The cockle uses its siphons to draw water into its body. This water passes through its gills, where the food particles are trapped. The food is then transported to the mouth and swallowed.
Atlantic cockles play an important role in the marine ecosystem by filtering the water and keeping it clean. They are also a valuable food source for humans and other animals.
