The world’s largest frog species is very aptly named – the goliath frog, also known as the giant slippery frog and goliath bullfrog. Native to Equatorial Guinea and Cameroon, it can grow up to 32cm in length and weigh up to 3.25kg.

Despite its remarkable size, it doesn’t begin with a head start over other frog species. Instead, its tadpoles are the same size as an average frog tadpole.

During a recent survey by the Bristol Zoological Society and INDEFOR-AP, the national park service of Equatorial Guinea, the species was seen in Equatorial Guinea for the first time in almost two decades.

“When the team came out of the forest they were overjoyed to share the news. This incredible frog hasn’t been officially confirmed in the national park by INDEFOR-AP for almost two decades,” said Dr Gráinne McCabe, Head of Field Conservation and Science at Bristol Zoological Society.

“However, it was only seen in one small section of the survey area, indicating it needs to be better protected. Now that we know the species has not disappeared, we can study the amphibian in more detail, monitor its presence and help protect this endangered species.”
