The reptile world is vast and varied, and within it lies the order Squamata, which encompasses both lizards and geckos. Though related, these creatures are far from identical.
So, what sets a gecko apart from other lizards? This article will explore the key differences between these fascinating reptiles.
We’ll look at their unique appearances, preferred habitats, dietary habits, average lifespans, and reproductive strategies. By the end, you’ll have a solid understanding of the defining characteristics of both lizards and geckos.
What Defines a Gecko and a Lizard?
Both geckos and lizards belong to the reptile order Squamata, which is characterized by scaled skin, but that’s pretty much where the similarities end.
Geckos
Geckos belong to the family Gekkonidae, but what really sets them apart from other lizards are their adaptations, such as toe pads that help them climb smooth surfaces. Geckos are also known for their diverse vocalizations, from chirps to barks.
Lizards
Lizards belong to the suborder Lacertilia, a more diverse group than geckos. Lizards come in a wide range of sizes and shapes, with all sorts of adaptations. Not all lizards are geckos, but geckos are lizards.
Gecko vs. Lizard: Appearance and Physical Characteristics
Although geckos are a type of lizard, they have a few features that set them apart.
Gecko Appearance
Most geckos are small, about 7 to 12 inches long, and many have bright colors and patterns. They’re known for their amazing ability to climb smooth surfaces, thanks to special toe pads. Some geckos can even change color to blend in with their surroundings. And like many lizards, some gecko species can shed their tails when threatened, later regrowing them.
Lizard Appearance
Lizards are a diverse group, so their appearance varies a lot. They range in size from tiny, inch-long creatures to giant, 10-foot-long reptiles like the Komodo dragon. Unlike some geckos, lizards usually have eyelids. While some lizards are brightly colored, many sport shades of brown and gray.
Where do geckos and lizards live?
Geckos like it either dry or humid. You’ll find them in tropical and subtropical regions all over the world.
Lizards are more adaptable. They live on every continent except Antarctica. You might spot them scurrying across the desert, hiding in a forest, or sunning themselves in a grassy field. Lizards have adapted to just about every environment imaginable.
Gecko vs. lizard: Diet and eating habits
When it comes to mealtime, geckos and lizards have slightly different habits.
Gecko diet
Most geckos are insectivores, which means insects make up the bulk of their diet. Geckos tend to hunt after dark.
Although most geckos dine on insects, some species are omnivores, and others are carnivores. The Caledonian gecko, for example, is known to eat young lizards, mice, and even small birds.
Lizard diet
Lizards tend to be less picky eaters than geckos. Their diet can include insects, plants, small mammals, and even other reptiles.
The Komodo dragon, for example, is a carnivorous lizard that can take down prey as large as a water buffalo.
Gecko vs. Lizard: Reproduction and Lifespan
Geckos and lizards both have interesting ways of reproducing, and their lifespans can vary pretty dramatically.
Gecko Reproduction and Lifespan
- Geckos typically lay one or two eggs in a clutch.
- Some gecko species lay eggs in pairs several times in one year.
- The average lifespan for a gecko is 5 to 15 years.
Lizard Reproduction and Lifespan
- Lizards have a wider range of reproductive methods, from laying eggs to live birth.
- Certain lizard species lay clutches containing more than five eggs.
- Lizard lifespans vary quite a bit, depending on the species, from just one to three years to several decades.
Geckos and lizards as pets
If you’re looking for a reptile pet, both geckos and lizards make good choices, depending on your lifestyle and willingness to provide care.
Popular gecko pets include leopard geckos and crested geckos. Some common lizard pets are bearded dragons, iguanas, tegus, and monitor lizards.
Each species has its own unique needs for food, habitat, temperature, and humidity. Make sure you’re ready to provide the right environment before you bring one home.
Frequently Asked Questions
Are geckos lizards or salamanders?
Geckos are lizards, not salamanders. Salamanders are amphibians, while lizards are reptiles. Geckos belong to the infraorder Gekkota, which falls under the order Squamata – the same order that includes all other lizards and snakes. So, while they’re unique lizards, they’re definitely not salamanders.
Is a gecko a lizard or a gecko?
This question is a bit of a wordplay! A gecko is a lizard. “Gecko” is simply the specific name for a group of lizards with distinct characteristics. It’s like asking if a golden retriever is a dog or a golden retriever. It’s both! All geckos are lizards, but not all lizards are geckos.
How to identify a gecko?
Geckos have distinct features that make them easy to identify. Look for their specialized toe pads with lamellae, which allow them to climb smooth surfaces. Their eyes often lack eyelids, and they use their tongues to clean and moisten them. Many geckos are nocturnal and have vertical pupils. Also, listen for their characteristic clicking or chirping sounds. These features, especially the toe pads, are your best bet for spotting a gecko.
Final Thoughts
Geckos and other lizards differ in several key ways, from their eyelids and feet to their activity patterns and vocalizations. Both groups of reptiles have evolved unique adaptations that allow them to thrive in their specific environments.
It’s important to remember that geckos are lizards, just a highly specialized type. Their sticky toe pads, nocturnal habits, and vocal abilities set them apart from other members of the lizard family.
Whether it’s a gecko clinging to a wall or a monitor lizard patrolling the forest floor, these reptiles play a vital role in the ecosystems they inhabit, and they deserve our appreciation.
