They are in the [[Ranidae]] [[family (biology)|family]]. They are [[common name|commonly named]] '''pixie frog''' because of their Latin name. They are found in [[Angola]], [[Botswana]], [[Kenya]], [[Malawi]], [[Mozambique]], [[Namibia]], [[South Africa]], [[Eswatini]], [[Tanzania]], [[Zambia]], [[Zimbabwe]], and possibly [[Democratic Republic of the Congo]]. They live in dry [[savanna]]s, [[subtropical]] or [[tropical]] [[habitat]]s. Males are bigger and longer than females. '''Growth Divergence:''' Sexual size differences were studied in the African bullfrog (''Pyxicephalus adspersus''), a species in which adult males are about 2.5 times larger than females. The growth profile shows that males and females begin to differentiate in growth at 4 weeks after metamorphosis, at the same time as the appearance of differentiated gonads.<ref>{{Cite journal|last1=Hayes|first1=Tyrone|last2=Licht|first2=Paul|date=November 1992|title=Gonadal involvement in sexual size dimorphism in the African bullfrog ( Pyxicephalus adspersus )|url=https://onlinelibrary.wiley.com/doi/10.1002/jez.1402640203|journal=Journal of Experimental Zoology|language=en|volume=264|issue=2|pages=130–135|doi=10.1002/jez.1402640203|issn=0022-104X}}</ref> '''Parental Care:''' The African frog (''Pyxicephalus adspersus'') expresses its parental care by scraping tadpole passages to larger water bodies. This gives cooler conditions for their young to survive in frequent overheating and rapid drying breeding pits.<ref>{{Cite journal|last1=Cook|firs
