The world's largest frogs?

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). This animal has a relatively small habitat range, mainly in West Africa (near Gabon). Its numbers are dwindling due to habitat destruction and collection for the pet trade.

The goliath frog can live up to 15 years. Goliath frogs 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.

Not much is known about the goliath frog's reproduction; however, some African scholars have started to do more research for medical reasons.

Goliath frogs were considered to be a source of food in some parts of west Africa. They were also highly exported to zoos and animal dealers to be sold as pets. Unfortunately, these frogs fail to thrive in captivity (and almost never reproduce there). Due to their classification as endangered, the Equatorial Guinean government has declared that no more than 300 goliaths may be exported out of the country per year. Fortunately for the frogs, even the most experienced of animal collectors can usually find no more than a dozen per trip.
