Helobdella Nilae
''Helobdella'' is a genus of leeches in the family Glossiphoniidae, the freshwater jawless leeches. They occur worldwide.Kutschera, U., et al.

These are small, flat leeches which do not feed on blood.Siddall, M. E. and E. Borda.

Several species in this genus are used as model organisms in the study of developmental biology. It has been difficult to define species in this genus without DNA analysis. Like other leeches in this family, some ''Helobdella'' species are polymorphic, coming in different colors and patterns. On the other hand, some uniformly ...

Helobdella Stagnalis
''Helobdella stagnalis'' is a species of ''Helobdella''. The species was described in 1758 by Carolus Linnaeus Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the ... as ''Hirudo stagnalis''. It has cosmopolitan distribution.

Helobdella Robusta
''Helobdella robusta'' is a leech of the family ''Glossiphoniidae''. Its genome has been sequenced by the Joint Genome Institute The U.S. Department of Energy (DOE) Joint Genome Institute (JGI), first located in Walnut Creek then Berkeley, California, was created in 1997 to unite the expertise and resources in genome mapping, DNA sequencing, technology development, and ..., and its early development has been studied extensively. ''Helobdella'' leeches called "''H. robusta''" in literature may not all be from the same species, though they are closely related. At least two species originally termed ''H. robusta'' are present at the same locality, the Sacramento River at the Sacramento Fairgrounds. Another closely related leech is now called ''Helobdella sp. (Austin)''.Kuo, D and Weisblat, DA (2011). "Intermediate filament genes as differentiation markers in the leech Helobdella".
