The Dogs That Live Longest, by a Nose

All dogs go to heaven. But a bulldog might find itself headed there years before a Border terrier, according to a new study of nearly 600,000 British dogs from more than 150 breeds.

The Ancient Back Story of the Slimiest Animal in the Sea

The hagfish, a deep-sea scavenger about the size and shape of a tube sock, has the curious ability to smother itself in its own snot. The mucus is a defense mechanism, released into the water (or in one unfortunate incident, all over an Oregon highway) when the fish feels threatened. Once it hits seawater, a […]

In Colombia, a Park for Anacondas and Anteaters, Where Ranchers Are Now Rangers

Already, though, the rangers had made a difference. They had established the government’s presence in a formerly anything-goes region. Thanks to their outreach in San Martín, they had been invited in November to march in the annual parade celebrating the cuadrillas. Mr. Zorro thought that the invitation was a turning point for the park, a […]

Bird Flu Is Still Causing Havoc. Here’s The Latest.

Over the last three years, a highly contagious, often deadly form of bird flu has taken a staggering toll on animals around the globe. The virus, known as H5N1, has infected birds in more than 80 countries. It has infiltrated big commercial poultry farms and tiny backyard henhouses, affecting 72 million farmed birds in the […]

What It Takes to Save the Axolotl

Xochimilco is a large, semirural district in the south of Mexico City, home to a vast network of canals surrounding farming plots called chinampas. Starting around A.D. 900, this maze of earth and water produced food for the Xochimilcas, a Náhuatl speaking people who were among the first to populate the region and engineer its […]

Could Longevity Drugs for Dogs Extend Your Pet’s Life?

Longevity drugs are intended for healthy dogs, which changes the risk-benefit calculus. “It’s one thing if a dog is on death’s door and you’re giving them some late-breaking treatment,” said Bev Klingensmith, a Great Dane breeder in Iowa who also has a Great Dane and a golden retriever of her own. “Giving my young, healthy […]

Mucus-Covered Jellyfish Hint at Dangers of Deep-Sea Mining

A treasure trove of metal is hiding at the bottom of the ocean. Potato-size nodules of iron and manganese litter the seafloor, and metal-rich crusts cover underwater mountains and chimneys along hydrothermal vents. Deep-sea mining companies have set their sights on these minerals, aiming to use them in batteries and electronics. Environmentalists warn that the […]

Why Warblers Flock to Tonier Neighborhoods

At a meeting of urban wildlife researchers in Washington, D.C., in June, one diagram made it into so many PowerPoint presentations that its recurrence became a running joke. The subject, though, was serious: The diagram illustrated the links between structural racism, pernicious landscape features such as urban heat islands, and impacts to biodiversity, and it […]

Bats Discovered to Have Sex in a Way That’s Similar to Birds

A few years ago, Nicolas Fasel, a biologist at the University of Lausanne in Switzerland, and his colleagues developed a fascination with the penises of serotine bats, a species found in woodlands and the attics of old buildings across Europe and Asia. Serotine bats sport abnormally long penises with wide, heart-shaped heads. When erect, the […]

Do Roosters Recognize Themselves in a Mirror? Yes, They Cock-a-Doodle-Doo.

The idea of a chicken running around with its head cut off, inspired by a real-life story, may make it seem like the bird doesn’t have much going on upstairs. But Sonja Hillemacher, an animal behavior researcher at the University of Bonn in Germany, always knew that chickens were more than mindless sources of wings […]

Scientists Use CRISPR to Make Chickens More Resistant to Bird Flu

Scientists have used the gene-editing technology known as CRISPR to create chickens that have some resistance to avian influenza, according to a new study that was published in the journal Nature Communications on Tuesday. The study suggests that genetic engineering could potentially be one tool for reducing the toll of bird flu, a group of […]

In the Big City, Wildlife Researchers Are On the Prowl

Early one morning last month, Laura Dudley Plimpton found herself in Forest Park, in Queens, staring at a pair of captured raccoons. It was not the first time that Ms. Plimpton, an ecologist at Columbia University, had caught two of them in a cage trap designed for one. But typically when that happened, she would […]

To Knock an Elephant Off Balance, Bring Out a Giant Blindfold

For a 7,600-pound Asian elephant, simply putting one foot in front of the other can be a high-stakes proposition: A trip or tumble can result in grievous injury. “The bigger you are, the harder you fall,” said John Hutchinson, an expert on large animal locomotion at the Royal Veterinary College in Britain. “If an elephant […]

In Peru, a Fossil-Rich Desert Faces Unruly Development

Millions of years ago, this desert in Peru was a gathering place for fantastical sea creatures: whales that walked, dolphins with walrus faces, sharks with teeth as large as a human face, red-feathered penguins, aquatic sloths. They reproduced in the gentle waters of a shallow lagoon buffered by hills that still wrap across the landscape […]

A Mystery Species Was Discovered in Trafficked Pangolin Scales

The pangolin is an absurd animal, a mammal that’s dressed up as a reptile with a coat of scales, sharp claws and sticky saliva. Wildlife experts often say they are the most trafficked mammals in the world as poachers target pangolins for their meat and their scales, which are used in traditional medicines. There are […]

Arsenic Preserved the Animals, But Killed the Museum

Usually, you go to the zoo to look at live animals. But at the Great Plains Zoo in Sioux Falls, South Dakota, people also went to see the dead ones. The attraction, called the Delbridge Museum of Natural History, hosted one of the most impressive taxidermy collections in the country, with some 150 animals from […]

This Tiny Parasitic Wasp Can Drill Through Plastic

By the time Matvey Nikelshparg was 13, he was obsessed with parasitoid wasps, tiny insects that lay their eggs on or inside other bugs. Under a microscope in a lab he had assembled at home, he discovered that one species had a startling superpower: It could use an organ that protrudes from its abdomen to […]

You May Have This Blobby Animal to Thank for Your Nervous System

For hundreds of millions of years, pancake-shaped animals the size of a needle tip have been roving the seas with an appetite for tasty microbes and algae. They’re called placozoans, and are among the simplest of the major animal lineages. As simple as they are, a team of researchers has found compelling evidence of neuron-like […]
