What is the typical maximum length of a Goliath frog?

The typical maximum length of a Goliath frog is 32 centimeters. This measurement refers to snout-to-vent length, running from the tip of the frog’s snout to the opening at the rear of its body.

The Goliath frog, Conraua goliath, is the largest living frog species. It inhabits fast-flowing rivers and waterfalls in parts of Cameroon and Equatorial Guinea, where its powerful hind legs help it move through rocky, turbulent habitats. Despite its size, it has a frog’s familiar body plan and does not possess unusual structures such as claws or a tail.

Large individuals can weigh more than 3 kilograms, making this species strikingly heavy as well as long. Its size often causes confusion with the world’s largest amphibians overall: that title concerns giant salamanders, not frogs. The African bullfrog is also enormous and heavier-looking, but it is shorter than a full-grown Goliath frog.

Goliath frogs are threatened by habitat loss, hunting, and collection for the international pet trade. Their dependence on clean, rapidly flowing water makes river alteration especially damaging.
