The San Francisco garter snake has a wide geographic range within California and is known to inhabit both freshwater and terrestrial habitats.
This species often makes use of its highly developed sense of smell to locate prey items. It will also use its tongue to detect scent molecules in the air. Once a potential food item has been detected, the snake will strike out with lightning speed in order to capture its prey. Once captured, the snake will usually kill its prey quickly by constriction or biting it with its sharp teeth. After consuming its meal, the San Francisco garter snake may bask in order to digest it fully before moving on in search of another meal.
In addition to being opportunistic feeders, this species may also engage in cannibalism if food resources are scarce or if competition for food becomes too great. While this behavior is not common among this species, it may occur occasionally when other food sources are not available or accessible.
