First Aid for CONE SNAIL or SHELL PUNCTURES
Most cone snail punctures in Hawaii are not dangerous, and require no specific treatment other than thorough scrubbing of the wound. Rarely, however, a person stung by a cone snail experiences nausea, headache, or difficulty breathing. If any of these symptoms develop after a sting, go directly to an emergency room. In route, hold the bite site below the rest of the body, while keeping the victim as still as possible. Apply a broad pressure bandage over the bite about as tight as an elastic wrap to a sprained ankle. This slows the venom's spread through the lymph system. Make sure arterial circulation is not cut off by making sure fingers or toes stay pink and warm.
If possible, bring the stinging snail to the emergency room, being careful not to get stung again.
