CATDOLL : CATDOLL: Will earthworms die if kept in water? Why can't we keep them alive? (Will earthworms die if kept in water? Why can't we keep them alive?)

1. 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.

2. 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.

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. Can earthworms survive in a fish tank?

There are two reasons why earthworms cannot survive in fish tanks.

1 The fish tank is full of water and if there is no oxygen in the water, the fish will suffocate to death.

2If there are fish in the fish tank, the earthworms will be eaten by the fish.

So earthworms can't survive in fish tanks

5. 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.

6. Why can’t earthworms survive when thrown into water?

Earthworms don't have gills, so they can't breathe in water and therefore can't survive.

7. Why can’t earthworms live in water?

No, earthworms can only live in moist places. Moist does not mean in water. In water, they will die due to lack of oxygen.

8. Can earthworms survive in water?

Earthworms can survive in water. They are a kind of heteromorphic creatures that live in the soil and play a great role in loosening the land. They are not afraid of water and can survive after coming out of water.

9. Can earthworms live in water?

Earthworms live underground and feed on soil. If there is no soil in the water, they will starve to death and cannot live in water.
