|And they're pretty too! |

Their many eyes have lenses and retinas, and are a lovely shade of deep greenish-blue.
Some of the best photos I've seen of those beautiful blues are over at David's Photo Blog; you'll see the eyes in a row lining the inside edges of both of the shells. Do go have a look-see.
A scallop's eyes can detect movement and changes of light and shadow. When they detect the presence of a sea star, a scallop doesn't just slam shut and hope the predator chooses someone else to pull apart. Instead, it leaps into action!
They can swim away by repeatedly clapping their shells, directing gulps of water out small openings on either side of their hinges, and moving jerkily forward. They look like swimming castanets, or, has often been suggested, two jaws biting their way through the water.
Oh yeah, and scallops are tasty, too. We humans usually only eat the round abductor muscle that holds the shells together, although I'm told that the rest of the animal is equally yummy. Do you suppose it's those baby blues that hold us back?
