Orobdella is a genus of leeches. It is the only genus in the monotypic family Orobdellidae.[1][2][3] They are large annelids, with the largest species (Orobdella octonaria) exceeding 20 cm (7.9 in) in length, but some are much smaller: mature individuals of Orobdella koikei can measure only 4 cm (1.6 in). They inhabit the banks of mountain streams and feed on earthworms.[2][3] The majority of species are endemic to Japan; two species are known from Taiwan, one from Korea, and one from Russian Far East.[4]
