Description
A large, heavy marine gastropod shell, characterized by its robust and highly sculptured appearance. The shell is typically off-white to cream externally, often with brownish or grayish tones, and features a glossy, light orange-brown interior aperture. It is adorned with several rows of prominent, flattened, leaf-like spines or frills, particularly around the shoulder and along the outer lip, giving it a distinctive, ornate look.
