Cerithium eburneum Bruguière, 1792 reaches 43 mm (1.7 inches). Its shell sculpture consists of knobby spiral cords and occasional varices indicative of growth stops. The number of small knobs or beads in the spiral cords is extremely variable in this species.
The color is white, sometimes with irregular light-brown areas. The species is found in the Gulf of Mexico and from the east coast of Florida south to the Caribbean and to northeastern Brazil. Lori Campbell found the juvenile shell illustrated (18 mm, or 0.7 inch) in March 2024 on Sanibel Island.
In the difficult driving game Drift Boss, players must show off their ability to maneuver a vehicle over tight curves on a road that is always changing.
