Photograph byGeorge Stone ONLY SEAGOING LIZARDS IN THE WORLD ARE THE BIG MARINE IGUANAS OF THE GALAPAGOS The Pilgrim's crew saw thousands of these fierce-looking but inoffensive reptiles (Amblyrhynchus cristatus), which feed onmarine algae inrocky places likeTagus Cove on Isabela (Albemarle) Island. Swimming with the long flattened tail, they are at home in the surf and travel fromisland toisland. Some reach alength ofabout four feet and weigh as much as 20 pounds. A pie made from another kind of iguana was offered the yachtsmen as aspecial treat (page 223). The name Galapagos comes from a Spanish word meaning "tortoise," for here dwell the famed giant species that reputedly live 300 to 500 years.
