There are many species of earthworms. The largest, the true "night  crawler", was imported into this country.--probably in earth around shrubs and bulbs.  Twenty-two species have been found in Ohio, 10 of them some of the 19 species native to Denmark.  Thirty-seven species have been found in the British Isles. Some are quite small. Some live 10 or more years. They are composed of a large number of segments, or rings, each having four pairs of little bristles that enable them to crawl; and on the surface there are numerous small holes to the tiny kidneys and other organs. The mouth end is larger; the tail end flatter.
