Scallop
Most scallops are filter feeders. They eat plankton. The plankton sometimes has scallop larvae in it. Siphons bring water over a filtering structure. Mucus then traps the food. Next, the cilia on the structure moves the food to the mouth. Then, the scallop digests the food in the stomach and digestive gland. Waste goes through the intestine and exits through the anus.
