Description
Small, robust, and highly sculptured marine gastropod shell, characterized by prominent axial ribs and spiral cords that often form nodules or short spines. The shells in the image are beach-worn, showing variations in color from light tan to reddish-brown, and are typically found among pebbles and shell fragments in tropical coastal environments. While 'Risomurex nicocheanus' is the provided name, it is likely a misspelling or variant of the formally recognized species *Risomurex nicobaricus*.
