How Do Mourning Geckos Reproduce?


Mourning geckos are fascinating creatures with unusual reproductive habits that have piqued the interest of scientists and reptile enthusiasts alike. Unlike most reptiles, they are parthenogenetic, meaning they do not require a male to reproduce. This makes them a unique and fascinating study for those interested in reptilian biology.

In this article, we will explore the reproductive behavior of mourning geckos, including their ability to reproduce asexually and the methods they use to fertilize their eggs. We will also discuss the challenges that come with studying these elusive creatures and the exciting discoveries that have been made about their reproductive strategies. So, get ready to delve into the world of mourning geckos and discover the secrets of their remarkable reproductive capabilities!

How Do Mourning Geckos Reproduce?

Mourning geckos, also known as Lepidodactylus lugubris, are small lizards that can reproduce asexually, meaning they don’t need a mate to reproduce. They are native to areas such as Madagascar, the Comoros Islands, and nearby coastal regions. In this article, we will explore the unique reproductive process of these fascinating creatures.

Reproductive Anatomy of Mourning Geckos

Mourning geckos have a unique reproductive system that allows them to reproduce without a mate. They possess both male and female reproductive organs, which means they can fertilize their own eggs. The female reproductive tract of a mourning gecko consists of ovaries, oviducts, and a cloaca. The male reproductive system is made up of testes, ducts, and a cloaca.

During the mating season, male mourning geckos will display their dominance by fighting with other males. Once the dominant male is established, he will mate with the female by using his hemipenes, which are located in his cloaca. The female will then lay eggs, which she will incubate until they hatch.

Benefits of Asexual Reproduction

One of the benefits of asexual reproduction in mourning geckos is that they do not need a mate to reproduce, which means they can quickly establish a population in a new environment. This is because a single female can produce multiple offspring without the need for a male. Additionally, asexual reproduction reduces the risk of genetic defects that can occur from inbreeding.

Disadvantages of Asexual Reproduction

However, asexual reproduction also has its drawbacks. Since there is no genetic diversity in the offspring, it can lead to a lack of adaptability to environmental changes. Mourning geckos that reproduce asexually are more vulnerable to diseases and parasites, which can easily wipe out an entire population.

Incubation of Eggs

After laying her eggs, the female mourning gecko will incubate them by wrapping her body around them. The eggs will hatch after approximately 60 days, and the baby geckos will be fully independent from birth. A single female mourning gecko can produce up to two eggs every four weeks, which can result in a population explosion if left unchecked.

Mourning Geckos as Pets

Mourning geckos are popular pets because of their small size and ease of care. They are also fascinating to watch due to their unique reproductive process. However, it’s important to note that they are best kept in groups, as they are social creatures. Additionally, their asexual reproduction can result in overpopulation, so it’s important to keep their population in check by either separating males and females or by limiting their breeding.

Mourning Geckos vs. Other Geckos

Mourning geckos are unique in that they can reproduce asexually, while most other geckos require a mate to reproduce. Additionally, they are smaller in size compared to other geckos, which makes them suitable for smaller enclosures. Mourning geckos are also more social than other geckos, which makes them great pets for those who enjoy watching their pets interact with each other.


Mourning geckos are fascinating creatures with a unique reproductive system that sets them apart from other geckos. Their ability to reproduce asexually allows them to quickly establish a population in a new environment, but it also makes them vulnerable to diseases and parasites. As pets, they are easy to care for and are best kept in groups.

Frequently Asked Questions

How do mourning geckos reproduce?

Mourning geckos are unique because they are parthenogenic, which means they can reproduce without a male. Females are capable of producing eggs that are genetically identical to themselves without any fertilization. These eggs will hatch into baby geckos without the need for a male to be present.

However, if males are present, they will mate with females and fertilize their eggs, resulting in genetic diversity in the offspring. Males can also store sperm, meaning they can fertilize eggs weeks or even months after mating.

At what age do mourning geckos start breeding?

Mourning geckos reach sexual maturity at around 6-9 months of age. Females can start laying eggs as early as 9 months old, while males can start mating at around 7 months old. It’s important to note that while mourning geckos can reproduce without a mate, it’s still recommended to keep males and females together to encourage genetic diversity in the offspring.

How many eggs do mourning geckos lay?

Mourning geckos typically lay 1-2 eggs per clutch, although they can lay up to 4 eggs in some cases. Females can lay multiple clutches throughout the year, with each clutch being laid every 4-6 weeks. It’s important to provide a suitable nesting site for females to lay their eggs, such as a small container filled with moist substrate.

How long does it take for mourning gecko eggs to hatch?

Mourning gecko eggs typically hatch within 45-60 days after being laid. The eggs should be kept in a warm and humid environment, with a temperature of around 80-85°F and a humidity level of 70-80%. It’s important to keep the eggs separate from each other to prevent any potential cannibalism among hatchlings.

How do you care for mourning gecko hatchlings?

Mourning gecko hatchlings are relatively easy to care for. They should be kept in a small enclosure with a temperature of around 75-80°F and a humidity level of 70-80%. They can be fed a diet of small insects such as fruit flies or pinhead crickets. It’s important to provide plenty of hiding places for the hatchlings to feel secure and reduce stress. As they grow, they can be moved into larger enclosures with appropriate heating and lighting.

What is PARTHENOGENESIS? (mourning geckos)

In conclusion, the reproduction process of mourning geckos is quite unique and fascinating. These geckos are parthenogenetic, which means they can reproduce asexually without the need for a male partner. This ability allows them to rapidly increase their population in a short amount of time.

During their reproductive cycle, mourning geckos lay eggs that hatch into female offspring. These offspring will then be ready to reproduce within a few months, continuing the cycle of asexual reproduction. However, when a male is present, sexual reproduction can occur, which can result in a more diverse and genetically varied population.

Overall, the reproductive process of mourning geckos is a testament to their adaptability and survival skills. Their ability to reproduce asexually allows them to thrive in environments where other species may struggle. It is truly fascinating to observe how these little creatures have adapted to their environment and evolved to ensure their survival.
