1. 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"!

2. Scientific record: What will be the reaction of an earthworm when 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.

3. Why do earthworms die if left in water for a long time?

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

4. 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.

5. 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.

6. 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.

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

They will die if they stay in water for a long time. Because earthworms do not have lungs and gills, they exchange gases on their body surface. Oxygen dissolves in the moist film on the body surface, then penetrates the keratin membrane 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 epithelium of earthworms secretes mucus, and the dorsal pores discharge body cavity fluid. They often keep their body surface moist and their skin must be kept moist to allow oxygen to 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. By the same token, 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.

8. Earthworms can live in water, is that correct?

Wrong, earthworms cannot live directly in water

Earthworms cannot live in water. Earthworms are terrestrial animals. If they do not get enough oxygen in water, they will die. Earthworms' living environment Earthworms belong to the class Chaetopoda and the order Oligochaeta. They usually live in dark and moist soil 10-30 cm deep in moist, loose soil rich in organic matter. Especially in fertile gardens, vegetable gardens, cultivated land, ditches, rivers, ponds, channels and sewers near canteens.
