CATDOLL : CATDOLL: Will earthworms die if kept in water? Video tutorial (Complete video tutorial on will earthworms die if kept in water)

1. How long can earthworms live in water? Will earthworms die in water?

Earthworms cannot stay in water for a long time. Some can live for three days, while others can only live for three hours. Land earthworms use oxygen in the air, and their breathing depends on the body wall that can secrete mucus to keep it moist all the time. After a heavy rain, the gaps in the soil are filled with water, and the earthworms will crawl to the ground to breathe.

2. Will earthworms die if placed in water?

Earthworms will die in water.

Because earthworms do not have lungs and gills, they exchange gases through their body surface. Oxygen dissolves in the moist film on the body surface, then penetrates the cuticle and epithelium, reaches the microvascular plexus, and is combined with oxygen by hemoglobin in the plasma and transported to various parts of the body.

The earthworm's epithelium secretes mucus and the dorsal pore discharges body cavity fluid, keeping the body surface moist at all times. The skin must be kept moist so that oxygen can dissolve and enter the body. Therefore, they like to move in warm and humid soil.

However, earthworms will also drown if they stay in water for a long time. Similarly, 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.

3. Will you drown if you throw earthworms into the river?

Yes, after a heavy rain, you will find a lot of drowned earthworms in the waterlogged fields.

4. How long can earthworms survive in water?

Earthworms cannot stay in water for a long time. Some earthworms can stay in water for 3 days and continue to wriggle, while others can stay in water for only 2-3 hours. Earthworms prefer dark, moist and quiet environments, and are mostly concentrated in the surface soil within 20cm deep.

In terms of temperature, the activity temperature range is 5-30℃, and the suitable temperature is 20-27℃. In terms of food, it mainly feeds on dead grass, vegetable scraps, rotten leaves, melon and fruit peels, crop straw, etc. In terms of humidity, 40-60% is appropriate (soil humidity), not too dry or too humid.

5. What will happen if earthworms are left in water for a long time?

Earthworms cannot survive in water for a long time and will drown.

Earthworms mainly live in the surface layer of soil rich in organic matter. Earthworms are saprophagous, mainly feeding on decaying plants or other organic matter, and will swallow soil and sand to obtain the organic matter inside.

Earthworms do not have respiratory organs, but have a large network of microvessels distributed on their body surface. They breathe through gas diffusion on the body surface. Earthworms reproduce sexually and are hermaphrodites.

6. How long can earthworms survive in water? Will earthworms die in water?

Earthworms can live in water for more than 48 hours, which is amazing. I was very surprised at the time. Later, I conducted several more experiments and finally found the reason. It is because of the oxygen content in the water. The earthworms in the water with high oxygen content live for a long time, while the earthworms in the water with low oxygen content all die within a few hours.

Also, when you take out the earthworms that have stayed in the water for a long time, they look half-dead and not very energetic, but each one is alive. After taking them out, put them in the earthworm bed and cover them with a layer of soil, and they will recover in an hour.

7. 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.

8. Will snails and earthworms die if left in water for a long time? Why?

Earthworms: Earthworms do not have lungs or gills. They breathe through their skin, and their skin must be kept moist to allow oxygen to dissolve and enter their bodies, so they will die. Snails: Depending on their living environment, snails are divided into terrestrial and aquatic. However, even aquatic snails (such as the golden apple snail) can only stay underwater for a longer period of time. If they stay underwater for a long time, aquatic snails will still drown. In other words, snails cannot breathe underwater, and snails that cannot come to the surface to breathe will "drowned"!
