Key Identification Features
- Seven thick, very distinct costae (spiral ribs) spiral around twelve to fifteen whorls.
- The snail’s soft body lives inside this hard outer shell, and features forked cephalic tentacles on its ventral side.
- The snail’s distinctive purple color acts both as camouflage in its environment and as an adaptation that improves its ability to obtain food, making it a more effective predator.
