Toxicity

While the term "poisonous snake" is often incorrectly used for a wide variety of venomous snakes, some species of Rhabdophis are in fact poisonous. Keelback snakes have glands that secrete poison they ingest from eating poisonous toads. While both venom and poison are toxins, a venom requires direct delivery, for instance subcutaneously through a snake bite, but can be ingested without harm. A poison can also be absorbed indirectly, e.g., by touch or through the digestive system.[1] At least some members of the genus, such as Rhabdophis subminiatus, are strongly venomous and are thus potentially dangerous to humans.[2][3]
