Breeding takes place when there is a drop in water temperature and levels rise. Males attract females by making clicking sounds underwater; once there the male grasps the female and both swim about in somersaulting motions.

While in the males grasp, the female lays her eggs on the male's belly with a long oviduct, which is then fertilized.  The male then places the eggs on the female's back, where they adhere to her dorsal skin; the skin swells around the eggs within 24 hours, and fully-encloses them within 10 days.  The young develop in this manner until they hatch within 12 to 20 weeks, emerging from her skin as fully-formed toads.<ref>http://www.youtube.com/watch?v=aCayq56wHSA</ref>
