Why Do Earthworms Come Out In The Rain?
As a child who loved to play under the rain, you probably noticed how a lot of earthworms come out on the surface. Thinking that it is drenching wet under the ground, you probably thought that the reason why worms do is so that they won’t drown in the water if they stayed below. This is not true, but it is indeed a common myth that worms is just forced to come of their holes during the rain to find another place for shelter.
In truth, worms are actually capable of surviving under water. Since they breathe through the exchange of gas, they are basically able to absorb oxygen through their skins; meaning to say, if a body of water had stuffiest amount of oxygen, the worm is well likely to survive when placed in it.
So why is it that earthworms come out in the rain? Earthworms basically need a lot of moisture to survive in an environment. Notice how moist to the point of slimy their tubular bodies are. The reason why worms hide underground is to actually avoid the sunlight that can suck out the moisture from their bodies. When too exposed to too much heat, earthworms can actually die easily. In addition, since they breathe through their skin, it essential for them to keep moist to allow more absorption of useful oxygen.
Several other assumptions have been made as to why earthworms come out during the rain. There is the fact that worms like to find their mate above the ground, and there’s the other opinion worms come out of their burrow due to the shortage of oxygen circulation caused by the rain underground. By to sum everything, since the environment above the ground is often times to extreme for the worm, it is only after the rain that an environment conducive to their composition that worms are actually encouraged to go out of the surface.
