A earthworm does not have a skeleton. It has bristles on each segment called setae that help the earthworm move. Earthworms have no limbs. The earthworm has two sets of muscles; one that makes it long and thin and one that makes it fat.

Because he has worms in his system. Get him to a vet.
Flatworms have a cephalized nervous system that consists of head ganglion, usually attached to longitudinal nerve cords that are interconnected across the body by transverse branches. Source:http://animaldiversity.ummz.umich.edu/site/accounts/information/Platyhelminthes.html

No, worms do not have a stomach--they do have a crop and a gizzard, as part of the digestive tract. The mouth of the worm connects directly to this tract, which runs the entire length of it's body.
