About Oliva incrassata (Lightfoot), 1786
The shells of Oliva incrassata grow between 32 and 95 millimetres (1.3 to 3.7 inches) long. These are relatively large shells that are nearly cylindrical in shape, very thick, ovate, and characteristically angularly swollen at the middle. They have a fairly short spire, a narrow, long aperture, and typically have uniformly colored body whorls apart from the columellar area. The basic background color of the shells ranges from ash-white or greyish to light yellow and brown. Shells are mottled with gray and olive, and marked with angled transverse dark chestnut streaks, while the columellar area is a fleshy rosy pink. Oliva incrassata is distributed across a wide range extending from California to Peru. These sea snails inhabit the low-tide level on the outer side of sandspits.
