The biggest kind of frog is the Goliath frog (Conraua goliath).
They come from Cameroon in West Africa. Their bodies can reach the
size of nearly a foot (30 cm) long. The Conraua Goliath weighs as
much as a large housecat, about 3.3 kilos! Not to be confused with
the Goliath Tree Frog. The Goliath tree frog is the largest of the
tree frogs. They get to be a little bigger than golfball size. They
are cousins of the viatnamese tree frog.
