DNA testing reveals mislabeled frogs and salamanders sold online

AI Insight

Researchers used DNA barcoding to analyze amphibians sold in online marketplaces and discovered widespread mislabeling of species. Frogs marketed as Chinese edible frogs (Hoplobatrachus chinensis), a commonly farmed species, were actually Chinese spiny frogs (Quasipaa spinosa), which are classified as Vulnerable by the IUCN. The study, published in Nature Conservation, reveals that threatened amphibian species are entering the commercial trade either through deliberate fraud or accidental misidentification.


This finding exposes a significant loophole in wildlife trade regulation, where endangered species can be sold legally under the guise of common species. The discovery highlights the need for genetic verification in online wildlife markets to prevent the exploitation of threatened amphibians and ensure enforcement of conservation regulations.

A new study published in the journal Nature Conservation reveals that threatened amphibian species are being inadvertently or illegally sold under incorrect names in digital marketplaces. Using DNA barcoding, researchers discovered that frogs traded online as a widely farmed species, the Chinese edible frogs (Hoplobatrachus chinensis), were actually Chinese spiny frogs (Quasipaa spinosa), a species classified as Vulnerable by the IUCN.
