This listing is for this specific gorgeous Lightning Whelk, which measures 7.5" in length and was self-collected from Florida's Gulf Coast - near Marco Island in 2024!   It has fabulous points!
 
This shell is an all natural, new find, and as such may have minor wear and variance.  It has had a bleach water bath but could use some mineral oil polish to suit!  
 
Thanks and Happy Shelling!
