The giant slippery frog (or Conraua goliath), sometimes called the goliath frog, is an extremely large species of frog that lives in the African rainforests of Cameroon and Equatorial Guinea, specifically in the fast-flowing rivers and streams.

It can be green to dark brown in colour, with a paler underbelly, large yellow eyes, and may also have small, ridged bumps on its skin.

Males are larger than females, weighing between 0.6kg and 3kg and measuring between 17cm and 30cm long.

Giant slippery frogs are solitary and do not interact except to mate or compete over mates.

Release

Conservation

The species is Endangered due to being over-hunted for food, as trophies and large-scale collection by the pet trade. It is also subject to loss of habitat from agriculture, logging, road traffic and human settlement. Sedimentation and pollution of its breeding streams affect tadpole development and plant species essential to feeding tadpoles. The frogs react erratically when disturbed, likely affecting breeding further.

Protected areas across the habitat range for the broader ecosystem are beneficial for the conservation of the giant slippery frog.

This species is in rapid decline due to over-harvesting, and work is needed to engage local communities in sustainable harvest practices. Captive breeding programs should also be considered.

Breeding

Giant slippery frogs have an unknown specific breeding season that is likely annual. When females are ready to lay eggs, males will build nests on river beds near fast-flowing water, pushing stones into semicircular formations in the sand. They will also wrestle with any rival males that happen to be building nests nearby. It is then up to females to decide on a high-quality nest in which to lay her eggs, the male fertilising them as she does so.

Both the mother and father will abandon their eggs after laying, leaving them to hatch into tadpoles that will then grow into froglets approximately 3 months later.

The young frogs will reach sexual maturity at 10 to 12 months old.
