Diet / Feeding

- Stuns prey by quick swipes of the saw.
- Shellfish and crustaceans are also consumed; sawfish will use its saw to sweep these animals out of the sand.
Range / Habitat
- Occurs in the Indo-West Pacific, Australia and Papua New Guinea, eastern coast of Africa and the Red Sea, as well as China and New South Wales.
- Mainly bottom-dwelling and found in shallow bays, lagoons and estuaries. Has been found at depths up to 130 feet (40 m), but 1-16 feet (0.3-5 m) is most common.
Reproduction & Growth
- It has been suggested (Grant, 1978) that adult males will use their saws in dominance and mating battles.
- Ovoviviparous species.

Conservation Status
- “Critically Endangered” on the IUCN Red List.
