The tadpoles feed on algae , protozoa , rotifers , very small crustaceans , nematodes , detritus and fungal hyphae .

Danger

The IUCN lists Ololygon angrestis as “ Least Concern ” as Scinax angrensis , although its estimated potential distribution is only 5000 km² and the population trend is declining. The editors justify the classification by stating that the species is still common and that its habitat is not acutely endangered at the moment. In addition, Ololygon angrensis occurs in some protected areas. Deforestation mainly endangers the species.
