Unlike the rest of the cartilaginous fishes, sawfish have evolved a long snout edged with special teeth. The saw-like snout, called a rostrum, can be used in a back and forth swiping motion to cut prey in half or to dig through the sediment.
There are two species of sawfish which used to be found in Zimbabwe
- Green Sawfish (Pristis zijsron) and the
- Largetooth Sawfish (Pristis perotteti).
