African Bullfrog

Pyxicephalus adspersus

A Big Leap

The African bullfrog is one of the largest species of frog, often weighing several pounds. They are burrowers, spending most of their lives underground to escape the harsh conditions of the climate they live in.

About the Species

During dry seasons, African bullfrogs go through a process called aestivation.

Aestivation is a time similar to hibernation; but instead of being onset by winter, aestivation happens during times of extreme drought and heat. The African bullfrog will burrow down to avoid high temperatures, reducing its breathing and metabolism to almost nothing in order to save energy. African bullfrogs can stay in this state for many months, and only emerge during the short rainy season to mate. Mating is quite the ordeal, with males battling for females. Males actually take care of the young tadpoles once they hatch! Because of their large size, this species is commonly targeted by locals for a food source.
