[6] In total length, including outstretched legs, the largest specimens can slightly exceed 80 cm (31 in).

[5] The heaviest verified specimen, caught in the Muni River system in 1960, weighed 3,305 g (7.3 lb) and had a snout–vent length of 34.0 cm (13.4 in).

This species is primarily located in a dense equatorial forest fringe which is somewhat parallel to the coast and surrounded by rivers.

These distribution patterns emphasize its limited environment which tends to have a clear preference for water territories.

[9] The primary threat to the goliath frog is hunting, as it is considered a food source in its native range.

[1] The IUCN has highlighted the need for conservation measures, in cooperation with local communities, to ensure hunting occurs at sustainable levels.

Frogs weighing less than 400 g (14 oz) consumed annelids, arachnids, myriapods, insects, crustaceans, gastropods, and reptiles.

[14] Goliath frogs have been observed to create three main nest types, all semi-circular in shape and located in or near a river.

The third is constructed by digging a new pool roughly 1 m (3 ft) wide and 10 cm (4 in) deep, sometimes moving quite large stones in the process.

[15] While the reproductive behavior for this species is mostly not well-known, studies by Lamotte, Perret, and Zahl have allowed an overall chronological table of larval development to be created.

[6] First Month: no organs were differentiated and only the ocular region showed significant pigmentation and transparent external gills.

As the month continues, pigmentation is becoming more intense via the presence of nearly black spots, two rows of teeth are developing on both the upper and lower lip, feeding increases greatly, and their size becomes 24 mm (0.94 in).

Finally, at the end of the month, anterior legs have fully appeared, posterior legs are grown with long and powerful fingers accompanying this growth, the mouth has become an arched slot line, tail regression has begun, and these tadpoles begin to put their head out of the water in order to breathe.

The tail has been either completely or nearly reabsorbed, the shape and color of adults is obtained with slightly lighter and greener pigmentation, the total length is 35 mm (1.4 in).

[14] Typically, the goliath frog attaches its eggs either underwater, in small groups to rocks, or in gravel or larger pieces of wood.

Additionally, these nests allow the Goliath frogs to become less dependent on existing structures for egg deposition which can allow these frogs to prolong their breeding season and also increase the amount of suitable breeding sites (they are determined to be suitable by the absence of predators or water presence since water is required for the offspring to survive).

[14] The process of constructing a nest for the offspring is used as a method of promoting a male’s reproductive benefits to the females.

This parasite was more prevalent during the dry season which is primarily due to the water speed decreasing thereby allowing more potential breeding sites created.

Within this species, male goliath frogs were found to be more significantly infected when compared to the females which can be due to the weight difference between the two.

Liver weight was examined to reveal that there is a higher accumulation of toxic products at Loum due to the significant increase in agriculture practice.

Additionally, the direct life cycles of the helminths may play an important role in species diversity.

These types of parasites also often lack an intermediate stage which means that they must be able to survive in the outside environment as well and be able to establish themselves within a new host.

This ability to adapt to new environments contributes greatly to the complexity of helminth communities of goliath frogs.

Amphibian skin is vital because it is physiologically active meaning it plays important roles in regulating respiration, water, and electrolytes.

This fungus is also transmittable since it can be directly transferred through contact between frogs and tadpoles or through exposure to infected water.

[21][22] The goliath frog contains extensive skin folds to promote respiratory gas exchange at high altitudes.

[citation needed] In addition to the impacts of climate change, agriculture, and deforestation, goliath frogs are also threatened by the local practice of hunting them for food.
