Knife tooth saw fish
The knifetooth sawfish (Anoxypristis cuspidata),is also known as the pointed sawfish or narrow sawfish
The knifetooth sawfish grows to a maximum length of about 4.7
metres (15 ft). Its body is generally shark-like but its most obvious
feature is the flattened head which is extended forward in a blade-like bony
snout 25 pairs of sideways-facing teeth.
The knifetooth sawfish is distributed across a broad swathe
of the Indo-Pacific Ocean. It is present in the waters off Iran, India, Sri
Lanka, Bangladesh, Malaysia, Burma, Indonesia and Papua New Guinea
The knifetooth sawfish feeds on small fish, squid and
invertebrates such as crabs and shrimps.
It is itself prey to various sharks such as
the hammerhead shark (Sphyrna spp.),
the bull shark (Carcharhinus leucas) and the copper shark.
Pregnant females and juvenile knifetooth sawfish are
particularly susceptible to entrapment in fishing gear and this is the major
threat faced by this fish.
Overfishing and
habitat degradation through urbanisation of the coastline also put this species
at risk and the population trend is downward.
For these reasons, the IUCN have listed this fish as "Endangered" in its Red List of
Threatened Species
