Goliath Frog: The world's largest frog

The goliath frog can grow up to 13 inches (33 cm) in length from snout to vent, and weighs up to 8 lb (3 kg). The goliath frog can be as big as some house cats! It doesn't start out so big, though. The tadpole of the goliath frog is the same size as the tadpole of an average frog but just keeps growing. The adult looks a lot like other frogs as well, just a whole lot bigger. They can live up to 15 years. They eat scorpions, insects and smaller frogs. These frogs have acute hearing but no vocal sac.

The goliath frog is normally found in fast-flowing rivers with sandy bottoms in the West African countries of Cameroon and Equatorial Guinea. These rivers are usually clear and highly oxygenated. Their actual range spans from the last 125 miles (200 km) of the Sanaga basin in Cameroon to the north to the last 30 miles (50 km) of the Benito River basin in Equatorial Guinea to the south. The river systems in which these frogs live are often found in dense, extremely humid areas with relatively high temperatures.
