The colloquial term "poisonous snake" is generally an incorrect label for snakes. A poison is inhaled or ingested, whereas venom produced by snakes is injected into its victim via fangs. There are, however, two exceptions: "Rhabdophis" sequesters toxins from the toads it eats, then secretes them from nuchal glands to ward off predators; and a small unusual population of garter snakes in the US state of Oregon retains enough toxins in their livers from ingested newts to be effectively poisonous to small local predators (such as crows and foxes).
