DNA barcoding is a new method for biological taxonomy, offering the ability to identify species from fragments in any life-history stage. Pleuronichthys cornutus and P. japonicus are two morphologically similar species. Pleuronichthys japonicus has never been found previously in China. However, in this study, we identified both species using DNA barcoding (cytochrome c oxidase subunit I (COI)), the mtDNA control region and cytochrome b. The results reveal that: 1) intraspecific variation in the DNA barcode ...
