Queen Helmet Large Shell, Cassis madagascariensis. This species occurs in the tropical Western Atlantic. The specific name "madagascarensis" literally means "of Madagascar", but this was a misunderstanding of the type locality by the original author. Live specimens of this helmet species can occasionally be found about 30 feet out in the ocean. Because they live so far offshore, the best time to find these shells is at low tide after a storm.
