predacious or parasitic annelid worm of the class Hirudinea, characterized by a cylindrical or slightly flattened body with suckers at either end for attaching to prey.
Leeches are annelids comprising the subclass Hirudinea. There are freshwater, terrestrial and marine leeches. Like earthworms, leeches are hermaphrodites.
Leeches are often misunderstood. Some species are true bloodsuckers that are capable of attacking humans, but these make up only a small proportion of the leeches. Most leeches feed on the soft tissues of their prey.
Leeches Types
Leeches are grouped according to the different ways they feed. One group (the jawed leeches or Gnatbobdellida) have jaws armed with teeth with which they bite the host.
