A scallop is a marine bivalve mollusc of the family Pectinidae. Scallops live in all the world's oceans. This is one of the largest families of living bivalves. There are over 300 living species of scallop. Their main adaptation is the ability to swim by clapping their valves together. In this way they escape from most of their predators. They have a good reputation as a food source.
