How many segments does a earthworm have?
In an adult worm, there may be more than 100 segments.
How many nephridiopores are in each segment of the earthworm?
Except for the first and last segments, which have no setae, there are eight tiny bristle-like structures that can not be seen with the naked eye called setae on each segment of an earthworm. The arrangement of the setae is one factor that helps in the identification of earthworms, as they can be closely or widely paired in four pairs or separate. Setae grip the soil to help the earthworm move about and sense the enviroment.
How many parapodia are found per segment in earthworm?
Earthworms do not have parapodia.
How many setaes on one earth worms segment?

How do you describe segmentation in earthworms?
The earthworm is a segmented worm with a true coelom which is partitioned into separate segments. There are many internal structures that are repeated within each segment. Each segment is surrounded by both longitudinal and circular muscles allowing earthworms coordinated movement. The fluid filled coelom acts as a hydrostatic skeleton. Each body segment contains four pairs of chaetae, bristles that provide traction for movement. Also the first four segments make up the anterior head region of the external structure of earthworms. The first segment is the periostomium which bears the mouth and the anus is found in the last posterior segment. My reference is my Biology 191 laboratory manual on invertebrates. (pg's 77-78)
