Species: Goliath frog (Conraua goliath)

Status: Endangered (EN)

Interesting Fact: The goliath frog is the largest frog in the world, weighing in at over 3 kilograms.

The goliath frog can be found in flowing rainforest rivers in Equatorial Guinea and Cameroon. Goliath frogs lack vocal sacs, and so their courtship displays do not involve the characteristic calls of most other frogs and toads. Females lay several hundred eggs onto vegetation on the river bottom, and once hatched, the tadpoles feed on the plant Dicraea warmingii. Complete metamorphosis takes around 85-95 days, and once mature the adults feed on insects, crustaceans and fish.

This species has a highly restricted range, as much of the dense rainforest of the goliath frog’s habitat has been deforested for timber or to make way for agriculture. Goliath frogs are also considered a delicacy and are collected by local people for food. Captive breeding programmes have not proven successful and the only method of effectively preserving this amphibious giant is to safeguard areas of remaining habitat
