Why is the Amazon rainforest important?

Watch this five-minute video from National Geographic to learn about the importance of the Amazon rainforest and the risk of what's to come if humans continue to deforest it. The Amazon rainforest is about the same size as the continental United...

The largest river on Earth is actually in the sky

High above the canopy of the Amazon rainforest drifts an airborne river fed by the towering trees below. The trees pull water from their roots into their trunks, pushing any excess water out of their leaves and into the atmosphere as vapor. Watch this six-minute video to learn how.

River dolphins manhandle an unlucky anaconda

The natural world around us is endlessly inspiring, and fascinating, and often very odd too: like when researchers snapped a photo of Bolivian river dolphins swimming around with a Beni anaconda snake in their mouths, for example.

Mammals thrived under the feet of dinosaurs

An explosion of fossil finds reveals that ancient mammals evolved a wide variety of adaptations allowing them to exploit the skies, rivers and underground lairs.

Zoo animals have developed allergies, too

Although scientists do not know if allergies manifest among wild animals—and if animals can survive with them—in a zoo setting, veterinarians have observed zoo animals with common allergy symptoms, including itchiness, crusty skin, and runny eyes. Veterinarians have identified Asian elephants with pollen allergies and at least one jaguar with an allergy to fleas.

About 1,500 species of tardigrades have been identified by their unique physiology

Freshwater-bound eutardigrades live on mosses and lichens and are distinguished by variations in the shape and number of claws at the end of their legs. Marine heterotardigrades, which live on algae and deep-sea sediments, have been observed to possess feathers, inflatable appendages, and flagpole-like tails.

South American lungfish has the largest animal genome, with 91 billion base pairs

This genome is 30 times larger than a human's due to significant amounts of "junk DNA" and jumping genes, or transposons. Transposons can jump or copy over to other parts of a genome and may aid adaptation.

Some animals have little or no bacterial populations in their gut

Gut microbiomes are essential to human health, but many animals have a much smaller, transient, or even nonexistent microbiome. The discoveries have advanced our understanding of the evolution of the human microbiome.

Spanning the waters of Indonesia, Malaysia, Papua New Guinea, the Philippines, the Solomon Islands, and Timor-Leste, the region contains more than 600 coral species and over 2,200 of the world's coral reef fish species. It sustains 120 million people with food and other resources, as well as a $12B yearly tourism industry.

'Sloth fever' is an emerging health threat, especially to pregnant women

This disease, caused by the Oropouche virus, is found in animals including sloths, primates, and birds. It primarily spreads through the bite of midges—insects commonly called "no-see-ums." It's endemic to the Amazon region, but US travelers are increasingly contracting it internationally.

Less than 0.1% of the approximately 20,000 known bee species make honey

The majority of honeybee species originate in South and Southeast Asia, with the largest—Apis laboriosa—found almost exclusively in the Himalayas. The smallest is the black dwarf honeybee, Apis andreniformis, which inhabits tropical and subtropical regions of the continent.

Nine different studies exploring animals' relationship to music

Researchers have conducted multiple studies attempting to answer a certain question: do animals like human music? Across species, they observed different results and no clear pattern. Primates appear to prefer silence, and cockatoos appear to dance to funky beats.

Three Ebola species are responsible for most large outbreaks of the disease, yet the only approved Ebola vaccine is known to work against just one of them.

Two marsupials thought to be extinct discovered in New Guinea

The pygmy long-fingered possum and the newly described ring-tailed glider were discovered in 2026 after scientists believed the species had been extinct for 6,000 years. The pygmy long-fingered possum is partially defined by its unusual trait of one finger on each hand that is twice as long as the others.

Tigers emerged much earlier as a species than lions

Both lions and tigers are iconic big cats known for their size and power, but they remain distinct species. Beyond just looking different, they can exhibit very different behaviors. For example, tigers are significantly less social than lions, who live in social matriarchal groups. Tigers and lions are unlikely to ever interact in the wild, but humans have artificially bred them in captivity, creating a "liger."

Venezuela's Lake Maracaibo is considered the lightning capital of the world

Spread across 140 to 160 nights, and as many as 10 hours per night, the region where the Catatumbo River flows into the semi-enclosed bay experiences approximately 1.6 million lightning strikes annually. The frequency of strikes may originate from warm Caribbean air interacting with cooler air from the Andes.

Brazil is leading a cheese revolution and challenging European dominance in the industry

Brazil has plenty of traditional dishes that rely on cheese, but it’s only in the last decade that the country has emerged as a powerhouse in artisanal cheesemaking. While the cheeses may be inspired by European traditions, options like cocoa-dusted goat cheese or an Amazonian buffalo cheese are pure South American.
