Tadpoles' development inside the vocal sac of the male
Relies on camouflage to avoid predators, lying on the ground looking like a dead leaf

Reproduction 5
The female Darwin's frog lays up to forty eggs among the leaf litter. The male guards them for about three to four weeks until the developing embryos begin to move, and then he ingests the eggs and holds them in his vocal sac. They hatch about three days later and he continues to carry the tadpoles around in his vocal sac where they feed off their egg yolks and secretions produced by the wall of the sac until metamorphosis. At this stage, about 6 weeks after being swallowed(a duration in which the adult male eats nothing[8]), the small frogs hop out of the male's mouth and disperse.
