Lampreys belong to a class of ancient organisms, they have a part of the toxin retained. In the records, King Henry I of England was very fond of eating lampreys, many people believe that the king was poisoned because he ate too many lampreys, so he died. Of course, some people think that the death of Henry I has nothing to do with lampreys, because lampreys poisoning is only a rumor.
As mentioned above, there is a certain degree of toxicity in the body of lamprey. However, they are not very toxic, and the toxin is relatively weak after high temperature treatment. And because they have fewer thorns in their bodies, their meat is more delicious and tastes very good, so they are very popular. Lampreys are edible, and in fact many people choose to eat them. Small amounts are fine, and apart from Henry I, no one else has been poisoned by eating lampreys.
