How do they reproduce?
San Francisco garter snakes initially mate during springtime and then again during fall. As they had already gathered for hibernation, they do not have to waste energy seeking mates. Female garter snakes give off pheromones to draw in adult males.
Dozens of adult males will come to at least one female. This mass of mating snakes is referred to as a mating ball.
Some adult males use trickery to confuse their competition. They will secrete female pheromones to entice different adult males closer to them as opposed to the girl. After the alternative adult males are away from the mating ball, the adult males posing as women will dart back to the female to try to mate.
Garter snakes are oviparous, which means that they usually bear live young ones. After mating, the females generally store sperm in their bodies till they need to fertilize their eggs. Garter snakes give birth to 20-40 babies at a time, and litter sizes can range substantially according to the size of the female.
