Two-headed salamander tadpole discovered

8 diciembre 2014

Researchers have found a salamander tadpole which has two heads. Researchers noted that while they had observed an incidence of deformity, especially among the limbs of salamanders, in the past such cases of two heads were more rare. The reason for this deformity is unknown, but the chief theories are pollution of water sources, changes in radiation and the influence of a small population.
