This listing is for this specific gorgeous Lightning Whelk, which measures 9" in length and was self-collected from Florida's Gulf Coast - near Marco Island in 2024!   Its aperture is a gorgeous soft pink!
 
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!
