2. Galapagos Tortoise. No other animal is more synonymous with the Galapagos Islands than Geochelone elephantopus, the giant tortoise. The very name of the islands is derived from the Spanish word galapago, a term the early Spaniards used for a type of riding saddle and also applied to the “saddleback” tortoises found on the islands. Originally, 14 different subspecies of the Galapagos tortoise could be found on the islands. Today only 11 of those species remain in existence. Photo © Michael Zimring, MD, Baltimore, Maryland.

3. Red Hot Lava. A long, hot 12-mile hike in Volcanoes National Park on the Big Island of Hawai’i yielded this red-hot photo of the lava's surface flow. Lava flows are of two types,’a’a and pahoehoe. The former is rough and spiny, while the latter is ropy, billowy, or smooth like the one pictured here. They may vary in color from shiny black to dull brown. Both types have the same chemical composition; pahoehoe, however, when it erupts, is hotter and produces more fluid lava than’a’a. Photo © Robert Golomb, MD, Lafayette, California.
