How to African bullfrogs reproduce?

African bullfrogs breed during the rainy season. Males produce deep calls to attract potential mates. They gather in small ponds in large groups called leks with the biggest, most dominant frogs positioned in the center. Competition can be intense, and it is not uncommon for males to come to blows. These fights can result in serious injury and even death. Females lay up to 4000 eggs at a time, which the males fertilizes in the water. Like frog species they are sexually dimorphic, but it is the male that is the larger whereas in both other species it is the female. Once the female has laid her eggs, the male watches over them. He will continue to look after them even once the tadpoles have hatched, aggressively driving off perceived threats and even helping to relocate them if their pool is in danger of drying out.

With proper care, an African bullfrog can live 30 years or longer.
