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.
Total number of segments: 110-180
Seata per segment : 8
Except in the first two segments which builds the "head"
And the final 1 segment with anus have NO SEATAS.
The number of setae that earthworms have are 8 per segment. Most earth worms will have between 110 to 180 segments.
There are 6 segments in the Clitellum. Segments 32-37.
There are about 30 segments between the prostomium and clitellum of an earthworm.
An earthworm has two nephridia in nearly every segment.
There are 8 setae on each segment of an earthworm.
Around 14 to 16 segments
two on each

The small circular segment of DNA is called plasmid.
through aortic arches that function as many small hearts

You have one too many bases.
23 from each parent

Earthworms do not have parapodia.
they have 4 of them on each segment
Just the two of them at each end of the line segment.
Any line segment has infinitely many points and each one of them is specific to that line segment.
An earthworm has 5 eyes, that your answer!!!
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)
The earthworms has 4 seate's on each segment.
Millipedes have two pairs of legs per body segment.
It is seven (7) centimeters.
I want to say 2, once at each corner
Zero times.
