Description
The Zigzag Scallop is a bivalve mollusk known for its distinctive fan-shaped shell. The image displays two shells, likely the right (lower) valves, which are typically more convex and vibrantly colored, resting on a sandy beach amidst other shell fragments and seaweed. The prominent radial ribs are clearly visible, giving the shell a corrugated appearance.
