Several behaviors, some of which are stereotyped and largely invariable, but most of which are context-dependent, were discovered. Males emit loud, double-note advertisement calls from elevated perches in their territories. When a female approaches a calling male, his vocalizations drop in volume as he approaches her, and he places his throat on the top of the female's head or dorsum. The male then leads the female to a potential oviposition site. Females often reject oviposition sites, at which point the stereotyped chinning and leading behavior resumes.
Successful courtships result in a single egg being laid above the water line.
This is the lowest known clutch size for an anuran without direct development, and is suggestive of a high degree of parental care. Tadpoles cannibalize conspecific eggs. Their most common source of food is fertilized eggs, which are the result of courtships. Facultative maternal care occurs when mothers return, alone, to the wells they mated in, and deposit a single, unfertilized egg for their tadpole to eat. Males and females have distinct interests during courtship and reproduction.
