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.t eats dirt, digesting the plant and animal matter in the dirt and then eliminates the rest. It has an esophagus for the food to go down, a crop to store the food in, a gizzard that grinds the food down, intestines for the food to pass through and take out nutrients and an anus for the food to come out.
The setae are used for locomotion by the earthworm. Earthworms can be found in just about every corner of the earth. They live in trees, in bark, and under rocks as well as along rivers, near springs, and in ponds. Their favorite place to live, however, is burrowed inside the earthâs rich soil.epending on the environmental conditions, certain earthworm species may live anywhere from 4-8 years. The life span of an earthworm also depends on the number of predators the worm has to fend off each day.
