Galápagos: The Islands’ Environment

Our newest blog series takes a look at the Galápagos Islands, as seen in Galápagos: Life in Motion, the lavish new photographic celebration that captures the fascinating behaviors of land and sea animals that call the islands home. Each week, Princeton Nature will highlight three gorgeous photos of the Galápagos wildlife.

In The Voyage of the Beagle, Charles Darwin called the Galápagos archipelago “a little world within itself.” But it would be more accurate to see it as many worlds—a large set of unique habitats, or environmental niches, located together in a small place. This chapter presents a journey through them, beginning with the occasionally lush, but mostly inhospitable, terrain of these volcanic islands. These inland areas give way to the coastal zone, with its own complement of animals eking out an existence, which in turn transition down the water column to the shallow parts of the Pacific Ocean’s floor.

On the surface, the Galápagos Islands look very different from the tropical paradise most visitors expect. These islands are volcanic in origin and relatively young, qualities that lead to many of their otherworldly features. Land-dwelling animals need to find a niche among the costal rocks, the scrubby plants just inland, or, on some islands, in the semitropical highlands.

Giant Tortoises may be the most easily recognized land-dwelling animals in the Galápagos, but they are far from the only ones. Lava lizards are widespread; there are nine species found throughout the islands. These lizards are an example of adaptive radiation, through which closely related but distinct species have evolved on different islands. The Galápagos is also home to three species of land iguanas, who live in the scrubby inland forests.

Galápagos: Life in Motion
by Walter Perez & Michael Weisberg

The Galápagos Islands are home to an amazing variety of iconic creatures, from Giant Tortoises, Galápagos Sea Lions, Galápagos Penguins, and Ghost Crabs to Darwin’s finches, the Blue-footed Booby, and Hummingbird Moths. But how precisely do these animals manage to survive on—and in the waters around—their desert-like volcanic islands, where fresh water is always scarce, food is often hard to come by, and finding a good mate is a challenge because animal populations are so small? In this stunning large-format book, Galápagos experts Walter Perez and Michael Weisberg present an unprecedented photographic account of the remarkable survival behaviors of these beautiful and unique animals. With more than 200 detailed, close-up photographs, the book captures Galápagos animals in action as they feed, play, fight, court, mate, build nests, give birth, raise their young, and cooperate and clash with other species.

Watch male Marine Iguanas fight over territory and females; see frigatebirds steal food and nesting materials from other birds; witness the courtship dance of a pair of Blue-footed Boobies; go underwater to glimpse a Galápagos Sea Lion pup playing with its mother; and observe a baby Pacific Green Turtle enter the water for the first time. These and dozens of other unforgettable scenes are all vividly captured here—including many moments that even experienced Galápagos observers may never be lucky enough to see in person.

Complete with a brief text that provides essential context, this book will be cherished by Galápagos visitors and anyone else who wants to see incredible animals on the move.
