Goliath Frog – The World's Biggest Frog

Most frogs can fit in the palm of your hand, or even on the tip of your finger. But the Goliath frog (Conraua Goliath), the world’s largest frog, may grow up to 3 feet long when it is stretched out and can weigh as much as a newborn baby, about 7 lbs (3.2 kg).

The Goliath frog’s greenish brown color helps to hide it among wet moss-covered rocks in fast-flowing rivers in the dense coastal rain forest of Cameroon and Equatorial Guinea in western Africa. Unlike most other frogs and toads, Goliath frogs have no vocal sac and so courtship does not involve displaying any calls. They mainly eat crabs, but will also eat insects and smaller frogs. The Goliath frog can live up to 15 years.

Because Goliath frogs live in such a small area of the rain forest, they are highly vulnerable to habitat loss through logging and clearance of forest for agricultural land. The construction of dams threatens the breeding habitat of these frogs. The frogs have been heavily collected for zoos and the pet trade, but Goliath frogs don’t breed or survive well in captivity. Goliath are also highly prized as delicacy by local people.

The IUCN (The International Union for Conservation of Nature) sites Goliath frogs as an endangered species because of a 50% decline in population size in the last three generations.
