The Reproduction of the Hawaiian Mourning Gecko
Mating and Fertilization
The reproductive process of the Hawaiian Mourning Gecko involves both sexual and asexual reproduction. Male geckos engage in aggressive competition for mating opportunities. When a male successfully mates with a female, he transfers his sperm to her through specialized structures called hemipenes.
Interestingly, the female Mourning Gecko can store sperm for extended periods of time, allowing her to fertilize her eggs over a period of months. This adaptation enables the female gecko to lay multiple clutches of eggs, even if she hasn’t mated recently.
Egg Laying and Incubation
After a gestation period of approximately 45 days, the female gecko gives birth to fully-formed offspring. The newborn geckos are independent from birth and can immediately begin hunting for food.
Parental Care
Unlike many reptiles, the Hawaiian Mourning Gecko does not provide any parental care to its offspring. Once the eggs are born, the mother gecko shows no further interest in their well-being. The newborn geckos must rely on their innate instincts and survival skills to thrive in their environment.
