Devil's Postpile, a spectacular example of columnar basalt. Once molten and under great pressure underground, the lava that makes up Devil's Postpile cooled evenly and slowly, contracting and fracturing into polygonal-sided columns. The age of the formation is estimated between 100 and 700 thousand years old. Sometime after the basalt columns formed, a glacier passed over the formation, cutting and polishing the tops of the columns. The columns have from three to seven sides, varying because of differences in how quickly portions of the lava cooled.

Burrowing owl, Cape Coral, Florida, subspecies Athene cunicularia floridana. This 10-inch-tall burrowing owl is standing beside its burrow. These burrows are usually created by squirrels, prairie dogs, or other rodents and even turtles, and only rarely dug by the owl itself.

The leafy seadragon (Phycodurus eques) is found on the southern and western coasts of Australia. Its extravagent appendages serve only for camoflage, since it has a nearly-invisible dorsal fin that propels it slowly through the water. The leafy sea dragon is the marine emblem of South Australia.
