Slug´s Body Grows Again – level 2

18-03-2021 07:00

Japanese scientists studied sea slugs, and they did it for many years. Recently, they discovered something unusual.

Scientists studied more than 80 slugs, and they saw that three slugs cut their heads off their bodies. Scientists thought that the slugs would die, but they moved and ate as usual. After a few days, their bodies started to grow from their heads again. It seemed that it was a way to remove parasites.

Scientists think that there are stem cells on the slug´s head. It is a very exciting discovery which could help in regenerative medicine. Regenerative medicine is when scientists look for ways on how to repair injured body parts or organs.

Difficult words: slug (an animal which looks like a snail without a shell), parasite (an animal or plant which lives on or inside a larger animal or plant and gets its food from it), stem cells (the smallest parts of a body from which any body part can grow), organ (a body part inside the body).
