  • Skinks: With their sleek, smooth bodies and short legs, skinks make up a significant portion of some snake diets. There are more than 1,400 species of skinks, giving snakes a great diversity of prey.

Large Lizards

Although small to medium lizards make up a majority of the lizards eaten by snakes, there are instances where snakes have been known to prey on larger lizard species, such as:

  • Blue-Tongue Lizards: Native to Australia, these lizards are known for their bright blue tongues, used to scare off potential predators. However, this defense mechanism isn’t always sufficient to deter some larger, bolder snakes. Despite their larger size, these lizards can still be swallowed whole by snakes such as pythons or king snakes.
  • Komodo Dragons: It may come as a surprise, but even powerful predators like Komodo dragons can fall prey to snakes like reticulated pythons. While this is not a common occurrence, it demonstrates the impressive hunting capabilities of some snake species.

Snakes That Eat Lizards

Lizards are a common prey item for numerous snake species. In this section, we will discuss five types of snakes that are known to consume lizards regularly.

Garter Snakes

Garter snakes (genus Thamnophis) are small, non-venomous snakes found throughout North America. These snakes have a varied diet that includes:

  • Insects
  • Worms
  • Fish
  • Amphibians
  • Lizards

Garter snakes catch their lizard prey by using their excellent sense of smell and speed to ambush their target. Their diet varies by geographic location and the lizards available in their habitat.

Rat Snakes

Rat snakes (genus Pantherophis) are large, non-venomous constrictors native to North America and Asia. They are known for their rodent-hunting abilities, yet they also prey on other animals, such as:

  • Birds
  • Bird eggs
  • Frogs
  • Lizards

Rat snakes constrict their lizard prey and swallow them whole. In some cases, rat snakes consume lizards larger than themselves. The larger size and strength of these snakes give them an advantage over their lizard prey.

King Snakes

King snakes (genus Lampropeltis) include diverse species inhabiting North and Central America. Highly adaptable, they are known to consume a wide variety of prey, including:

  • Rodents
  • Birds
  • Bird eggs
  • Amphibians
  • Reptiles (including other snakes and lizards)

King snakes are constrictors that use their strong, muscular bodies to kill their prey, including lizards, before swallowing them whole.


Pythons (family Pythonidae) are non-venomous snakes from Africa, Asia, and Australia, which vary in size from small to massive. Though their primary diet consists of mammals and birds, some species are opportunistic predators, also consuming:

  • Amphibians
  • Fish
  • Lizards

Many python species are ambush predators, lying in wait to strike their lizard prey as it passes by.

Boa Constrictors

Boa constrictors (Boa constrictor) are large, non-venomous snakes native to the Americas. Their diet comprises a wide range of prey, including:

  • Mammals (such as rodents)
  • Birds
  • Reptiles (occasionally lizards)

These powerful constrictors ambush their prey and use their muscular bodies to suffocate it before swallowing it whole. Their size and strength make them formidable predators for lizards in their natural habitat.

In summary, a variety of snake species consume lizards as part of their diet. These snakes employ diverse hunting techniques and adapt their diets according to the available prey in their respective habitats, which often include lizards.

Geographical Distribution

In this section, we will explore the distribution of various snake species that are known to eat lizards across different continents.

North and Central America

In North and Central America, there are a variety of snake species that feed on lizards. Some examples include:

  • Pythons: Generally found in the southern region of the United States and Central America, they are known to consume different prey types, including lizards.

  • Racers: These are fast-moving snakes found throughout North and Central America, and they often eat lizards as part of their diet.

Impact on Lizard Populations

Snakes are one of the most common predators of lizards, and their feeding habits have a significant impact on lizard populations. The relationship between snakes and lizards is fascinating as it involves various aspects of predation, adaptation, and survival.

Predation by snakes can influence the distribution and abundance of lizards in specific habitats. For example, some lizard species may choose to live in areas with fewer snake predators to reduce the risk of being preyed upon. This can lead to changes in the structure of lizard communities, as well as their interactions with other species within their ecosystems.

Lizards have developed several defense mechanisms in response to snake predation. Some species rely on their speed and agility to escape from predators, while others use camouflage or display warning colors to deter potential attackers. Additionally, certain lizards are capable of detaching their tails, a phenomenon called autotomy, which allows them to distract and escape from predators.

Snakes also play a key role in maintaining balance within ecosystems by controlling lizard populations. This can be particularly important when it comes to managing overpopulation and preserving the health of habitats. In turn, lizards provide essential ecosystem services, such as the control of insects – including pests that affect crops.

Interestingly, the relationship between snakes and lizards can also lead to coevolution. This phenomenon occurs when two or more species reciprocally influence each other’s evolution through mutual interactions, such as predator and prey relationships. An example of this can be seen in the adaptive strategies developed by both snakes and lizards to improve their chances of catching and escaping from each other.

In summary, snakes’ predation on lizards has significant consequences for lizard populations, affecting their distribution, abundance, and community structure. The dynamic relationship between snakes and lizards serves as a prime example of the intricacies and interdependencies that drive the ecological balance within ecosystems.


In the vast world of reptiles, we come across various snake species that prey on lizards with different hunting techniques. Some examples of snakes that eat lizards are water snakes, king cobras, green anacondas, and gaboon vipers1.

Snake species like the water snake can be found living near water bodies and have developed a taste for cold-blooded creatures such as fish, frogs, and lizards2. Other snakes, such as the king cobra, ambushing their prey and delivering lethal venom to kill their lizard victims.

When examining the reasons behind snakes eating lizards, one could consider the nutritional benefits that lizards offer to their slithery predators3. It’s important to note that snakes are carnivorous predators and are not picky eaters. They will consume anything they can catch and swallow.

This includes:

  • Rodents
  • birds
  • frogs
  • lizards4.

FUN FACT: Some snakes are immune to the venom of other snakes5. Handy when consuming venomous lizards or dealing with fellow predator competition!
