Reproduction

In most species, the tadpoles are endotrophic (developing without external food sources) and develop in water housed in small hollows in the forest floor or holes at the end of flooded tunnels.^[2] Males call from inside burrows and may engage in duets with their nearest neighbours.^[3] They also show parental care: males remain by the clutch, and later on also by the tadpoles, in small aquatic microhabitats in the ground; this behaviour is associated with significant weight loss.^[4]
