The little-studied reptiles may use their strange horns to communicate with mates or rivals, new research suggests.
When it comes to choosing a mate, male lizards tend to go for more “feminine” females without blue necks, a new study says.
It’s no lie—scientists have spotted a lizard whose males have noses like Pinocchio in the Amazon rain forest.
Four new species of legless lizard have emerged from a railroad track, vacant city lots, oilfields, and even an airport runway, a new study says.
Join us this week, as we explore the labyrinth of underwater caves deep under Mexico’s Yucatan Peninsula for clues of its Mayan past, cycle solo through Central Asian mountain passes to climb remote peaks, and debunk American historical myths from the Wild West to the Surfin’ Safari.
At the research site: More pink grasshoppers, invertebrates galore, a few lizards and the first wild bear sighting!
The mysterious arrival of a zoo anteater has some talking virgin birth, or parthenogenesis. See what other animals have babies without fathers.
For the last few days Harith Farooq, a Mozambican scientist from the University of Lúrio in Pemba, and his colleague, MO Roedel from Berlin, two herpetologists participating in a biodiversity survey of the Cheringoma Plateau in Gorongosa National Park, have been trying to catch some of the many lizards found in the Nhagutua Gorge, the site of our first camp. Alas, the sneaky reptiles proved to be extremely difficult to catch by hand, which prompted Harith to come up with an alternative solution.
Get a first-person view of life in the field from amphibian and reptile biologist, Edgar Lehr exploring remote areas of Peru for new species of frogs and lizards.
A colorful mystery critter from this year’s BioBlitz gets identified and shown off in all its cold-blooded glory.
At the end of their Spanish lizard-photographing expedition Neil Losin and Nate Dappen stumble on lizards of such a variety of color that it blows the biologists’ minds.
In the Spanish Mediterranean islands of Ibiza and Formentera to create a book about the endemic Ibiza Wall Lizard, Neil Losin and Nate Dappan get the rare opportunity to summit a legendary island two miles off shore.
National Geographic Young Explorer Neil Losin continues his research and adventures in and around Formentera, Spain, to reveal the secrets of life as a local lizard.
As a biologist, I love surprises. And after the first week of our month-long photographic expedition to the Mediterranean islands of Ibiza and Formentera, it seems like there are biological surprises around every corner. Dr. Nate Dappen, an evolutionary biologist from the University of Miami, has spent the past three summers on Ibiza and Formentera…
The spectacular Pityusic Archipelago lies 50 miles east of Valencia in the Spanish Mediterranean. Most people know Ibiza, the largest island in the archipelago, for its spectacular beaches, crystal-clear waters, and world-famous nightlife. But as anyone who has visited Ibiza will tell you, the island’s official symbol is one you’d never expect – a lizard!…
USGS herpetologist Cecil Schwalbe is a popular scientist at the Saguaro National Park BioBlitz. He demonstrates some of the charismatic reptiles found in the park, including a venomous lizard, a snake-eating snake, and a tortoise that survives the desert drought by holding in its pee and poop.
While famous figures continue to make discoveries and lead thrilling expeditions, a new group of National Geographic Young Explorers are laying the foundations for the future. If you’re in D.C., join us at Headquarters this Friday to meet Shannon Switzer, Neil Losin, and Emily Ainsworth.
The genome of Anolis carolinensis has just been published in the journal Nature, and most attention is focusing on how this genome, the first reptile to be sequenced (not including birds), differs from other vertebrate genomes, and what these differences may tell us about genome evolution.
NG Young Explorer Neil Losin reveals the method behind the madness of his latest experiment catching tiny lizards called anoles in the wilds of urban Florida.
This week on National Geographic Weekend radio, host Boyd Matson speaks with guests about the oceans, gorillas, Cleopatra, girlfriend getaways, giant squid, dodo DNA, Indian tigers, lizard extinctions, and the life and times of a CIA agent turned Buddhist priest. Hour 1 Six-time National Geographic Expeditions Council grantee Jon Bowermaster is the editor of a…
This week on National Geographic Weekend radio, host Boyd Matson speaks with guests about the ocean’s ultimate abyss, Miami tweets, Chinese tea, Tibetan horses, giant lizards, sustainable seafood, solitary lockup, ecotravel, charging gorillas, and Vietnam. Hour 1 There is only one living person who has ever been to the deepest part of the ocean, the…
Female brown anole lizards have figured out how to pass on the genes of large males they mate to their sons, and the genes of small males to their daughters, Dartmouth College biologists have discovered. Female brown anoles (center) produce more sons via large sires (left) and more daughters via small sires (right). Image © Science/AAAS…
Competition among male side-blotched lizards takes the form of a rock-paper-scissors game in which each mating strategy beats and is beaten by one other strategy, research has shown. Barry Sinervo, a professor of ecology and evolutionary biology at the University of California in Santa Cruz (UCSC), has monitored the mating game in a population of…
