Diets vary among species but include slugs, earthworms, fish and amphibians. Mammals are eaten occasionally, especially by the western garter snake (T. elegans), which restrains such prey by a primitive coiling behaviour. All are live-bearing and normally produce 5-25 young by mid- to late summer but much larger litters are reported occasionally.
