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. There are also lots of leech species that don't suck blood. They are predators, eating worms, snails, aquatic insects, and other invertebrates.
