Spreading through the Americas, one lizard group, the anoles, evolved like Darwin's finches, adapting to different islands and different habitats on the mainland. Today there are more than 400 ...

The vast diversity of anole lizards found throughout the Americas helps scientists understand what factors drive the evolution of life. (goatling, CC BY 2.0) Contemplating the diversity of life on ...

Each lizard is unique. Some have longer legs, others stronger jaws, and all behave slightly differently. The differences could determine who survives.

Few lizards leave or come to the island, and they all face the same predators and other pressures. They also inhabited different niches in the habitat — brown anoles are ground hunters, bark ...

The anoles were seen periodically inflating the bubbles and then drawing them back in through their noses—so to test if they use these bubbles to breathe, scientists observed the reptiles ...

In a Costa Rican rainforest, a small, semiaquatic lizard called a diving anole leaps into a stream. Minutes pass, but the anole doesn’t surface for air, as these lizards typically do.

When it comes to studying lungs, humans take up all the air, but it turns out scientists have a lot to learn from lizards. A new study from Princeton University shows how the brown anole lizard solves ...

The diving anole lives in Costa Rica’s rainforest, where it’s able to form small air bubbles atop its head as a source of oxygen when submerged. This ability allows the lizard to stay ...

Lizard-eating corn snakes are also out hunting, trying to find the anoles before we do. As we wrap up another 16-hour day at about 11:30 p.m., the team shares stories of the night.
