The pilgrim’s scallop is a marine bivalve mollusc that belongs to the family Pectinidae. It is found in all the world’s oceans and its flesh is edible. It can swim large distances and is able to open and close its valves. Pilgrim’s scallops mainly feed on marine organisms. They reproduce by external fertilisation. They have fan-shaped shells that grow to a diameter of 12 cm. The shell’s interior contains the animal’s body, which is covered by a mantle with tentacles along its edges. These contain its sensory organs (for feeling and smelling).
