Planaria is an animal rarely visible in biological pools, even if there were many there. But it is a species widely used in scientific biology laboratories. This species can be cut into pieces, and each piece can regenerate into a complete organism! What sounds brutal has greatly helped scientists to better understand the biology and function of cells. In general, Planaria is a very famous “model organism”, which is why it is used in many laboratories around the world to investigate the function of genes and other fundamental processes for any living being.

Therefore, finding a wild Planaria in the biological pool should always be a reason to think about how other organisms that are little appreciated by us, and even worms like Planaria, are helping humanity to learn more about the extraordinary life on our planet.
