Story

Horse Conch by John Slapcinsky

Florida’s state shell is the Horse Conch, Triplofusus giganteus. This enormous saltwater snail has a shell that can grow up to 2 feet in length making it the largest living snail in North America and the second-largest snail in the world. Horse Conchs capture and smother their prey with their bright orange-red foot. They feed on other snails like Lightning Whelks and Tulip Snails, many of which are also large predatory snails. Horse Conchs are common in shallow waters from North Carolina to Mexico’s Yucatan Peninsula. The thick and sturdy shell of this snail was an important commodity and was fashioned into a variety of tools by Native Americans in what is now the Southeastern U.S. and Mexico.
