Depending on the species, an adult earthworm can be from 10 mm (0.39 in) long and 1 mm (0.039 in) wide to 3 m (9.8 ft) long and over 25 mm (0.98 in) wide, but the typical Lumbricus terrestris grows to about 360 mm (14 in) long.
The bodies of most oligochaetes (earthworms) are divided externally and internally into well-defined segments. Internally, these segments are divided by membranous partitions. Except for the most anterior and posterior segments, all segments are essentially alike. Earthworms burrow through the soil, feeding on decaying leaves and animal debris. As earthworms move through the soil, they both enrich and loosen the soil. It is for this reason that earthworms are valued by gardeners. An acre of good garden soil may contain as many as 50,000 individuals. External Anatomy and Locomotion of the living earthworm Observe the external features of the earthworm. Notice that the body is made up of a number of segments.
