African Pixie Frog Facts: Size, Looks and Habits

The African pixie frog is a pet-trade name for the African bullfrog, Pyxicephalus adspersus. Despite the cute name it is not small. Males reach about 9 to 10 inches and over 2 kg, while females are much smaller. It is olive green with bumpy skin, lives in open grassland in Africa, spends much of the year underground and eats almost anything it can fit in its mouth.

Many pet shops call the African bullfrog a pixie frog. The name suggests a tiny frog, but adults are among the largest frogs in Africa.

This guide explains the name, and it covers size, looks, range, diet and behaviour from zoo, university and frog-atlas sources.

What is the African pixie frog?

The FROGLAND pet-frog FAQ says the African bullfrog is often called a pixie frog because of its Latin name, Pyxicephalus. It also says P. edulis is sometimes called pixie, and that the two are often confused.

Scientists prefer the full name, so we use Pyxicephalus adspersus here. Our guide to dwarf African bullfrog facts covers the smaller species.

How big does it get?

The Oregon Zoo says males reach about 9 inches and females about 4 inches. Lafeber Veterinary says males reach 20 to 25 cm and often weigh over 2 kg. FROGLAND gives up to 9.5 inches (24 cm) and a female of about 12 cm.

The South African frog atlas (BDI) reports Gauteng males reaching 245 mm and 1.4 kg. Males are always the larger sex. Sizes vary by region, since frogs in the Eastern Cape and Free State seldom exceed 140 mm.

Appearance

FROGLAND describes olive green, bumpy skin, with a yellow throat on males and a cream throat on females. Only the hind toes are webbed.

The Oregon Zoo notes short, blunt fingers without webbing. Animal Diversity Web says the lower jaw carries three large tooth-like odontodes.

Where it lives

FROGLAND says it favours open grassland and ranges from Nigeria east and south through the savanna regions. The Virginia Zoo lists savannas, shrublands and tropical swamps of central and southern Africa.

BDI says it is widely distributed across southern Africa, including central Namibia, Botswana and the Zimbabwean highveld.

Diet and behaviour

It is an ambush predator. FROGLAND lists large insects, fish, mice, lizards and other frogs. BDI adds birds, snakes, scorpions and crabs, and notes cannibalism.

Adults dig burrows 0.5 to 1 m deep and form a skin cocoon in dry spells, says BDI. FROGLAND says the frog can inflate its body when frightened and that males can bite.

Pixie frogs as pets

Lafeber says one adult can live in a 20 gallon long terrarium, at 25 to 28 C (77 to 82 F), and that adults should be housed separately. VetVerified gives a lifespan of 20 to 30 years.
