Habitat and adaptations

-Earthworms are found in many terrestrial environments ranging from semi-arid habitats to moist, well-vegetated areas.
-Some earthworms are found in wetter areas, or they can be found in soil, under logs, and usually come out of the soil after a heavy rain because it is becoming water-logged
-Most leeches are freshwater animals, but many terrestrial and marine species occur.
-Land leeches are common on the ground or in low foliage in wet rain forests. In drier forests they may be found on the ground in seepage moistened places. Most do not enter water and cannot swim, but can survive periods of immersion.
-Some species burrow in the soil where they can survive for many months even in a total lack of environmental water.
