Scientists studied the fossils of prehistoric relatives of katydids.

Scientists Recreated the Long-Lost Chirps of Jurassic Insects. Listen to the Simulated Soundscape of 165 Million Years Ago

With artificial intelligence and careful modeling of fossilized wings, researchers reproduced how some extinct, katydid-like insects might have made noise

The annual contest highlights not only birds but also their behaviors, habitats and threats.

These 20 Breathtaking Bird Images From the Audubon Photography Awards Capture the Wonder of the Winged World

The winners of the 17th annual contest reveal the beauty of birds, the splendor of their migratory journeys and the risks they face

Researchers have spent the past two years studying the interactions between common octopuses and blue crabs and perfecting breeding techniques.

Blue Crabs Have Taken Over the Adriatic Sea. To Fight Them Off, Italian Researchers Just Released Thousands of Baby Octopuses

Although prized in the United States, the crustaceans have been decimating ecosystems and the fishing industry in Italy. Experts hope that an army of natural predators—common octopuses—can help contain the invasive species’ spread

In loud conditions, a tokay gecko adjusts its call, which is typically used to find a mate or defend territory.

Reptiles Make a Surprising Amount of Noise. Here’s What Those Sounds Might Mean, From Pops to Hoots to Bellows

Scientists are realizing that turtles, lizards and crocodilians communicate vocally more than they once thought

Alfie and Bailey, the first dogs whose genes were edited so they lack the allergy-inducing protein Can f 1.

Allergic to Dogs? These Gene-Edited Beagles Could Pave the Way to Your Dream Canine Companion That Won’t Trigger Sniffles

Geneticists altered Alfie and Bailey’s DNA so that they don’t produce a major allergen. However, canines like them are not currently commercially available, and some experts express ethical concerns about altering the animals’ genes

An artist's interpretation of what Chosha praecursor might have looked like while splitting its time between water and land 324 million years ago in what is now Texas.

This Ancient Insect Had 24 Legs—and Could Help Explain How the Ancestors of Modern-Day Bugs Took Over the Land

A previously undescribed critter that lived 324 million years ago appears to have been a transitional species that lived between land and sea. It could help researchers fill an 80-million-year gap in the fossil record of how crustaceans evolved into insects

A male Cope's gray treefrog is smaller than a female and attaches to her back as she looks for a spot to lay eggs.

Female Treefrogs Experience ‘Choice Overload’ Amid Too Many Mating Calls From Males

Faced with a chorus of potential mates, female Cope’s gray treefrogs may be overwhelmed by the number of options and struggle to make a careful decision, a study suggests

A new museum focused on the world of whales will open next year in Norway.

A New Museum in Norway Is Bringing Visitors Into the World of Whales—From Life-Size Orcas to Immersive Underwater Exhibits

Opening in 2027, The Whale will explore the science, behavior, evolution and cultural history of whales through art, storytelling, sound and architecture

Meet the Newly Discovered Fuzzy Fish Species Named After Mr. Snuffleupagus From ‘Sesame Street’

The ghost pipefish’s scruffy appearance probably helps it look like floating algae, allowing it to blend in with its environment. Researchers had been on the hunt for this strange creature for years after first spotting one more than two decades ago

Researchers observed bearded capuchins in Brazil eating birds (shown here), lizards, rodents, opossums, snakes and other small vertebrates.

When Fruit Is Scarce, These Monkeys Hunt Animals. The Behavior May Offer Clues About the Origins of Humans’ Meat-Eating Habits

The bearded capuchins of northeastern Brazil typically eat plant-based foods, but they turn to small vertebrates when those sources are limited. Our ancestors may have done the same, eventually allowing predatory behaviors to be more frequently passed on in our lineage

The studied species, brown-lipped snails, are native to Europe.

Snails Can Make Their Slime Sticky, Slippery, Foamy or Hard Depending on Their Needs. Here’s How They Tweak Their Multipurpose Mucus

The critters can alter the proportions of calcium and collagen in the versatile substance, which changes the protein structure. The different textures can help snails glide, climb or protect themselves

Paleontologists Discover a New Species of Ice Age Toad at the La Brea Tar Pits, Offering Clues About the Area’s Ancient Climate

The fossilized remains, recovered in 1929, were part of La Brea’s relatively understudied amphibian collection. Since toads are cold-blooded and sensitive to environmental changes, the discovery can help researchers piece together past climate conditions

This might be the view a seal gets as it comes up from underwater to breathe: a polar bear, looking down for its prey.

See 16 Stunning Animal Images From the Wildlife Photographer of the Year Awards

Now in its 62nd year, the famed competition has released a sneak peek of the entries from this contest ahead of announcing the winners in October

Marmots can spend up to eight months in hibernation, so packing on the pounds during the short alpine summer is essential to their survival.

Cast Your Vote for the Chunkiest Alpine Rodent During Colorado’s First-Ever Fat Marmot Week

The inaugural competition puts eight yellow-bellied marmots head-to-head while shining a light on the science behind their seasonal weight gain and survival at high elevations

A long-clawed shrew seen in northern Japan

These Tiny Shrews Grow Bigger Snouts and Shrink Their Brains to Survive Harsh Winters, Study Suggests

Scientists have long known that some small mammals reduce their brain size during cold months and regrow them in the spring. Long-clawed shrews from Hokkaido, Japan, seem to follow that pattern—while their noses surprisingly do the opposite

In Pompano Beach, a museum dedicated entirely to jellyfish has recently opened its doors. 

‘Only One of Its Kind’ Jellyfish Museum Astounds Visitors With Awe-Inspiring Displays of Sea Nettles Safely Behind Glass

The museum opened in the spring and was founded by two aquarium experts who fled the Russia-Ukraine war

The team combined two operating tables to hold the snake's lengthy 110-pound body.

This 15-Foot Python Is the First Known Snake to Receive Electrochemotherapy for Cancer. Now, She’s Officially Free of the Disease

The pioneering treatment makes it easier for traditional chemotherapy drugs to penetrate cancer cells. After the procedure, the reptile, named Jodie Foster, made a speedy recovery

The researchers trained pet dogs to sit still during an MRI scan.

Scientists Gave Dogs MRIs and Learned That They’re Surprisingly Good at Distinguishing Between Human Emotions, Even Some Negative Ones

A recent study found that man’s best friend processes positive and negative human emotions differently and can distinguish between fearful faces and those showing sadness or anger

The right side of the bird's body is male while the left side is female.

An ‘Extremely Rare’ Half-Male, Half-Female Bird Temporarily Took Up Residence Outside of Chicago

Narwhals Sport Iconic Straight, Spiraled Tusks. Scientists Just Uncovered Some of the Eye-Catching Feature’s Structural Secrets

The Arctic whales are the only known animals with straight tusks, and ones that consistently twist to the left. New research reveals that the inner layer twists to the right and that the opposing spirals provide strength and help the tusks grow straight
