Snake Eggs Vs Lizard Eggs: What’s The Difference?

When it comes to reptile eggs, snakes and lizards are two of the most common. While they may have a few features in common, there are also some key differences between snake eggs and lizard eggs that can help you differentiate between them. Let’s take a closer look at these two types of reptile eggs.

Size and Shape

The most obvious difference between snake eggs and lizard eggs is their size and shape. Snake eggs are typically quite large and oval-shaped, while lizard eggs tend to be smaller and more cylindrical in form. For example, a female garter snake might lay 10 to 20 large, soft-shelled eggs that measure up to two inches long; whereas the much smaller skink or gecko would produce much smaller round or elliptical-shaped clutches with only one or two eggs per clutch. These tiny reptile eggs could measure less than half an inch in length.


Another difference between snake and lizard eggs is their texture. Snake eggshells often feel leathery or parchment-like to the touch, while lizard eggshells tend to be thinner and more brittle due to their smaller size. Additionally, some species of lizards actually lay soft-shelled thin-skinned “leathery” type eggs similar to those of snakes; however, this is relatively rare among lizards compared with snakes. Larger species such as iguanas can deposit hard-shelled thick leathery egg cases containing multiple smaller round-shaped thin shells inside which contain several tiny reptile embryos each.

Incubation Requirements

A third difference between snake and lizard eggs is their incubation requirements. Snakes typically lay their large parchment-like egg clutches into nest cavities where females must actively coil around them for warmth for extended periods of time during incubation until hatching occurs. On the other hand, lizards lay their much smaller rounder egg clutches in the soil near vegetation where they do not require any active heating from adults but instead rely on passive heating from mother nature during incubation until hatching occurs several weeks later depending on species and environmental conditions such as temperature fluctuations experienced at various times during incubation period(s).

Hatching Survival Tactics

Finally, another difference between snake and lizard eggs has to do with survival tactics employed by unhatched offspring immediately following hatching from each respective egg type: In short – newly hatched baby snakes employ active escape behaviors such as wriggling away quickly through foliage or tunnels when frightened or alarmed directly after hatching; whereas – newly hatched baby lizards (from much smaller thin shell clutches) employ passive avoidance behaviors such as freezing motionless in place when confronted by potential predators directly after hatching thus providing even more resilience against predation prior to dispersal from parental nesting sites shortly thereafter.

An In-Depth Comparison of Hatching Conditions for Snakes and Lizards

When it comes to hatching conditions for snakes and lizards, there are some distinct differences that it is important for reptile owners to understand. While both require a warm environment with proper nutrition and humidity, the requirements are not necessarily the same for each species. It is important to understand how these factors differ in order to ensure the best possible hatching conditions for your reptiles.

Temperature Considerations

The temperature requirements for snake and lizard hatchlings are quite different. Snakes typically need a higher temperature than lizards, requiring temperatures in the mid-80s Fahrenheit (30C). This can be accomplished with an incubator or by providing a heat source such as an infrared heat lamp or ceramic heater. For optimal hatching success, it is important to keep the temperature at this level consistently throughout the duration of incubation. On the other hand, lizards require lower temperatures, usually in the mid-70s Fahrenheit (23C). Again, this can be accomplished either with an incubator or by providing a heat source such as a low-wattage lightbulb or heating pad set on its lowest setting. Once again, it is important to maintain this temperature consistently throughout hatching.

Humidity Requirements

The humidity requirements for snake and lizard hatchlings also differ significantly. Snake eggs require high humidity levels of 70-80%, while lizard eggs require much lower levels of 40-50%. This is because snakes breathe air directly from their eggs during incubation which necessitates higher humidity levels in order to supply sufficient oxygen to the embryo. On the other hand, lizards do not require as much moisture as they absorb oxygen through their eggshells during development. Therefore, they can tolerate much lower humidity levels without any detrimental effect on their development. As with temperature requirements, maintaining consistent humidity levels throughout incubation is important for optimal hatching success regardless of species type.

Nutritional Considerations

When it comes to nutritional needs during hatching snakes and lizards have similar requirements; however, there are still some key differences that should be taken into consideration when preparing food dishes during this period. Generally speaking most reptile hatchlings benefit from receiving a diet that consists mostly of insects supplemented with small amounts of fruits and vegetables; however certain species may have specific dietary needs that should be taken into account when formulating meals for them during this period (e.g., some bonds such as ball pythons may require rodent feeders). Additionally, smaller species may require smaller food items than larger ones so keep portion sizes in mind when purchasing/preparing food items for your reptiles’ meals during this period too!

Hatchling Development & Behavior

Lastly, it’s important to remember that although there may be similarities between snake and lizard hatchlings developmentally speaking there are still considerable differences between them too! For example, snakes typically take longer than lizards to reach maturity (3-5 years vs 1-2 years respectively) and often display slower growth rates too; whereas many lizards will reach adult size within 6 months depending on species type! Additionally, snakes tend to display more solitary behavior whereas many lizards will choose group living environments if provided with ample space/territory/feeder availability, etc.


Whether you’re hatching snakes or lizards, it is important to take into account the various environmental and nutritional needs of your species in order to ensure optimal success. Temperature, humidity, and food items should all be carefully monitored and adjusted as needed throughout incubation. Additionally, understanding the differences between snake and lizard hatchling development can help you make more informed decisions when caring for these delicate creatures during their early life stages. With a little patience and dedication, providing an ideal environment for successful reptile hatching can become second nature!
