African Bullfrog
Scientific name: Pyxicephalus adspersus
Large, very robust frog with voracious appetite, native to savannas and semi-arid zones.
Quick facts
- Approximate size15–25 cm
- Average weight0.5–2 kg
- Life expectancy20–40 years
- ActivitySeasonal
Basic information
- Home: savannas, grasslands and semi-desert areas with seasonal ponds in southern Africa.
- Food: large insects, other amphibians, small vertebrates and virtually any prey that fits in its mouth.
- Sexual dimorphism: males are much larger and more massive than females.
- Predators: large birds, mammals and humans; tadpoles and juveniles are prey to many aquatic animals.

Species overview
The African bullfrog is one of the largest anurans, adapted to cycles of intense rainfall and long droughts.
Natural habitat
Takes advantage of temporary ponds in grasslands and savannas; the rest of the year it remains buried underground in dormancy.
Behavior
During rains it emerges, feeds intensively and reproduces; then returns to burrow when water disappears.
Special traits
Its ability to encase itself in a hardened skin capsule allows it to survive long periods without water.
Conservation and threats
Some populations are relatively stable, but habitat transformation and capture can affect them locally.
Curiosities
Striking details about this species that help better understand its biology and role in ecosystems.
- Can enter estivation by burying itself during long drought periods.
- Males defend breeding ponds and may care for tadpoles by guiding them to areas with more water.
- Has very strong jaws capable of inflicting painful bites.
- Popular in terraristics, but its size and strength require responsibility.
Welfare profile
Summary of the most critical points if this species is kept in captivity at specialized centers.
Facilities and space
High
In captivity needs spacious terrariums with deep substrate and access to a safe aquatic area.
Water, light and microclimate
Medium
Feeding must be controlled to avoid obesity, common in captive specimens.
Handling and stress
Very delicate
Handling should be cautious due to its strength and size; not an animal to handle frequently.
African Bullfrog in captivity
General information intended for professional facilities and educational projects. Not intended to encourage capture or improvised keeping of wild amphibians.
⚠️ Amphibians are particularly vulnerable to pollution, emerging diseases and improper handling. Before keeping species like this, it is essential to review local regulations and seek qualified advice.
Suitable facilities
Only recommended for very informed keepers with sufficient space.
Feeding in responsible centers
- Enclosures should facilitate digging and hiding behaviors, plus an easily cleaned water area.
- Large prey such as mice, fish and other amphibians.
- Strict portion control.
Handling and welfare
It is essential to avoid releasing them in places where they are not native to prevent ecological impacts.
Ethical message
Their presence in educational collections can illustrate extreme adaptations to climates with seasonal rainfall.
This section has an educational purpose. Amphibian conservation involves, above all, protecting ponds, rivers, forests and wetlands, and avoiding irresponsible release of exotic species.
