Snakes employ two primary reproductive strategies, each providing a distinct environment for the developing embryo. Oviparous snakes, representing the majority of species, lay eggs that contain the developing embryos.
If youve ever wondered why some females lay eggs while others give birth to live young, or how a snakes body gets ready for the season ahead, understanding snake breeding cycles reveals a world of adaptation and strategy.

Learn about snake reproduction, including mating behavior, reproductive anatomy, egg development, nesting, parental care, and offspring survival.

Learn when snakes have babies, from egg-laying species like corn snakes to live-bearing types such as garter snakes. Explore their mating seasons, breeding strategies, and crucial environmental factors influencing reproduction.

Snakes exhibit a remarkable diversity in reproduction, utilizing three distinct strategies to bring their young into the world. The answer to whether a snake lays eggs or gives birth to live babies is definitively both, depending on the species.
Here, we used 338 eggs from 32 clutches of the water snake Natrix maura to (1) thoroughly describe natural clutch arrangement, (2) experimentally assess the effects of natural embryo positioning and (3) egg turning on embryo metabolism, hatching success, and hatchling phenotype.
