About Earthworms
''An earthworm is a tube-shaped, segmented worm commonly found living in soil, that feeds on live and dead organic matter. Its digestive system runs through the length of its body. It conducts respiration through its skin. An earthworm has a double transport system composed of coleomicfluid that moves within the fluid-filled coleom and a simple, closed blood circulatory system. It has a central and a peripheral nervous system. The central nervous system consists of two ganglia above the mouth, one on either side, connected to a nerve cord running back along its length to motor neurons and sensory cells in each segment. Large numbers of chemoreceptors are concentrated near its mouth. Circumferential and longitudinal muscles on the periphery of each segment enable the worm to move. Similar sets of muscles line the gut. Earthworms are   hermaphrodites. As aninvertebrate, it lacks a skeleton, but it maintains its structure with fluid-filled coelom chambers that function as a  hydrostatic skeleton. ''
