African Bullfrog

Scientific Name Pyxicephalus adspersus

Native To Sub-Saharan Africa

Natural History

During times of drought, African bullfrogs can burrow underneath the ground and stay there for more than a year. They slough-off several layers of skin to form a tough cocoon. While underground their bodily functions slow down—a process known as estivation.

Least Concern

Conservation Status

Listed as “Least Concern” by the International Union for Conservation of Nature (IUCN). While these frogs are losing breeding habitat to urbanization, they are very adaptable and can live in a large variety of habitats.

Interesting Facts

  • A female bullfrog will lay up to 4,000 eggs in a single clutch.
  • The male bullfrog protects the eggs after they are laid, and even after they hatch into tadpoles. He will even dig channels in the mud to allow the tadpoles to swim into deeper water.
  • Bullfrogs get their name from the roaring croak sound that males make to attract females; the sound is similar to that of a bull.
