Goliath frog

A frog that is so big that it makes its own ponds using heavy rocks

It holds the esteemed title of being the largest frog in the world, renowned for its impressive size and remarkable behaviors. Found in the fast-flowing streams and rivers of Central and West Africa, these colossal amphibians display fascinating adaptations that contribute to their unique ecological niche.

One of the most extraordinary behaviors exhibited by Goliath frogs is their ability to move rocks weighing up to two kilograms to construct nests in streams. This remarkable feat of strength and ingenuity is considered essential for their reproductive success, as the sturdy nests provide a safe environment for their offspring to develop. The enormous bodies of Goliath frogs have likely evolved due to this hefty hauling, enabling them to carry out this vital aspect of their reproductive behavior.

Despite starting out as tiny tadpoles similar in size to those of other frog species, Goliath frog tadpoles exhibit an exceptional growth trajectory—they just keep growing. This rapid growth allows them to reach their impressive adult size, making them the giants of the frog world.

In addition to their formidable size, Goliath frogs possess a voracious appetite and will consume a wide variety of prey, including small mammals, insects, crabs, fish, and even other frogs. Unfortunately, their large size and popularity as a delicacy in the African bushmeat trade have made them targets for hunting and poaching.
