TED-Ed: Want to know if you're pregnant? Use this frog | Carly Anne York

The African clawed frog has been a significant subject in scientific research due to its unique features and adaptability. Initially used in pregnancy tests, these frogs provided a reliable method for detecting HCG without harming the animals.

However, their introduction to non-native environments led to ecological issues, as they became invasive species and carriers of a deadly fungus. Despite their contributions to science, the ethical and environmental concerns surrounding their use remain significant.
