Conraua goliath, also known as ‘goliath frog’ is the largest frog in the world, with some adult individuals weighing as much as 2.99 kilograms and measuring more than 33 centimetres (cm) in length, excluding their legs, when fully grown. And their eyes are about 2.5 cm wide, which is larger than the average eye size of humans.
- They are found only in the tropical rainforest of central Africa, within the south western part of Cameroon and north of Equatorial Guinea. Scientists believe the goliath frog has been around for over 250 million years.
- One of the most interesting behaviours of this species was discovered in a recent study, which revealed that they build nests for their eggs and tadpoles by moving rocks more than half of their body weight.
- This species has a limited geographic distribution, narrow ecological requirements and is largely hunted by the local communities in Cameroon and Equatorial Guinea for consumption and pet trade.
- Goliath frogs are exported to the US for participation in frog jumping contests. Climate change, deforestation, commercial agriculture, and over-hunting are some of the prime causes driving this species to extinction.
- As a result, the goliath frog has been classified as an ‘endangered species’ by IUCN and as a protected species of class ‘A’ according to wildlife law in Cameroon. According to a recent estimate, the total population of goliath frogs has dropped by at least 50 per cent over the last 15 years. They are on the brink of extinction, warn local amphibian conservationists.
