Florida's two common tulip shells share a family and a silhouette. The pattern gives them away.
Both belong to family Fasciolariidae and share the smooth spindle silhouette. Colour pattern is the deciding factor.
| Feature | True Tulip | Banded Tulip |
|---|---|---|
| Scientific name | Fasciolaria tulipa | Cinctura lilium |
| Typical size | 3–7 in (up to 9 in) | 2–4 in |
| Surface | Cream with irregular brown streaks & blotches | Cream with a few crisp dark spiral bands |
| Aperture | Often orange to salmon | Cream to orange |
| Shoulder | Smooth, unridged | Smooth, unridged |
Rule of thumb: streaky and larger = true tulip; banded and smaller = banded tulip.
