Calling
Males start the courting process with a series of calls, using specialized vocal sacs. These calls not only attract potential female mates but also serve as a warning to other males, marking their territory.
Dance of Persuasion
Once a female approaches, the male puts on a display, hopping around her in a sort of dance to further entice her.
Breeding Sites
If the female is impressed, she follows the male to a suitable breeding site, often a damp, sheltered spot. This could be under leaf litter, inside bromeliads, or other suitable locations.
Egg Laying
After mating, the female lays a clutch of eggs, usually ranging between 3 to 5. The male then guards these eggs, ensuring they remain moist and safe from predators.
Development From Egg to Tadpole to Adult Frog
Egg Stage
This phase lasts for about 10-14 days. The male’s role is crucial here, as he keeps the eggs hydrated by transporting water using his back.
Tadpole Stage
Once the eggs hatch, an even more fascinating behavior emerges. The mother transports each tadpole, one by one, on her back to individual water-filled locations, often inside bromeliads.
Here, the tadpoles will develop for the next 6-8 weeks. To nourish them, the female lays unfertilized eggs in each tadpole’s water source, providing them with essential nutrients.
