Darwin’s Frog are named after Charles Darwin who described them on his trip on the HMS Beagle. Darwin’s frog are mainly diurnal 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.
