Exactly! Earthworms are a fascinating example of how nature can solve the problem of survival without lungs. However, their respiration is the reason we see them “running” on asphalt roads and sidewalks after every heavy rain.<\/p>\n\n\n\n
Here are some interesting facts about how this earthworm “skin system” works and why it is so vulnerable:<\/p>\n\n\n\n
\ud83e\uddec How does cutaneous respiration work?<\/p>\n\n\n\n
Earthworms don’t have lungs. Oxygen from the air (or water) dissolves in the mucus that covers their bodies. From there, it passes through the thin skin directly into the bloodstream. For this process to work, two conditions must be met:<\/p>\n\n\n\n
Moisture: If the skin dries out, the oxygen has nothing to dissolve in, and the earthworm paradoxically suffocates.<\/p>\n\n\n\n
Protective Mucus: Earthworms constantly secrete mucus, which not only makes breathing easier but also acts as a lubricant for moving through the soil.<\/p>\n\n\n\n
\ud83c\udf27\ufe0f Why Do They Come to the Surface After Rain? (Myth vs. Reality)
For a long time, it was believed that earthworms came to the surface to avoid drowning in flooded burrows. However, the reality is somewhat different:<\/p>\n\n\n\n
More Efficient Movement: While earthworms can survive in water for extended periods as long as oxygen is present, the moist surface of the soil allows them to travel greater distances safely without drying out. It serves as a “highway” for finding new food sources.<\/p>\n\n\n\n
Vibrations: Raindrops hitting the ground create vibrations similar to those of moles\u2014their greatest enemies. Therefore, moving to the surface is also a defense mechanism.<\/p>\n\n\n\n
\u2600\ufe0f Greatest Enemy: UV Radiation
Although they need moisture, direct sunlight is deadly to them. Earthworms not only dry out, but many species are also sensitive to light. Too much sun paralyzes them, preventing them from burrowing and making them easy prey for birds.<\/p>\n\n\n\n
\ud83d\udca1 Why are earthworms so valuable for your garden?<\/p>\n\n\n\n
Earthworm activity: Benefits for the soil<\/p>\n\n\n\n
Aeration: Their tunnels supply plant roots with oxygen.<\/p>\n\n\n\n
Drainage: They ensure that water penetrates deeper into the soil, thus preventing erosion.<\/p>\n\n\n\n
Worm compost: Their worm castings are one of the most nutrient-rich fertilizers in the world, rich in nitrogen, phosphorus, and potassium.<\/p>\n\n\n\n
Interesting fact: If you were to gather all the earthworms under one hectare of healthy meadow, they would weigh about as much as a fully grown cow.<\/p>\n\n\n\n
