Our new star in this line is the Darwin's Frog that is native to streams and forests of Chile and Argentina. It is possible this species is now extinct. It has not been seen since 1981. This tiny frog species (approx. 3.5 cm/1.4" in length) got its name after explorer Charles Darwin. He discovered the frog during his "Voyage of the Beagle". Darwin's Frog is able to camouflage itself on the forest floor, thanks to its evolving look like a dried-up leaf. The Northern Darwin's frog exhibits 'mouth brooding' parental care, whereby the young undergo part of their development in the father's mouth until the metamorphosis process is complete.
