Fast Earthworms

The video shows earthworms.They can be very fast if you scare them.Next I want to tell you a little about them
There are more than 6,000 earthworm species in the animal Kingdom of the planet. But why are they rainy?

Many people noticed that the sidewalks were covered with earthworms after the rain. Why do they do this? For a long time, scientists believed that they ran out of their tunnels to avoid drowning. Water saturates the ground during heavy rain, and the corridors made by our slimy friends are filled with water. No one wants to die like this.

But this is not quite true. It turns out that the earthworm has no lungs. It breathes through the skin and must remain moist to absorb oxygen. Ultraviolet rays are deadly to it. So today, researchers believe that worms come out of the ground to mate or migrate to another piece of land. After all, during the rain, they are guaranteed moisture! You may not have never known that:

1. Some earthworm species are hermaphrodites and have both male and female reproductive organs.

2. In 24 hours, one worm is able to produce the equivalent of its weight in excrement.

3. the Giant earthworm that lives in Australia can reach a length of 3 meters. This is a rare, endangered species. 4. The body of earthworms contains ten mini hearts.

5. for reproduction, earthworms find a pair, stick to each other and exchange sperm.

6. In the autumn, when the temperature drops, they burrow to a depth of one to two meters, where the ground does not freeze. There they remain inactive until spring.

7. Earthworms belong to the type of annelids, which have a higher system of organization than flatworms.
