Goliath Tigerfish Hydrocynus goliath

Tigerfish, large fish with exposed sharp teeth, are sometimes referred to as Africa's Piranhas. The Goliath Tigerfish is native to the Congo river basin system and to Lake Tanganyika.

It can reach 1.5 metres long (70kg weight). It has no lips so its sharp teeth are exposed (and it keeps replacement teeth in its jaws to replace those lost or broken).

It is a ferocious hunter that circles its prey before it kills and is said to attack humans and crocodiles. (The slightly smaller - 1 metre long - and more stripey African Tigerfish, H. vittatus, is known to hunt in packs to kill large prey and to leap out of the water to take low-flying birds.)
