Earthworms do not possess a stomach. Instead, their digestive system includes a crop for storing food and a gizzard for grinding it, allowing them to process organic matter without the need for a dedicated stomach. This adaptation helps them efficiently break down and absorb nutrients from the soil they ingest.
