"The eyes of a queen scallop are dotted all around the edge of its mantle. The jewel-like effect is due to a reflecting layer or tapetum behind each eye. Scallop eyes contain two types of retina -- one responds to light, the other to sudden darkness, such as the shadow cast by an approaching predator. The scallop probably cannot interpret shapes, but can detect changing patterns of movement, such as moving light-dark changes." (Foy and Oxford Scientific Films 1982:118)
