The Glossiphoniidae, the freshwater jawless leeches, [citation needed] or leaf leeches (due to their shape) [11] are freshwater leeches, flattened, and with a poorly defined anterior sucker. [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 ]
Glossiphoniidae are a family of freshwater proboscis-bearing leeches. These leeches are generally flattened, and have a poorly defined anterior sucker . Most suck the blood of freshwater vertebrates like amphibians , crocodilians and aquatic turtles , but some feed on invertebrates like oligochaetes and freshwater snails instead.
Arhynchobdellida, the proboscisless leeches, are a monophyletic order of leeches. They are defined by the lack of the protrusible proboscis that defines their sister taxon, the Rhynchobdellida . [ 1 ] [ 2 ] [ 3 ] Arhynchobdellida is a diverse order, compromising both aquatic and terrestrial , besides sanguivorous and predatory , leeches. [ 3 ]

"The medicinal leech is one of our most threatened freshwater species. It’s also very misunderstood,” said ecologist Dr Naomi Ewald, from the Freshwater Habitats Trust, a conservation charity ...
The majority of freshwater leeches are found in the shallow, vegetated areas on the edges of ponds, lakes and slow-moving streams; very few species tolerate fast-flowing water. In their preferred habitats, they may occur in very high densities; in a favourable environment with water high in organic pollutants, over 10,000 individuals were ...
At other times, it is free-living in freshwater habitats. The adult broods its egg capsules on its under surface, where there may be as many as two hundred eggs. [2] When the young are ready to emerge, the adult uses its sensilla organs to detect vibrations in the water and will move towards any disturbance that might be caused by a potential ...
