When the scallop’s shell is gaped you can see two rows of tiny, bright blue eyes. These eyes aren’t the simple light sensitive eyes that most mollusks have, they can also sense motion. So a crab or fish trying to sneak up on one and grab some flesh before the shells close will be seen before it gets even close. And if the scallop loses an eye it simply regenerates a new one in its place.
