How long is the longest earthworm in the world? It is the most valuable animal on earth!

Earthworms are invertebrates with cylindrical bodies and more than 100 body segments. There are many kinds of earthworms. At present, there are more than 2500 kinds of earthworms with different body lengths. The common earthworms are 90ml 150mm in length. So, how long is the longest earthworm in the world?

How long is the longest earthworm in the world?

1. The world's longest earthworms are giant earthworms, a huge subspecies of vermis that lives in South America. According to biologists, they may have existed during the dinosaur period, although they are called by this name. but it is very different from the kinship of earthworms.

3. Giant earthworms are said to be more than 2 meters long, which is longer than ordinary long snakes. On July 19, 2014, a giant earthworm was discovered near the Sumaco volcano in Ecuador. It is about 5 feet long and weighs at least 1.12lbs. It is similar in size to a snake.

4. Giant earthworms mainly live in the forests of South America, and they can also be found in Australia, with an average length of more than 1 meter, a diameter of about 2cm-4cm, a weight of 500-700g and a life span of more than 5 years.

Why are earthworms the most valuable animals on earth?

Darwin pointed out in 1881 that earthworms are the most important animal group in the history of world evolution and an organism symbolizing the quality of the soil. if there are no earthworms in the soil, it means that there is something wrong with the soil, so earthworms are the most valuable animals on earth. What's its value?

2. Increase organic matter and improve soil structure: earthworm manure is rich in inorganic salts such as nitrogen, phosphorus and potassium, which can increase soil organic matter, improve soil structure, promote acidic or alkaline soil to become neutral soil, and increase available components such as phosphor. make the soil suitable for the growth of crops.

3. Eat garbage and discharge fertilizer: earthworms are omnivorous animals. Except for glass, plastic and rubber, the rest, such as humus, animal faeces, soil bacteria, fungi and the decomposition products of these substances, are eaten, and do not bite the roots of plants; the amount of food eaten every day is equal to one's own weight, about half of which is excreted as feces, and the excrement is a good fertilizer.

4. Change the spatial distribution of soil organic matter: earthworm activity can change the spatial distribution of soil organic matter, make soil organic matter in patchy distribution, and mix organic matter with mineral soil to form soil particles rich in organic matter; its activity facilitates the downward movement of phosphorus, which improves the patch distribution of phosphorus in the soil; its activity consumes a large number of soil microorganisms and increases the concentration of soil mineralized nitrogen.

The above is the longest earthworm and value introduction in the world. I hope it will be useful to you.
