Snakes employ various reproductive strategies to ensure the survival and success of their offspring. Some species, like the green snake, exhibit a phenomenon called "ovoviviparity," where the young develop inside the mother's body, absorbing nutrients from the yolk sac and eventually being born alive. Other species, such as the garter snake, give birth to live young, but may also exhibit "parthenogenesis," a process where unfertilized eggs develop into viable offspring.
