This can be caused by the availability of resources or the desire to avoid mating with close relatives. Worms often move on the surface in less harsh environmental conditions where the temperature and humidity are sufficient. This is not the case because terrestris, like other earthworms, live in oxygen-rich water for long periods of time and can last for weeks. This form of activity is often seen as a way to escape floods and soaked caves. Such movements are apparent during and after heavy rains and usually occur when people notice a relatively large number of earthworms, for example in urban ecosystems. Surface movements on moist, flat terrain have been reported at velocities of 20 m / h, with nocturnal activity outside burrows during a single surface advance of up to 19 m, based on path length measurements. SETAE-Correspond to the surrounding ground-like protrusions like small hair. The worm has a hydrostatic backbone and travels through longitudinal and circular muscle contraction. Deep brown next to reddish brown and the back declining to his back. The body is cylindrical with the body, except for the rear and flattened back. It has about 12017 segments, often 135150.
