Galápagos: Finding Food

Adapted from pages 54-64 of Galápagos:

Galápagos Sea Lion.

Galápagos animals organize much of their lives around the search for food. Because there is so little food on these mostly barren islands, these animals display a remarkable set of adaptations for finding it. This chapter explores the behaviors of the hunters and the hunted, vegetarians, sand grazers, and food stealers. We will encounter underwater foragers who can excrete excess salt from seawater and omnivorous birds who drink the blood of baby sea turtles. But like so much in the Galápagos, our story of Galápagos animals finding food begins in the ocean.

Flightless Cormorant catching a Barberfish.

Mature Galápagos Sea Lions survive by catching and eating fish. They forage over enormous distances, swimming six or more miles per day to find food. Other animals know sea lions are good at fishing, and some birds employ the strategy of trying to steal a meal from them.

A Ghost Crab.

Many Galápagos animals live right at the water’s edge, either catching their prey along the coast or venturing farther out to sea to find a meal. But not all animals who depend on food from the sea eat fish. For example, Marine Iguanas are vegetarians, foraging exclusively on algae underwater and along the coastline. They sneeze to excrete the excess salt they ingest by swallowing seawater. And sea predators themselves sometimes become food; Galápagos Hawks sometimes eat Galápagos Sea Lion and Galápagos Fur Seal carcasses, placentas, and pups.

 

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 senes 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.
