Colorful lizards with greens, blues, indigos, and shimmery coppers dot the Spanish islands of Ibiza and Formentera. How these lizards became so kaleidoscopically diverse has long fascinated scientists. But now they are under threat as snakes gobble them up. Scientists are in a race against time to document and safeguard the diversity of lizards—see photographer Roberto García-Roa’s images of these colorful creatures and the predators who could wipe them out.

For nearly 2,000 years, the victims of the Mount Vesuvius eruption lay mute, hidden in a tomb of hardened ash. In the 1980s, National Geographic visited the scientists piecing together people’s lives and fiery deaths. These images capture Herculaneum’s haunting final moments.
