Knobbed Whelk
Busycon carica (Gmelin, 1791)
Georgia And New Jersey State Shell
The Knobbed Whelk is fairly common on S. Hutchinson Island beaches. It's not as common as the Lihgtning and Pear whelks but I've found some small/medium sized shells. Knobby Whelks usually open on the right similar to Pear Whelks.
