Goliath Frog

The World’s largest frog is known as the Goliath frog or the giant slippery frog. The unusually big animal is endemic to Africa. It is found in Cameroon and Equatorial Guinea.

According to Wikipedia, the gigantic Goliath frog at the egg stage is about the same size with the tadpoles but grows bigger at the adult stage.

“Their eyes can be nearly 2.5 cm (1 in) in diameter. The conspicuous tympanum has a diameter of about 0.5 cm (0.20 in) and is separated from the eye by about 5 cm (2.0 in) in adults.”

Goliath frogs have fully webbed toes with the second toe being the longest. The frog is largely green colored but the abdomen and ventral part of the limbs are either yellow or orange. They have no vocal sacs or nuptial pads but possess a sharp sense of hearing.

While they serve as pets for some people, Goliath frogs are equally a food source.

The Equatorial Guinean government states that over 300 of the frogs may be exported out of the country. Consequently the animals have been considered a one of the endangered species in Africa.

Naturally opposed to confinements, the frogs reproduce more in their natural and free habitats.

In other words, capturing and exporting them out of their range contributes to their possible extinction.

On the other hand, it appears there is a longevity advantage to their captivity. The frogs live up to 21 years in captivity compared to the 15 years estimated range as they are preyed upon by snakes, Nile crocodiles, and other predators in the wild.

Bio-Expedition also gives another challenge with the conservation of the Goliath frogs.

“Due to habitat destruction the number of Goliath Frogs left in the wild continue to diminish. At this point in time they are considered to be endangered.”

The Goliath frog is usually found in areas where there are fast-flowing rivers with sandy bottoms.

“These rivers are usually clear and highly oxygenated. Their actual range spans from the last 200 km (120 mi) of the Sanaga basin in Cameroon to the north to the last 50 km (31 mi) 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.

Just like the chameleons, they have he camouflage qualities. A Goliath frog changes to the color of its immediate environment, that way they are able to capture their preys as well as escape their predators.
