Is the southeastern crown snake poisonous or venomous?
Mildly venomous but not dangerous: the southeastern crown snake has enlarged rear teeth and a mild venom for its prey, and a bite causes at most local swelling, which is why many sources simply call it harmless. It is not a pit viper or coral snake, the only U.S. land snakes with medically dangerous venom. Clean any bite like a small wound.
