On rare occasions, gargoyle geckos can reproduce asexually via parthenogenesis. In their native habitat of southern New Caledonia, they have been known to sustain themselves from a mixed diet. One study [ 3 ] found that they regularly consume a wide taxonomic and ecological variety of arthropods , lizard prey including geckos and skinks, and ...
As well as this, sexually reproducing geckos are reported to be more robust and have higher survival rates than those which reproduce asexually. [12] There is a positive correlation between size and viability of eggs, with larger geckos having eggs which were more likely to survive.
Most geckos lay a small clutch of eggs. Some are live-bearing, and a few can reproduce asexually via parthenogenesis. Geckos also have a large diversity of sex-determining mechanisms, including temperature-dependent sex determination and both XX/XY and ZZ/ZW sex chromosomes with multiple transitions among them over evolutionary time.

Parthenogenesis is a mode of asexual reproduction in which offspring are produced by females without the genetic contribution of a male. Among all the sexual vertebrates, the only examples of true parthenogenesis, in which all-female populations reproduce without the involvement of males, are found in squamate reptiles (snakes and lizards).

They all wanted to find some unfamiliar-looking geckos — and they succeeded. From “slender” to spiky to “fringed,” researchers discovered dozens of new species of gecko in 2023. Take a ...
Obligate parthenogenesis is the process in which organisms exclusively reproduce through asexual means. [39] Many species have transitioned to obligate parthenogenesis over evolutionary time. Well documented transitions to obligate parthenogenesis have been found in numerous metazoan taxa, albeit through highly diverse mechanisms.
The visual system that the Geckos have is through corneal eyes similar to that of a human. [3] They are a nocturnal species which reproduce through Oviparous reproduction. Meaning that the species lays eggs outside of the mother as a form of reproduction. The gecko lays eggs in litters of 1 about 1-2 times per year.
Crested geckos mating. Little is known about the wild reproductive behavior of the crested gecko. Available information has been obtained from captive animals. Females generally lay two eggs per clutch, which hatch 60–150 days after they are laid. A female crested gecko only has to mate with a male once in order to lay 2 eggs every 4–6 ...
