For years scientists seemed to think the only reason why earthworms came to the soil surface after a good rain was to prevent drowning(溺死) in their water-filled holes in the ground. “This is not true as earthworms breathe through their skins and actually require wet in the soil to do so.” said Dr. Chris Lowe, Lecturer in Waste and Environmental Management. Earthworms are unable to drown like a human would, and they can even survive several days fully go under the surface of water. Soil experts now think earthworms surface during rain storms for migration(迁徙) purposes. “It gives them a chance to move greater distances across the soil surface than they could do through soil.” said Dr. Lowe. “They can’t do this when it is dry because of their wet requirements, but during unwatered conditions, life is certainly more difficult for a worm. “Earthworms dig deeper into the soil where it is wetter when conditions are dry,’’ said Professor Mary Ann Bruns. Another explanation is rain drop vibrations(震动)on the soil surface sounds similar to vibration of animals who eat or kill earthworms, like those of moles(鼹鼠). Earthworms often come to the surface to escape moles. “Rain can cause vibrations on top of the soil like mole vibrations.” said Professor Josef Gorres. “Similar to how earthworms move upwards and out of the way when mole vibrations are felt, they could move in a similar way for rain vibrations.” Similarly, humans create vibrations to bilk worms out of their holes in the ground. Earthworms use touch to communicate and interact. Exactly why earthworms have come to form groups is still being studied, but it is possible that worms gather to protect themselves.
