Tucked into the mouth of Shem Creek, Crab Bank Island is one of Charleston Harbor’s most unique natural landmarks. Once lost to erosion, the island was restored as a protected seabird sanctuary and today serves as a vital nesting ground for pelicans, terns, herons, and other coastal birds. But Crab Bank isn’t just about conservation — it’s also famous for its fossil-rich sandbars and shark teeth, making it a must-see stop on any Charleston boat tour.

Shark Teeth & Fossils Near Crab Bank

For many visitors, Crab Bank is most famous for its connection to shark teeth and fossils. The waters and sandbars surrounding the island are part of Charleston’s fossil-rich coastline, where ancient shark teeth and other prehistoric treasures are often discovered.
Because Crab Bank itself is a protected bird sanctuary, guests cannot walk on the island or dig for fossils there. But as we cruise by, you’ll see the very sandbars and tidal zones that have made this area legendary among shark tooth hunters. It’s a chance to experience the same natural setting where countless collectors have made their finds.
Looking for a hands-on shark tooth adventure? Our dedicated Shark Tooth Tour is designed exactly for that. On this trip, you’ll explore other prime fossil locations in Charleston Harbor with one of our expert captains, increasing your chances of bringing home a real prehistoric souvenir.
