Due to the pollution of the marine environment, "red tides" occur frequently, which greatly increases the toxicity of "saxitoxin" in the snail.

After testing, the oral lethal dose of the toxin to human body is 1.54-1.9 mg, and a small snail is likely to cause death. Because the snail contains "saxitoxin" in its body, people will be poisoned by nerve conduction interruption after eating it, which can cause dizziness, vomiting, numbness of lips and fingers, and even death in severe cases, with the shortest incubation period of 5 minutes and the longest incubation period of 4 hours.
