To continue the ocean theme I seem to be on – small sketch of Scallop Shells from a photo on the internet. Scallops are a cosmopolitan family of bivalves, found in all of the world’s oceans, though never in freshwater. They are one of very few groups of bivalves to be primarily “free-living”; many species are capable of rapidly swimming short distances and even of migrating some distance across the ocean floor. The majority of species, however, live recumbent on sandy substrates, and when they sense the presence of a predator such as a starfish, they are able to escape by swimming swiftly but erratically through the water using a form of jet propulsion created by repeatedly clapping of their shells together.
