Earthworms are invertebrates, which means they do not have a backbone. In fact, they don't have any kind of bones, legs, eyes, or teeth. They feel wet, slimy, and squishy.
While earthworms do not have legs, they do have muscles. They have muscles that circle their body and muscles that go from one end to the other.
The circular muscles allow the worm to make its body wider or more narrow.
The longitudinal muscles can shorten or lengthen the worm's body.
Using their muscles, earthworms crawl by lengthening its front part and pushing forward through the soil.
Notice how skinny the worm looks when its front end moves forward. Remember that the longitudinal muscles push the worm forward and the circular muscles squeeze the worm's body inward. Working together, these different muscles move part of the worm forward. When this is happening, tiny bristles called setaeon the underside of the worm hold the rear part of the worm in place.
Once the front part has pushed forward, the front setae hold the worm in place and the rear setae turn loose. Now the worm is in position to pull its rear end forward.
Notice how fat the rear end becomes as the worm's circular muscles relax and its longitudinal muscles contract. The rings of the earthworm expand and contract much like the coils of a slinky.

If a man lets an earthworm go inside his penis what will happen to him and the earthworm?
Earthworms are VERY unique creatures, unlike any other insect, earthworms only eat fertalized substance, such as dirt and mud. They do not eat flesh, never have and never will. If a man were to let an earthworm go inside his penis, the earthworm will do no harm, it would simply just move around looking for food, since earthworms have to constantly keep eat to continue producing its semen and to stay alive. Of course, letting an earth worm inside a man's penis can be VERY dangerouse to him, but no harm to the earthworm, in other words, it would be opposite, it will actually be the earthworms ultimate strength and a weekness to the man. Sperm is made and stored in the epididymis of the male, and is actually made out of food (sugars), proteins, and enzymes to help aid in the fertilization. Of course, sperm may not me a tasty meal for the man, but its the ultimale steroid use for the earthworm. If the earthworm were to find the epidermis, it can actually attach its mouth inside it, meaning when ever the man is in a sexual translation or producing new sperm, the earthworm would be obsorbing it and actually eating it but using the proteins and enzyms to help it stay alive.
Can flying cause a rheumatoid arthritis flair-up?
It didn't when I flew on a 12 hour flight from London to Tokyo.The real problem is the size of airline seats which are impossible for any normal person to be comfortable in, let alone anyone with rheumatoid arthritis.A problem for people with RA is that they need too move their joints to keep them loose even when they are not in a period of rheumatic flare up, as to long a period without movement makes effected joints hurt.Take every opportunity you can to stretch your legs, this is a good move to avoid thrombosis as well
Does an earthworm decompose?
the same way any other organism does; it is consumed and therefore recycled by other decomposers when it dies. Earthworms are considered decomposers because they eat rotting or dead organisms and they essentially excrete the chemical nutrients that enrich soil so that plants can grow.

Earthworm locomotion is conducted by waves of muscular contractions. The contracted segments seize the soil by the claw-like setae. The process of alternating the contracted segment with the relaxed segment causes movement.
