Morphological and genetic variations of the freshwater leech, Hirudinaria spp., in Peninsular Malaysia
In this study the genetic diversity of local freshwater leeches (Hirudinaria spp.) was inferred using mtDNA COI gene analysis and compared with the gross external variations of 26 freshwater leech specimens obtained from the wild and leech farms. Based on a neighbor-joining tree generated from 516 C...
