La explicación científica detrás del misterio de los sapos que explotaron en Alemania

In the spring of 2005, thousands of common toads (Bufo bufo) in Germany died after swelling up and exploding, baffling the scientific community. The mysterious phenomenon has since been explained by researchers, who identified the cause as the adaptive intelligence of crows.

According to the scientific findings, crows learned to exploit a vulnerability in the toads as a defensive mechanism. By pecking precisely at the toads' skin to extract their livers, the crows induced a fatal stress response that caused the amphibians to inflate and rupture.
