CATDOLL : CATDOLL: What does it mean when earthworms react to water?

1. Scientific record: What will be the reaction of an earthworm if it is placed in water?

The earthworm will struggle in the water, but after a short while it will break into two pieces and eventually die.

2. Can earthworms swim? How will they react if you put them in water?

No, because earthworms breathe through their body surface and cannot contact air in water (they don't have gills). Haha, they will definitely drown if they soak for a while.

3. Why are earthworms afraid of flooding?

Earthworms absorb oxygen by contacting their skin with the air. They cannot absorb oxygen when they are wrapped in water. Unlike fish, earthworms do not have gills to breathe in water.

When they are in the soil, they rely on their skin to absorb trace amounts of oxygen in the soil gaps. When it rains, the small gaps in the soil will quickly fill with water, squeezing out the gas in the soil, resulting in no oxygen in the soil to supply the earthworms. So if the earthworms want to continue to survive, they will instinctively leave the soil and drill out of the ground.

4. Why do earthworms become soft when water is poured into them?

Because earthworms have no lungs or gills, they breathe through their skin, and their skin must be kept moist for oxygen to dissolve and enter the body. Therefore, they like to move in warm and humid soil.

However, earthworms will drown if they stay in water for a long time; in the same way, when it rains, the mud holes where earthworms hibernate are filled with water. If they do not crawl out of the ground, they will also drown.

5.Can earthworms enrich water?

Earthworms can nourish water

Earthworms are afraid of light, shock, immersion, salt, spicy food, cold and heat. Earthworms spit water because they are afraid and want to protect themselves.

Earthworms, commonly known as earth dragons or curved eels, are representative animals of the class Oligochaeta of the phylum Annelida. In scientific classification, they belong to the order Lumbricata. The body is cylindrical (different from the cylindrical shape of nematodes), bilaterally symmetrical, and segmented: it consists of more than 100 segments, and after the eleventh segment, there is a dorsal hole in the center of the back of each segment; it has no bones, is an invertebrate, has a naked body surface, and has no cuticle. Except for the first two segments of the body, the remaining segments have bristles. It is hermaphroditic and cross-fertilized. During reproduction, it produces egg cocoons through the annulus to reproduce the next generation. There are more than 2,500 known species of earthworms. Darwin pointed out in 1881 that earthworms are the most important animal group in the history of world evolution.

6. What happens when earthworms are placed in water?

Earthworms will struggle in water, but after a while they will break into two pieces and eventually die. If you put them in the soil and give them too much water, they will also die.

7. What does it mean when earthworms run into the water?

Indication of hypoxia

It is normal for earthworms to crawl into the water in large numbers. Earthworms breathe by relying on oxygen diffused from the atmosphere into the soil. The better the soil is ventilated, the better the metabolism of earthworms can be. On rainy days, rainwater will fill the pores of the soil, so it will be difficult for earthworms to breathe, which will cause a large number of earthworms to crawl out of the ground to breathe air.
