Description
A medium-sized scallop shell, displaying a classic fan-like shape with prominent radial ribs. The coloration is a striking combination of pale cream or yellowish-white with distinct purplish-pink to reddish-brown radial bands, particularly noticeable towards the umbo. The shell appears to be from a marine environment, found on a sandy or rocky shore.
