Amphibians possess diverse colour patterns and body markings that can be used to identify individuals, just like fingerprints for humans. This is how Naitik Patel and Dr Abhijit Das came up with one of the very first non-invasive techniques to identify individual frogs using a biometric software. Their protocol, recently published in the open-access journal Herpetozoa, allows for the rapid estimation of frog populations. Thus, it is meant to aid conservation of many endangered amphibians.
