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.
There are quite a few animals that have very strong stomachs. Fish have the strongest stomach being able to dissolve metal.

Digestion
Earthworms don't have spines, so their nerves don't travel through there.
The digestion system is about 6.5meters long in an average adult male.
yes, they have a complete digestive system with organs and a circulatory system with organs.
The component of the autonomic nervous system characterized by ganglia located in or near effector organs is the parasympathetic nervous system. This system is responsible for promoting "rest-and-digest" functions, facilitating processes like digestion and energy conservation. The ganglia in the parasympathetic system are typically situated close to or within the organs they innervate, allowing for localized control.
