how long do garter snakes get
And their appearance really does depend on the species â Beane pointed out that some garter snakes are âvirtually stripeless.â. Garter snakes are relatively small, usually between 23 and 30 inches (58 and 76 centimeters), though sometimes growing as long as 5 feet (1.5 meters).Beane described them as âslender to moderately stout-bodied ... [with scales that are] obviously keeled,â meaning they have a ridge down the center.arter snakes are ovoviviparous, meaning they bear live young. After mating, females store sperm in their bodies until they want to fertilize their eggs. Garter snakes give birth to 20 to 40 live young at a time, though Beane pointed out that litter sizes can vary greatly.
