Seven new species of miniature frog, smaller than bumblebees, have been discovered clinging to survival on isolated mountaintops in Brazil.

The largest of the new discoveries has a maximum adult length of just 13mm. The frogs, which are among the smallest land vertebrates, have evolved with fewer fingers and toes in order to reduce their size.
