Warning Coral snakes belong to the same family as the highly venomous cobras, kraits, mambas, and sea snakes. Unlike vipers and pit vipers, coral snakes have fangs that are fixed in position on the front part of the upper jaw and cannot be folded back. Coral snake venom is strongly neurotoxic, affecting the victim’s nervous and respiratory systems, and bites can be fatal. Do not handle these snakes!
