Frogs are an ancient, diverse and largely carnivorous group of amphibians whose origins date back to approximately 265 million years ago. They are widely distributed, ranging from the tropics to the subarctic regions, although the greatest concentration of frog species is found in the world's tropical rainforests.

However in the United Kingdom it is sometimes possible to come face to face with an African bullfrog - Pyxicephalus adspersus, a common pet which is often illegally released into the wild. Male African bullfrogs easily put our native frogs quite literally in the shade by exceeding weights of 2kg and with a body length of up to 23 cm.
However when it comes to being the world's largest frog the African bull frog is nothing more than small potatoes. The holder of that particular title is the magnificent Goliath frog - Conraua goliath.

Unfortunately the goliath frog is currently classified as an endangered species. On top of being preyed upon by snakes, Nile crocodiles, and Nile monitor lizards it is also considered to be a source of food in some parts of west Africa. Furthermore they are taken from the wild in large number for collectors, zoos and animal dealers to be sold as pets. Once in captivity they are not known to breed.
The largest frog ever to have lived!

Research on the fossilised skeletons of the Beelzebufo have shown that it sported a protective shield and powerful jaws. Scientists believe that it is likely that the Beelzebufo was both large enough and strong enough to have caught and fed on hatchling dinosaurs
