Description
This large-toothed, highly predatory fish grows to an average length of 1.5 m (4.9 ft) and a weight of 50 kg (110 lb).[6] Its teeth fit into distinct grooves along its jaws. On average each of its teeth can grow up to 2.5 cm (1 in),[4] according to biologist and television presenter Jeremy Wade.[6] The largest recorded specimen weighed 70 kg (154 lb).[4]
Diet
Hydrocynus goliath is a piscivore, feeding on any fish it can overpower, including smaller members of the same species.
When hunting, this fish uses the calmer eddies of the rapids to ambush its prey, using its keen sight to detect prey. When a target is noticed, the fish accelerates to chase it down. The Nile crocodile is the only known predator of mature goliath tigerfish.
