Description
The Frilled Dogwinkle (*Nucella lamellosa*) is a medium-sized marine gastropod known for its highly variable and often ornate shell. It features prominent, wavy, and sometimes frilly axial lamellae (ribs) that give it a rugged appearance. The shell is robust, with a moderately elevated spire and a wide, oval aperture. Its appearance can vary significantly depending on environmental conditions, with more sheltered individuals often having more pronounced frills.
