Arhynchobdellida

The Arhynchobdellida are an order of leeches that are characterized by the absence of a protrusible pharynx. This order includes leeches with three toothed jaws or no jaws at all, and they are typically found in terrestrial or freshwater environments. These leeches can be bloodsuckers or carnivorous. Leeches, in general, are segmented worms belonging to the subclass Hirudinea. They possess suckers at both ends of their bodies and have a fixed number of 34 body segments. Leeches are hermaphroditic, meaning each individual has both male and female reproductive organs, but they require cross-fertilization.12
