Does snakes reproduce sexually or asexually? Most reptiles of the squamatan order (lizards and snakes) reproduce sexually, but parthenogenesis has been observed to occur naturally in certain species of whiptails, some geckos, rock lizards, Komodo dragons and snakes.
How do snakes reproduce? Snakes reproduce by internal fertilization and either give birth to live young or lay eggs, depending on the species. Female live-bearing snakes will find a sheltered location to give birth before abandoning the young to fend for themselves.
Can snakes have babies without mating? In rare cases, a snake may lay a clutch of eggs without mating, which are infertile if she isn’t able to fertilize them herself.
