The African bullfrog (Pyxicephalus adspersus) is a species of frog in the Ranidae family. It is also known as the pixie frog due to its Latin name. It is found in Angola, Botswana, Kenya, Malawi, Mozambique, Namibia, South Africa, Swaziland, Tanzania, Zambia, Zimbabwe, and possibly Democratic Republic of the Congo.

Its natural habitats are dry savanna, moist savanna, subtropical or tropical dry shrubland, intermittent freshwater lakes, intermittent freshwater marshes, arable land, pastureland, and canals and ditches. This is a large frog, with males weighing 1.4 kg (3.1 lb), though can easily exceed 2 kg (4.4 lb); females are half the size, making it unique among frogs, as in most amphibians females are usually larger than males. Males can reach 10 inches while females only reach about 6 inches.[citation needed]

Feeding and habits[edit]

The African bullfrog is carnivorous and a voracious eater, eating insects, small rodents, reptiles, small birds and other amphibians.[citation needed] This frog is also aggressive and has been known to bite when provoked.[2] An African bullfrog kept at the Pretoria Zoo in South Africa once ate 17 baby cobras (Hemachatus haemachatus).[3] In a single-sex environment, the African bullfrog can switch genders. They emit a loud croaking and a bleating sound when stressed or handled. Like the Pacman frogs and the Budgett's Frogs, African Bullfrogs also bite when they are provoked. Its one of three frog species that have sharp teeth and bite humans when they are provoked or handled by humans (when they are getting picked up by humans using their hands to lift them up). The other two frog species are Pacman frogs and Budgett's Frogs because they also bite, just like the African Bullfrog does, even if they are not in the same frog family, or the same species.

In pet trade[edit]

The African bullfrog is an exotic pet in many countries around the world, and owning it is not prohibited by any laws. Animals sold are generally bred in captivity.

In popular culture[edit]

In the film Jurassic Park, dinosaurs are cloned for a theme park and are kept from breeding because each one is cloned to be a female. The genetic coding of the dinosaur DNA is completed with the DNA of a frog, and as a result, the dinosaurs change their gender in order to breed, just as a West African bullfrog would in a single-sex environment.
