This educational training aid had been used in a Natural Science class at a German school in Ludwickshafen am Rhein. It was frequently but carefully handled, and is in very good condition.

A bit of background. An earthworm is a tube-shaped, segmented worm found in the phylum Annelida. They normally live in soil, feeding on live and dead organic matter. An earthworm's digestive system runs through the length of its body. It conducts respiration through its skin. It has a double transport system composed of coelomic fluid that moves within the fluid-filled coelom 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, and their actions move the digesting food toward the worm's anus

The poster is 46 in. long X 37.5 in. wide. The depiction has a copyright dated in 1955; the poster itself had been printed in 1978.
