[2] The family Glossiphoniidae contains one of the world's largest species of leech, the giant Amazon leech , which can grow up to 45 cm in length. [ 12 ]
Leeches are hermaphrodites, and mating may take place on or off the fish host, but in either case, the cocoon, usually containing a single egg, is deposited elsewhere, usually stuck to a stone or piece of vegetation, or even to the carapace of a crustacean. When the egg hatches, the juvenile leech has about a week to find a suitable fish host ...

E. punctata is a hermaphrodite, and courtship involves two individuals stimulating each other by contact. The eggs are normally laid in May when the water temperature begins to rise.
These leeches have five pairs of eyes, with the last two separated by two eyeless segments. The family is monotypic , containing only the subfamily Haemadipsinae , though as the family can apparently be divided into two or three distinct lineages, at least one of the proposed splits , while not a distinct family, might be a valid subfamily.
