photo of pharyngeal teethThe torpedo-shaped grass carp (native to China) can weigh up to 32 kg and feeds on water weeds which it grinds effectively with its strong molar-like pharyngeal teeth (right) located at the throat region.

It is an important food fish in many countries. It is not yet known to breed naturally here. It has been used to control aquatic vegetation in China, the Soviet Union and eastern Europe, and is reputed to be the most efficient plant eating fish known. In some countries where it is regarded as a potential pest, however, its release is forbidden.
