Komarekiona eatoni, or the Kentucky earthworm, is a vulnerable species of nearctic Annelid. K. eatoni is found in the southwestern United States , especially near the Appalachian Mountains , though they range at least northwest to Illinois and northeast to Maryland .
Both male and female reproductive organs are present in earthworms because they are monoecious. To breed, two earthworms exchange sperm. Long after they are separated, the egg case is secreted. It forms a ring around the worm, then the worm removes the ring from its body and injects its own eggs and the other worm's sperm into it.

Some species of earthworm can even use the prehensile prostomium to grab and drag ...
Oligochaetes are well-segmented worms and most have a spacious body cavity (coelom) used as a hydroskeleton.They range in length from less than 0.5 mm (0.02 in) up to 2 to 3 metres (6.6 to 9.8 ft) in the 'giant' species such as the giant Gippsland earthworm (Megascolides australis) and the Mekong worm (Amynthas mekongianus).
The New Zealand earthworm was first described by Frank Evers Beddard in 1885. [1] It is the type-species and type-genus of Octochaetidae, a family of earthworms mainly confined to the Australasian region, with the long anticipated "missing-link" between octochaetids in New Zealand and India found recently with Octochaetus ambrosensis (Blakemore, 1997) and its allied taxa in Australia.

In some areas where it is an introduced species , some people consider it to be a significant pest for out-competing native worms.
There are over 22,000 living annelid species, [6] [7] ranging in size from microscopic to the Australian giant Gippsland earthworm and Amynthas mekongianus, which can both grow up to 3 meters (9.8 ft) long [7] [8] [9] to the largest annelid, Microchaetus rappi which can grow up to 6.7 m (22 ft).
