Gjarpinjt e gjakut (also known as blood-sucking leeches) are little animals that live in water and like to suck on blood. They use their special mouths to attach to a person or animal's skin and then suck out blood like a straw.
People used to believe that having these leeches attached to their skin could heal them from illnesses, but now we have medicine to help us feel better. Some people still use leeches in certain medical treatments, but it's not very common.
If you ever see a gjarpinj e gjakut, it's best to stay away from it and not let it attach to you because it can hurt and make you bleed. If you get one on you, you can gently pull it off or seek help from a grown-up or doctor.
