Unlike most other frogs and toads, goliath frogs have no vocal sac and therefore courtship does not involve displaying any calls (2). Females lay large clutches of several hundred eggs onto vegetation on the river bottom (3). Once the tadpoles hatch they feed on the food plant, which is only located near to waterfalls and rapids (2). It takes around 85 to 95 days for complete metamorphosis into the adult form (3). Adults feed on insects, crustaceans and fish (2).
