Prostomium is the frontmost part of the earthworm. This is not called a
true segment as it doesn't contain typical organs of an annelida. Peristomium is from where the true segment of the earthworm body starts.
The esophagus of an earthworm is part of the earthworm's digestive tract, between the pharynx and the crop, and it basically just moves the earthworm's food from the pharynx to the crop. It also helps to keep the food from backing up (making the worm barf/throw up).
There are about 30 segments between the prostomium and clitellum of an earthworm. actually this question asked as differently as "How many segments are between the prostomium and clitellum of an earthworm?" see answer for this question.
