The Darwin’s Frog are named after the father of evolution, Charles Darwin, who described them on his trip on the HMS Beagle. Darwin’s frog are mainly diurnal (active during the day) but males call during the night. Once the female frog lays the eggs, the male guards them until the embryos start to move. Then the male swallows the embryos and puts them in his vocal sac until they undergo metamorphosis, at which point they jump out of its mouth.


The frog is endanger of becoming extinct. The forests were they live are being transformed into plantations. Also, chytrid fungus is another factor in the decline of the Darwin’s Frog.
