The abdomen and ventral part of the limbs are yellowish orange (Boulenger 1906 - Annals; Channing and Rödel 2019). Larval development takes approximately 3 months to go through metamorphosis (Zahl 1967; Sabater-Pi 1985). The hindlimbs are powerful and long relative to the body length (~150% of snout–vent length; Sabater-Pi 1985). 2019). ''African biodiversity hotspots: the amphibians of Mt.

''Descriptions of new batrachians discovered by Mr. G.L. These interactions were only observed during the day and ranged from occurring once per week to as rarely as every three or four months.Since their discovery, goliath frogs have proved fascinating to scientists and the public alike (Boulenger 1906 - Proceedings; Krüger, 1912), inspiring work both in the field and at zoos and aquaria (Gewalt, 1976, 1977; Pawley, 1987) and many popular articles (Sabater-Pi, 1962, 1967, 1972; Zahl, 1967; Ruoso, 2018).

There is a strong dermal fringe on the outer side of the fifth toe (Boulenger 1906 - Annals). ''Exhibition of a specimen of, and remarks upon, a giant frog from Cameroon.'' Sabater-Pi, J. In captivity, when fed young mice, frogs have been observed to feed out of the water, though will also feed while their bodies are submerged in the water, capturing prey on the water’s surface (Pawley 1987). ''In quest of the world’s largest frog.'' ''Natatanuran frogs used the Indian Plate to step-stone disperse and radiate across the Indian Ocean.'' These may be sometimes accompanied by vocalizations varying between guttural calls (1.6 – 2.3 kHz) and high-frequency squeaks (4.5 – 5.8 kHz) (Pawley and Hutchison 1989; Hutchison, 1998).
