The above plate is a pictorial collage highlighting some of the morphological characteristics specific to one or more aquatic oligochaetes {exception: the picture in the lower right corner is of my Aussie colleague Adrian M. Pinder (Wanneroo, Western Australia) holding small specimens of Megascolides australis, commonly known as the giant Gippsland earthworm -- the largest terrestrial oligochaete thus far known in the world}.  This species averages 1 meter (39 inches) in length and 2 cm (0.8 inches) in diameter, but can reach a length of 3 meters (~117 inches).
