Reptiles are now kept in one out of every seven pet homes, so it's no surprise that millions have gone gaga for geckos. This fun, easy-to-follow guide provides the scoop on caring for these colorful, gentle creatures, with savvy tips on everything from diet and exercise to housing and veterinary care. The book covers how to properly handle a gecko, what to do if a gecko drops his tail, how to keep the right cage temperatures, ways to protect geckos from other pets, and where to find the best supplies.

First Things First: Using This Book

Leopard Geckos For Dummies is a reference, so you don’t have to read it in order from start to finish. Begin with Chapter 4 if you need basic set-up information, flip to Chapter 6 if you’re trying to understand leopard gecko behavior, or head to Chapter 2 if you’re still on the fence about adding a leopard gecko to your family. (Although those of you who prefer to start at the beginning and read until you reach the back cover are welcome to do so. I’ll never tell.)

As you read, keep an eye out for text in italics, which indicates a new term and a nearby definition — no need to spend time hunting through a glossary. You’ll also run into a few sidebars (the occasional gray box); although the information in the sidebars is good, it’s not essential to the discussion at hand, so skip ’em if you want to.

This small book is crammed full of information on leopard geckos, from how to decide whether this is the right pet for you, to choosing the right leopard gecko, caring for him, and even how to breed that pet in the future. This book can be your reference for many years to come. Just keep reading.

Taking a Look at Gecko Ecology

Geckos are lizards. They have four legs and are primarily (but not entirely) insectivores (they eat insects). However, those are about all the generalizations that can be made. Some geckos are ground dwellers while others live in trees. A few species of geckos live in arid deserts while others prefer more humid tropical environments. Most eat insects, but some also eat fruits and nectars. Many geckos are known for having sticky feet and the ability to walk straight up glass, but not all have this ability. Some geckos have immoveable eyelids while others do not. Geckos are amazing lizards, and it’s this variety that makes them so fascinating.

Charting gecko evolution

Geckos belong to the family scientists call Gekkonidae. Ancestors of today’s geckos thrived during the Jurassic period but unfortunately, fossils of such tiny creatures from that era are hard to find so their true evolution during that era is unknown. However, fossils have been found from the Eocene period (beginning 50 million years ago) that showed that the ancestors of today’s geckos were adapting to many different habitats. In addition, those changes were occurring as those habitats themselves were changing. During the beginning of the Eocene period, Australia and South America were still one huge continent. It’s amazing to realize that the ancestors of today’s geckos survived such world-changing events as the splitting and relocation of two major continents.

The family of geckos, Gekkonidae, belongs to the order (group) of lizards called Squamata, and the class called Reptiles.

Mapping geckos around the world

Geckos today are found in North America, South America, Central America, Africa, the Mediterranean regions, Madagascar, Asia, the Far East and many islands in the Pacific. Some of these populations evolved in those locations, but many more were transported there as people themselves traveled more. Sailing ships and the introduction of world trade spread many geckos to the four corners of the world. Some of these reptilian travelers died during the voyage, of course, and many others died in the new locations. But the ability of geckos to adapt to new conditions allowed enough to survive to establish new populations.

Today, geckos can be found in many different places:

Tokay geckos are from Southeast Asia; north through Japan and up to Korea. Introduced populations have been seen in Florida.

Tropical geckos (referring to their common name) originated in South Africa, and have been introduced and are thriving in Central America and other ports.

Mediterranean geckos are from Northern Africa and the Mediterranean region, and have been introduced and are thriving in North America and Mexico.

Reptiles are identified by a scientific name (such as Eublepharis macularius and a common name, leopard gecko. The scientific name is used for accuracy, and the common name is used for ease of pronunciation (and remembering!).

Just as geckos can be found all over the world, they can be found in a variety of habitats and climatic conditions. The banded geckos of the southwestern United States live in extremely arid deserts, just as the leopard geckos do in Pakistan and Afghanistan. Yet the green tree geckos of New Zealand live in densely forested areas with high humidity.

Understanding different gecko species

All geckos have a similar body type. The legs are short, the body cylindrical but squat, and the skin has fine scales that feel smooth to the touch. Many geckos species may also have some granular (bumpy) scales that are small smooth bumps while others many have scales that are tubercles (more pointy) or keeled (partially folded). The head is usually large in comparison to the body although some species (such as day geckos) have a more streamlined head.

Geckos are visual creatures, using their eyes to identify food and potential predators. Although many geckos will smell food before eating it, vision seems to be by far the most important sense. Those geckos who are diurnal (active during the day) have round pupils in the eyes, and those species that are nocturnal (active at night) have pupils with a vertical slit. The colors of the eyes, the irises, are often marbled in appearance, giving a very exotic look to the eyes. Some gecko species have moveable eyelids, but most have a transparent, fused eyelid that can protect the eye from minor injuries.

Geckos’ feet have long been a source of amazement. The ability of many gecko species to walk straight up a glass window (or side of a glass cage) is almost unbelievable. That ability comes from adhesive pads on the toes of the feet. When magnified, the pads can be seen as bristles made of keratin (like our fingernails), and the end of each bristle is split. These split bristles allow the gecko to adhere to a variety of surfaces, including glass, and to move under overhanging surfaces, such as under the eaves of houses. Geckos that are ground dwellers, such as leopard geckos and Madagascar ground geckos, have fewer of these bristles than do arboreal (live in trees) geckos, such as tokay geckos and green tree geckos.

Many geckos have some other interesting characteristics. For example, one species of the New Caledonian geckos and several Australian geckos will, when threatened, spray a foul-smelling liquid from his tail. There appear to be tiny glands between the segments of the tail, and the secretions can be sprayed as far away as 30 centimeters. Quite a shock to the predators hoping to make a meal out of these small geckos!
