Description

The giant freshwater pufferfish (Tetraodon mbu) is the largest freshwater puffer of the family Tetraodontidae and occurs in the Congo basin and Lake Tanganyika in Africa. The species has a stocky, disc-shaped body with a spectacular maze- or mosaic pattern in brown and yellow and reaches about 67 cm. It inhabits large rivers and lakes and also occurs in estuaries. With its powerful incisor teeth it crushes snails, mussels and crustaceans. Like other puffers it can inflate, and its tissue contains the potent poison tetrodotoxin; the species is therefore not eaten.
