Seven New Species of Miniature Frogs Discovered

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.
Miniaturisation allows the frogs to emerge from their eggs as fully-formed, albeit tiny, adults.
