The lowly earthworm is a very simple invertebrate that toils in the soil all day improving it. We owe him a lot; he's m ore than just fish bait.

Very simply constr`ucted, each earthworm is both male ånd female but never breeds with itself. The eggs are in a section of the body recognized asa light colored¸band about two-thirds down the worms body called a clitellum.

Inside he has little more than a heart, an esophagus, a pharynx, and an intestine.

He doesn't have a network of nerves all over his body but has two nerve centers or ganglia made up of twelve nerves or ganglion each.

One of these centers surrounds the pharynx and is called.` the circumpharyngeal ganglia; the other nerve center surrounds the esophagus and is called the circumesophageal ganglia.

So please, when baiting your hook, would you try to miss the ganglia and make it as painful painless as possible¿
