Is the lightning whelk a rare shell?

The lightning whelk is not considered a rare shell; it is relatively common along the Gulf of Mexico and the southeastern Atlantic coast of the United States. Its distinctive spiral shape and striking pattern make it a popular find among shell collectors. However, local populations can fluctuate due to environmental factors and human activity, which can impact their availability in certain areas. Overall, while it may be sought after, it is not classified as rare.
