Giant Slippery Frog

• GeneralIt is the largest frog in the world, with a body of up to 32 cm and a weight of up to 3.3 kg; it builds nests by moving stones.
• récordIt is the largest frog in the world, able to top 3 kilograms, and curiously has no vocal sac, so it does not croak.
• It builds ponds: in 2019 it was documented that the adults shift stones weighing several kilos and clear the gravel of the riverbed to dig breeding pools where the tadpoles are safe from the current and from predators. It is one of the few known amphibian builders.
• It is the largest frog in the world: with its legs extended it is more than eighty centimetres long and weighs more than a small cat.
• It does not croak: it has no vocal sac and communicates with whistles made with its mouth open, which is remarkable in a frog of its size.
