Though often overlooked because of the larger and more dramatic iguanas, tortoises, and birdlife, Lava lizards (Tropidurussp) are the most ubiquitous of all reptiles in the arid lowlands. There are seven endemic species, found on all islands except the northernmost ones Genovesa, Darwin and Wolf. Their coloration varies from dull to bright red, often reflective of their immediate physical environment. Despite their small size -- rarely over eight inches -- they perch prominently on rocks in the sun, doing "push-ups" as a territorial display.
There are also several endemic species of Leaf-toed gecko (Phyllodactylus) in the islands, rarely seen due to their nocturnal behavior and preference for dark places beneath rocks or fallen trees. They may be noticed at night in Puerto Ayora, however, climbing the walls of hotel rooms or squeaking rhythmically. Their diet consists entirely of insects, which their large eyes allow them to see, their quick speed to catch.
