Modern fish traps require pilings that are driven into the riverbed and netting that reaches across part of a river.

Fish Traps Have Been Banned on the Columbia River for Nearly a Century. Could Bringing Them Back Help Save Salmon?

A new experiment is testing the commercial success of fish traps in Washington and Oregon. Even as some conservationists embrace the technique, its return has reopened old wounds among local fishers

Scientists Capture the First Known Footage of Sperm Whales Headbutting, a Long-Debated Behavior That Inspired ‘Moby-Dick’

Engaging in “rough play” might help young males practice for future headbutting contests in which they compete for mates

Researchers recently discovered that platypuses are the only known mammals with hollow melanosomes, a pigment-filled structure that gives hair, fur, skin, feathers and eyes their color. 

Platypus Hair Shares a Puzzling Feature With Bird Feathers, Adding to the Egg-Laying Mammal’s List of Unusual Characteristics

The species’ melanosomes—tiny, pigment-filled structures inside hair cells—are hollow, a trait never before seen in mammals

These Stunningly Detailed 3D Images of Ants Showcase the Remarkable Diversity Across Their Many Species

Scientists used a game-changing technique to scan about 2,200 preserved specimens in just one week to create the Antscan database

Participants listened to pairs of mating calls made by numerous creatures, including male green treefrogs.

Humans and Animals Often Like the Same Mating Calls, Supporting a 150-Year-Old Observation by Charles Darwin

New research by Smithsonian scientists suggests that preferences for certain sounds might be evolutionarily conserved

European hedgehog numbers are shrinking.

European Hedgehogs’ Hearing Might Be Attuned to Ultrasonic Sounds. The Discovery Could Help Scientists Save the Declining Species

Sound-based deterrents could help keep the animals away from fast-moving cars and dangerous landscaping equipment

Researchers spent six years observing interactions between bull sharks at Fiji's Shark Reef Marine Reserve.

Bull Sharks Are Large, Aggressive Predators—but They Also Know How to Make ‘Friends,’ New Research Suggests

The animals probably socialize to learn new skills and to find food and mates

Like Astrophage, the solar-radiation-eating microbes in Andy Weir’s novel Project Hail Mary, some sea slugs can derive energy from sunlight.

These Sea Slugs Can ‘Eat’ Sunlight—but They’re No Astrophage. Here’s How the ‘Project Hail Mary’ Antagonist Has a Real-Life Analogue in Earth’s Oceans

By snatching chloroplasts from algae, animals called sacoglossans produce their own energy through photosynthesis

Yaks on the Tibetan Plateau have adapted to deal with high-altitude conditions.

This Genetic Mutation Helps Yaks Survive at High Elevations. It Could Lead to Treatments for Nerve Damage in Humans

Animals that dwell at high altitudes have adapted to cope with low oxygen levels, a condition that damages a vital part of nerve cells

Scientists tracked the breeding behaviors of king penguins on Possession Island, part of the French-controlled Crozet archipelago.

King Penguins Seem to Be Benefiting From a Warming World. While That’s Good News for Now, It Could Spell Trouble for the Future

The birds are breeding earlier, and more of their chicks are surviving. But researchers fear this success may not last

The shin bone was found in New Mexico.

This 74-Million-Year-Old Dinosaur Bone May Have Belonged to a Surprisingly Large Ancestor of Tyrannosaurus Rex

The massive reptile may have weighed more than 4.5 tons and been 35 feet long—much bigger than its related peers at the time

Even common backyard birds like house finches are disappearing.

North American Bird Losses Are Accelerating. New Research Suggests Fertilizers and Pesticides May Be to Blame

Scientists found the severest changes in decline rates in places that include hallmarks of high-intensity agriculture

Some researchers think that two varieties of orcas are so different that they should be considered separate species. 

Do These Severed Orca Fins Covered in Tooth Marks Mean Killer Whales Are Cannibals? It’s Complicated, Scientists Say

Researchers suggest that predation by a subspecies called Bigg’s orcas might explain why members of another one, called resident orcas, stay in such large family groups

Common eastern bumblebee queens use underwater breathing and anaerobic metabolism to survive when submerged.

Bumblebee Queens Breathe Underwater to Survive Drowning, Revealing How They Can Live Submerged for a Week

After scientists accidentally discovered that the common eastern bumblebee can withstand flood conditions, they wanted to investigate what makes that super-ability possible

This Ancient Reptile Started Life on All Fours. As It Grew, It Stood Upright and Started Walking on Two Legs Instead

Scientists have identified a strange early crocodile relative that may have looked somewhat like a flightless bird

When photographer Elliot McGucken heard about a possible superbloom in Death Valley this spring, he drove around 1,000 miles from Montana to California.

Vibrant Wildflowers Are Blanketing Death Valley National Park, Resulting in the Most Breathtaking Bloom in a Decade

Parts of the park are awash in wildflowers, from the cheery yellow blooms of desert gold to the bright purple clusters of sand verbena, along with many other species

Between 500 and 1,000 koalas were estimated to live in Victoria, Australia, in the 1920s.

These Koalas Bounced Back From the Brink of Local Extinction Extremely Fast. Surprisingly, So Did Their Genetic Resilience

Conservationists saved the fuzzy creatures in Victoria, Australia. Now, the animals are showing remarkable signs of genetic recovery

The pygmy long-fingered possum uses its specialized ears and long digits to hunt for grubs in rotting wood.

Scientists Thought These Marsupials Went Extinct 6,000 Years Ago. They Just Found the Animals Alive
