California Redsided Gartersnake

Eats a wide variety of prey, including frogs and newts and their larvae, fish, birds, and their eggs, small mammals, reptiles, earthworms, slugs, and leeches. When Gartersnakes eat Rough-skinned Newts they retain the deadly neurotoxin found in the skin of the newts called tetrodotoxin for several weeks, making the snakes poisonous to predators that eat the snakes.
