DISTRIBUTION .— Conraua goliath is distributed over south-western Cameroon (Nkongsamba region) and mainland Equatorial Guinea . In Equatorial Guinea , it has been recorded in several localities in Río Muni ( Sabater Pi 1985 ; De la Riva 1994 ) ( Map 14A ). COMMENTS .— This is the largest living frog in the world. The holotype measured 25 cm of snout-vent length ( Boulenger 1906b ), and the largest specimen recorded weighted 3.3 kg ( Sabater Pi 1985 ). Adults live in the fast-flowing rivers in lowland rainforest, below 1000 m a.s.l., where they rest over the rocks, emerging from rapids during the day, while they move along the river margins during the night ( Sabater Pi 1985 ). Some aspects of their reproductive behaviour, such as nest construction for spawing, have been recently described ( Schäfer et al. 2019 ). SPECIMENS EXAMINED .— Twenty specimens .
