Upon being donated to the Museum, it can be found jumping around in the large tank in the first room of the ocean exhibit. The exhibit says this about the Scallop:

"Scallops inhabit the cool ocean bed. They swim by rapidly clapping together their shell valves. The black dots on scallops, known as wavy "strings", are actually their eyes. These eyes number over 80 but only really function as a means to sense light rather than motion. Often grilled or buttered, scallops have become a tasty seafood enjoyed all over the world."
