African Bullfrog

Fascinating facts about the African Bullfrog

• Male African bullfrogs are exceptionally large, reaching up to 1.4 kg in weight and measuring 24.5 cm from snout to vent. In contrast, females are roughly half that size, a rare reversal of the typical amphibian pattern where females are larger to aid amplexus, and males dominate breeding arenas.
• The African bullfrog is a voracious carnivore that will consume any animal it can swallow, from insects and small rodents to reptiles, birds, fish and other amphibians. Its appetite is so extreme that a specimen at Pretoria Zoo famously swallowed 17 juvenile Rinkhals snakes in a single feeding. Juvenile bullfrogs also practice cannibalism, sometimes eating the tadpoles they guard.
• During dry periods the African bullfrog enters dormancy and constructs a cocoon that envelops its whole body, leaving only the external nostrils exposed. This cocoon dramatically reduces evaporative water loss, allowing the frog to survive prolonged aridity. When rain returns, the moisture softens the cocoon, enabling the animal to break free and resume activity.
• When the shallow breeding pool begins to evaporate, the male African bullfrog springs into action, using both his powerful legs and his head to carve a narrow channel that links the drying water to a deeper, permanent pond. This emergency canal keeps the water level sufficient for the developing tadpoles, which normally complete metamorphosis in about three weeks.
• The African bullfrog ranks as the sixth-largest frog on Earth, surpassed only by five other species. It shares this lofty position with the goliath frog, helmeted water toad, Lake Junin frog, Blyth's river frog and the cane toad, making it one of the most massive anurans known.
