Not all snakes lay eggs- some have live young. The three pit vipers (Copperhead, Cottonmouth, Rattlesnake) have live babies that are on their own immediately after birth and equipped with fangs and venom to apprehend prey and protect themselves. The Texas Coral Snake lays three to four eggs in spring.
The number of young varies from 1 to more than 100,
depending on the species and individual. Most species of snakes lay
eggs. Depending on the species, a female snake may lay as few as 6 eggs or as many as 100 eggs at one time.
Only 70 percent of the world's snakes lay eggs. The rest give birth to live young. Oviparous—or egg-laying—snakes tend to live in warmer climates, which helps incubate their eggs. Viviparous—or live-birthing—snakes tend to live in cooler regions, where the ground is too cold for the eggs to develop on their own.
