The genus is unique because it contains the only two known frog species that incubated the prejuvenile stages of their offspring in the stomach of the mother. [ 3 ] The combined ranges of the gastric-brooding frogs comprised less than 2,000 square kilometres (770 sq mi).
The frog Allobates zaparo is not poisonous, but mimics the appearance of other toxic species in its locality, a strategy that may deceive predators. [165] Many amphibians are nocturnal and hide during the day, thereby avoiding diurnal predators that hunt by sight. Other amphibians use camouflage to avoid being detected. They have various ...
The skin fragments that were found in their stomach are an indication that these frogs commit cannibalism or eat their own skin which is common among amphibians. Based on these results, P. pipa is an ambush predator that will opportunistically eat anything that falls into the water or that it may encounter when occasionally foraging on land.

Unlike other frogs, they have no tongue to extend to catch food, so clawed frogs use their hands to grab food and shovel it into their mouths. [13] These frogs are particularly cannibalistic; the stomach contents of feral clawed frogs in California have revealed large amounts of the frog's larvae. [14]
