Researchers found the dead nose-horned female viper with its prey exploding from its side during a field study in Macedonia on May 14 last year. Both creatures were dead.
Researchers believe that the 20cm young snake may have underestimated the size of the prey and paid a fatal price.
The reptile was found on Golem Grad, also known as Snake Island, and was reported in the journal Ecologica Montenegrina by Serbian herpetologist Ljiljana Tomovic last month. More photos below:
