In this place we saw the flying leech, which they call zūlū (with u after the z and the l). It lives on the trees and grasses near water, and when a person comes near it, it leaps on him, and wherever it lands on his body a great deal of blood flows out! People keep lemons ready for it and squeeze them over it, so that it drops off them, and they scrape the spot where it landed with a wooden knife kept for that purpose.
