Leeches are famous as blood-suckers. The species that feed on blood have special chemicals in their saliva that prevents blood-clotting. Many blood-feeding leeches attack only fish, a few attack any vertebrate (including people), and a few are specialists on another group of animals, like turtles or waterbirds.
