Do Worms Have Teeth?

Worms have no teeth. They use their strong, muscular mouths to swallow pieces of leaves and dirt. The mouth is behind the firm and pointed prostomium, which is the front end.

The swallowed food goes through the pharynx and the esophagus and finally into the crop, where food is temporarily stored. From the crop, the food enters into the worm's gizzard, which is named such because of its muscles. Food is ground here before entering into the worm's intestine, which is over two-thirds of its body length. Broken-down food that is beneficial enters into the worm's bloodstream, while the unwanted remnants are removed from its body as worm feces or castings.
