A female Macleay's specter stick insect pauses on a branch at the Cincinnati Zoo. Indigenous to Australia, these large, well-defended arthropods are covered in tiny spikes and can reach 6 inches (15 centimeters) in length.

Grand Canyon National Park, Arizona, 2005
Photograph by Michael Nichols
A pool of rainwater in a Grand Canyon boulder reflects canyon and sky. A writhing giant with scores of limbs (some still unnamed), the Grand Canyon slices 277 miles (446 kilometers) through northern Arizona, extending 18 miles (29 kilometers) at its widest point and 6,000 feet (1,800 meters) at its deepest—one of Earth's largest canyon systems. Cut by the Colorado River in the past six million years, it exposes rock strata that detail nearly two billion years of North America's geologic history.

Photograph by Tim Laman

Prehistoric Human Skull, Qafzeh, Israel, 2001
Photograph by Robert Clark
This 100,000-year-old skull was found in a cave in Qafzeh, Israel, along with other fossils, including a horse tooth and burned flints. Cutting-edge techniques were used to date the fossils—revealing that modern humans left Africa much earlier than had been thought, even coexisting with Neanderthals, once believed to be our ancestors.

Jumbo Squid, Atlantic Ocean, 2004
Photograph by Brian J. Skerry
With an angry eye and a cloud of ink, a jumbo squid (Dosidicus gigas) flees from a diver. If camouflage fails, squid use ink as a backup defense. Mexican fishermen call the aggressive creatures "diablos rojos"—red devils. They often spew water from their funnels when hauled aboard.

Blue Hole and Diver, Ichetucknee Springs, Florida, 1999
Photograph by Wes C. Skiles
A column of sunlight illuminates a diver in the diamond-clear waters of Blue Hole in North Florida’s Ichetucknee Springs State Park. Conservationists worry that Ichetucknee, one of the crown jewels of Florida's parks system, could become polluted by runoff far from the park's center.

A collared kingfisher preens in the Sundarbans mangrove forest of Bangladesh. A vast breakwater on the Bay of Bengal, the Sundarbans covers nearly 4,000 square miles (10,000 square kilometers) of Bangladesh and India, making it the largest mangrove wetland on Earth. Worldwide, these coastal forests thwart wave-driven erosion and capture riverborne sediments as they meet the sea, building new land.

Photograph by Steve Raymer
A woman smoking opium on Chinese New Year fills her small, sunlit home in Thailand's Doi Sam Mun village with a bluish haze. Thailand was once a significant producer of opium and heroin, but government eradications efforts begun in the 1980s have significantly curtailed poppy cultivation.
