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

Images of shellear fish climbing up the rock face behind Luvilombo Falls

Watch These Rock-Climbing Fish Scale a 50-Foot Waterfall in the Congo Basin, the First Known Evidence of This Behavior in Africa

The tiny fish, called shellears, use microscopic hook-like growths on their fins to ascend—and they take a lot of breaks. The full climb probably takes about ten hours, according to a new study

Some 150 proboscis monkeys like this one make their home in Bako National Park, a protected area on the northwestern coast of Borneo.

The Endangered Proboscis Monkey Is Easily Identifiable By One Physical Trait: Its Supersized Schnoz

When you see this primate’s nose, you know you’re in Borneo, where efforts are underway to restore its habitat

Purple martins are long-distance migrants that nest in human-provided boxes across North America.

Purple Martins Rely on Human ‘Landlords’ to Provide Nest Boxes Each Spring. Can That Dynamic Last?

The large swallows have nested alongside human settlements for centuries. Now, the birds’ breeding success depends on caretakers who are beginning to age out of the role

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

A regent honeyeater at the Taronga Zoo in Sydney, Australia, which is one of the study sites where the critically endangered birds are being bred

This Critically Endangered Bird’s Song Was About to Disappear. Scientists Saved It by Recruiting Some Wild Vocal Tutors

Wild-born male regent honeyeaters passed their cultural knowledge to young captive-born birds

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
