans this year

In February 2020, naturalist guides Lizardo Proaño and Juan Carlos Narváez photographed a harvestman eating a live frog during a night hike at Mashpi Lodge in Ecuador.

Daddy Longlegs Seem to Hunt Frogs in South America, Revealing the Gangly Arachnids as Overlooked Predators

A new study suggests that harvestmen actively attack the slippery amphibians, rather than just scavenging them. The findings hint that the spineless creatures have a more complex relationship with vertebrates than previously thought

Human development—such as roads—affects wildlife. But so does the presence of people.

The Mere Presence of Humans—Not Just Our Changes to the Land—Can Alter Wild Animals’ Behaviors, a New Study Suggests

Researchers examined GPS tracking data from thousands of animals representing 37 species and anonymized cellphone location data from 2020, a year of Covid-19 lockdowns, and the previous year

Gentoo penguins have been considered a rare beneficiary of climate change due to their population growth on the Antarctic Peninsula. Splitting the birds into four species brings to light regional threats and declines.

Gentoo Penguins Are Actually Four Different Species, Scientists Say, Revealing They’re Not Quite ‘Winners’ of Climate Change After All

A new study indicates that the adaptable birds evolved into distinct lineages as isolated populations shifted to match their environmental conditions over time. The work has implications for how conservationists assess threats to gentoos

A chick hatches around 18 days after embryo transfer to the artificial egg, according to the company.

‘De-Extinction’ Company Says It Hatched Chicks From Artificial Eggs, Paving the Way for Resurrecting Dodos and Other Bygone Birds

Colossal Biosciences announced that 26 live baby chickens have emerged from 3D-printed honeycomb structures. But the company does not plan to detail the system in a paper, and its mission has faced criticism

Sweetgrass basket weaving is one of the most enduring cultural traditions of the Gullah Geechee people, descendants of Africans enslaved on the rice, indigo and cotton plantations of the southeastern United States.

From Basket Weaving to Oyster Reef Conservation, Gullah Geechee Women Are Preserving a Living Heritage

Along America’s southeastern coast, descendants of enslaved Africans pass down traditions and knowledge of crafts, ecology and food through generations

Each by-the-wind sailor is made of a community of genetically identical organisms called "zooids" that perform different tasks.

Millions of Bright Blue Blobs Called ‘By-the-Wind Sailors’ Are Littering Beaches Along the West Coast

The strange creatures are washing up on shores across California, Oregon and Washington this spring—and making the coast smell especially fishy

Remoras might dive into manta rays' rear ends when they're scared.

This Fish Hitches Rides in Manta Rays’ ‘Buttholes,’ According to New Research

Scientists suspect that the behavior could harm the manta rays, suggesting a complex relationship between remoras and their hosts that can sometimes be parasitic

Researchers studied social learning in the birds by introducing a novel food item: colorfully dyed almonds.

Wild Cockatoos Learn Which Snacks Are Safe to Eat by Copying Their Friends, New Research Suggests

Munching on the wrong items can lead to illness, but social learning might help the birds avoid making a potentially deadly mistake. The phenomenon could help explain why certain cockatoos have fared so well in urban environments

Study author Gregory Bonito collects truffles in Australia. 

Australia Has a Surprisingly Successful Truffle Industry. This New Study Could Explain Why

Researchers examined hundreds of soil samples to uncover why the expensive fungi are thriving in the country

What if, rather than coral reef rehabilitation remaining a tedious and difficult manual process, conservationists could harness robotics, artificial intelligence and autonomous vehicles to transform it into an industrial-scale endeavor?

Could Underwater Autonomous Robots Save Coral Reefs?

Reef restoration is a slow process, with divers planting coral fragments one at a time by hand. But roboticists are now developing automated planters that could change the game

The first image of newly hatched California giant salamanders in the wild can teach biologists about the nesting habitat of the little-known species.

A Snorkeling Biologist Snapped the First-Ever Photo of Newly Hatched California Giant Salamanders in the Wild. Here’s Why That’s a Big Deal

The discovery provides another key data point about a little-known species for which every observation matters

Cool Finds

This Bone-Crunching Octopus Was Nearly the Size of a Semitruck and May Have Feasted on Giant Reptiles 100 Million Years Ago

The massive invertebrates may have been top predators, according to an analysis of their fossilized jaws. The work suggests that ancient oceans weren’t completely ruled by spine-bearing creatures, as previously thought

Volunteers have played a vital role in SERC's Functional Forests project. They've helped plant trees, put up deer fencing and mapped the tree locations with bamboo stakes, among other duties.

The Planet Needs Prosperous Forests. These Scientists Are Planting More Than 33,000 Trees to Find the Perfect Species Blends

Forests provide myriad benefits, including timber, wildlife attraction, local cooling and climate resilience. At the Smithsonian Environmental Research Center, ecologists are testing which tree combinations might create flourishing woodlands

The monkeys sometimes steal food from tourists.

Gibraltar’s Famous Monkeys Are Eating Dirt, Likely to Alleviate Stomach Aches From Munching on Tourists’ Junk Food

The British territory’s Barbary macaques are the only wild monkeys in Europe. But many are consuming human snacks high in calories, sugar, salt and dairy, and low in fiber

A camera set up by the conservation organization Panthera captured a healthy male jaguar in the Sierra del Merendón mountain range.

A Rare ‘Cloud Jaguar’ Was Spotted in Honduran Mountains for the First Time in a Decade, Representing a Win for Conservationists

The big cats are rarely seen at high elevations, so the sighting suggests that efforts to protect a wildlife corridor in the region are working

A female lynx named Ulcera carries a rabbit to a water trough and dunks it on July 16, 2024. This incident was one of eight that researchers recorded among lynxes in central Spain.

Camera Traps Reveal Iberian Lynxes Soaking Their Prey, a First-Ever Discovery Among Carnivores

Scientists speculate that the wild cats are trying to improve hydration or ease their cubs’ transition to solid food. The finding points to resilience in one of the world’s most endangered felines

Biologists with the California Department of Fish and Wildlife are working hard to eradicate nutria from the state.

Large Invasive Rodents Are Wreaking Havoc in California. New Research Suggests Someone Deliberately Introduced Them

Genetic testing revealed that nutria living in California since 2017 are most closely related to a population in central Oregon—too far for the creatures to have traveled on their own

A Symphony of Disappearing Sounds for the Great Salt Lake, Olafur Eliasson, 2026

A Glowing Sphere Towering Over Utah Sent an Urgent Artistic Message: The Great Salt Lake Is Drying Up

Olafur Eliasson’s latest installation married visuals with a soundscape to draw the public’s attention to the plight of the important ecosystem

When male greater sage grouse attempt to attract a mate, they puff up their chest, droop their wings and fan their tail feathers into a starburst shape.

One of the American West’s Most Iconic Birds Is Attempting to Mate Near a Dangerous Airport. Could Robo-Birds Help Save Them?

Conservationists are deploying dancing animatronic birds to lure male greater sage grouse away from the Jackson Hole Airport, where dozens of the creatures have been struck and killed by planes
