The African bullfrog (Pyxicephalus adspersus) is a species of frog in the family Pyxicephalidae. It is also known as the pixie frog due to its scientific name. It is found in Angola, Botswana, Kenya, Malawi, Mozambique, Namibia, South Africa, Swaziland, Tanzania, Zambia, Zimbabwe, and possibly the Democratic Republic of the Congo; it has been extirpated from Eswatini.[1] It has long been confused with the edible bullfrog (P. edulis) and species boundaries between them, including exact range limits, are not fully understood.[1][2] Additionally, P. angusticeps of coastal East Africa only was revalidated as a separate species in 2013.[2]
The natural habitats of the African bullfrog are dry savanna, moist savanna, subtropical or tropical dry shrubland, intermittent freshwater lakes, intermittent freshwater marshes, arable land, pastureland, canals, and ditches. It is among the largest frogs (third only to the goliath frog and the cane toad),[3] with males weighing up to 1.4 kg (3.1 lb). Females are half the size of males, which is unusual since in most amphibian species females are larger than males, to help the amplexus. Males can reach 24.5 cm (9.6 in) in snout–to–vent length, while females are much smaller.[4][5][6][7]
