WORLDKINGS - Worldkings News - Africa Records Institute (AFRI) – Conraua goliath: Largest frog species in the world


( Specimens can grow up to 32 centimetres in length from snout to vent, and weigh up to 3.25 kilograms.

The goliath frog otherwise known as goliath bullfrog or giant slippery frog (Conraua goliath) is the largest living frog. Specimens can grow up to 32 centimetres in length from snout to vent, and weigh up to 3.25 kilograms. This species has a relatively small habitat range in Cameroon and Equatorial Guinea. Its numbers are dwindling due to habitat destruction and its collection for food and the pet trade.

The sexes of the goliath frog are similar. In a sample of 15 individuals, weights ranged between 600 and 3,250 g, and snout-vent lengths were between 17 and 32 cm.  Their eyes can be nearly 2.5 cm in diameter. The conspicuous tympanum has a diameter around 0.5 cm and is separated from the eye by about 5 cm in adults. Goliath frog eggs and tadpoles are about the same size as other frogs despite their very large adult form.

The goliath frog is normally found in and near fast-flowing rivers with sandy bottoms in the Middle African countries of Cameroon and Equatorial Guinea. These rivers are usually clear and highly oxygenated. Their actual range spans from the last 200 km of the Sanaga basin in Cameroon to the north to the last 50 km of the Benito River basin in Equatorial Guinea to the south. The river systems in which these frogs live are often found in dense, extremely humid areas with relatively high temperatures.

Although generally staying in the rivers during the day, they often emerge on land during the night. The goliath frog can live up to 15 years in the wild. In captivity, they can live up to 21 years. It is preyed upon by snakes, Nile crocodiles, Nile monitors, and humans, among other predators.
