endangered

Common Name: Goliath Frog
Scientific Name: Conraua goliath
Family: Conrauidae – the slippery frog family
Location: Cameroon and Equatorial Guinea
Size: 13 inches / 33.02 cm – Largest living frog species

The Goliath Frogs are found in fast-moving streams in Cameroon and Equatorial Guinea. The males have no vocal sacs to call to females, so they whistle. The males are actually bigger than the females, something uncommon in frogs. During the mating season, the male frogs fight over breeding territory. They also nests out of rocks in the fast-moving water. It is hypothesized that the males are larger because of this. The tadpoles only eat the plant Dicraeia warmingii, which could be why the frog has such a tiny range where they live.

Sadly, the Goliath Frog is listed as Endangered by the International Union for the Conservation of Nature (IUCN) redlist. They face challenges on two sides. Their habitat is being cut down to make room for plantations and houses. The frogs are also hunted for their food and for the pet trade.
