Todd tossed the insect into the prepared mica culture dish, bandaged Cosette's wound, then slumped to the ground and let out a long sigh of relief.
Entrusting the task of caring for the girl to Rachel, Todd, along with the electric parasite, plunged headlong into the laboratory.
Through dissection and microscopic observation, Todd discovered a new species of parasite that he had never seen before.
This parasite has a body structure consisting of four layers. The outermost layer is a keratinous layer that secretes insulating mucus. The second layer from the outside in is the muscle layer, the third layer is the medulla layer, and the innermost layer is the nervous system.
Its secret to generating electricity lies in the third layer—the medulla. Inside the parasite's tube, there are a large number of electrocytes, similar to small stacked batteries. When stimulated by the host's nerve signals, they can cause electrical ions to pass through the cell membrane and accumulate.
The parasite contains these cells from head to tail, like many stacked batteries. When an electric current is generated, all these "batteries" are connected in series, creating a high voltage between the parasite's head and tail. Many of these battery packs are then connected in parallel, allowing a sufficiently large current to be generated outside the body.
In addition to this, this parasite, which can generate electricity, has an even more peculiar function—body regeneration.
When this parasite is cut in two with a sharp instrument, the muscle layer on the cut surface will immediately contract, and some of the muscle will quickly dissolve to form a new cluster of cells. At the same time, the cells will gather on the cut surface to form an embolism, causing the wound to close quickly.
Meanwhile, cells in the nervous system, medullary canals, and other tissues within the body can rapidly reproduce through budding via numerous mitotic divisions. Thus, as cells continue to proliferate, a new head will grow from the section lacking a head, and a tail will grow from the section lacking a tail. In this way, one parasite becomes two complete parasites.
Ultimately, Todd gave this parasite, which could generate electricity and regenerate, an eccentric name—"Tesla".
