Initially, over 100,000 earthworm larvae were collected, but earthworms have a small characteristic: they can survive even after being cut in half.
Earthworms are a special type of segmented animal. They have a head and a tail and specific organs.
However, their entire body is like two tubes wrapped together, with an outer layer containing the muscle system inside. Running through its body is the digestive tract, which contains many body cavity fluids.
When an earthworm is cut into two parts, its muscle tissue begins to contract, allowing some cells to automatically dissolve and form new cell clusters.
As a result, the cut surface is blocked, ensuring that not too much blood is lost from the wound on its body.
Once the wound heals, muscle cells begin to migrate, forming regenerative buds and growing new parts.
Of course, not all earthworms can regenerate after being severed. There is a luck factor involved.
