Many people differentiate frogs and toads as separate species. While they do show slight characteristic differences, it may astonish you to know that they belong to the same order, Anura. This vital knowledge paves the way for us to explore the life of the Goliath frog, the world’s largest.

Aptly named, the Goliath frog hails from just two nations in the world: Cameroon and Equatorial Guinea in Africa. This titanic amphibian can astonish by stretching out to a length of over 30 inches – a mammoth compared to the other members in its family. And it’s not just about the length: the Goliath can tip the scales at over seven pounds!

  • Favorite Food: Mostly crabs.
  • Lifespan: Up to 15 years.
  • Special Abilities: Can leap over 10 feet in one jump!

Nature has bestowed upon the Goliath a fascinating paradox. Despite its size, it cannot croak or voice, yet possesses a remarkable sense of hearing. Unfortunately, the number of these intriguing creatures in the wild is decreasing at an alarming rate.

While not as enormous as its African cousin, the American bullfrog certainly holds its place in the world of giant amphibians.

American Bullfrog at a Glance

The American bullfrog generally grows up to six inches long. Some even make it to eight inches. With their legs fully stretched, they can measure up to 18 inches. Their varied diet includes land-based and water-borne insects, along with any animal they can overpower.

The American bullfrog thrives in the United States’ damp habitats, such as swamps or places near lakes and rivers. However, it definitely has a liking for warmer climates. You are most likely to spot them in the Midwest or Southern parts. In fact, the bullfrog’s presence is so remarkable that it’s the official amphibian of Iowa, Missouri, and Oklahoma.

Comparing the Giants

There’s no denying that both the Goliath frog and the American bullfrog are awe-inspiring in their own right. The takeaway? Head outdoors or visit your nearest zoo to encounter these fascinating creatures and get a firsthand view of their stunning sizes!
