Echidnas reproduce through internal fertilization. Males use their spiny penis, which has four shafts, to fertilize the female's eggs during mating. After fertilization, the female lays one or two eggs, which she incubates in a pouch until they hatch. The young echidnas, called puggles, remain in the pouch for several weeks before emerging to continue their development.
