The sawfish uses its saw to catch prey in two ways; firstly by using it as a rake to sift through the sand for crustaceans such as crabs and shrimps, and secondly by using it as a sword to swipe through schools of shoaling fish such as mullet, lacerating or stunning individuals. The smalltooth sawfish is predated on by sharks, but only when it is young and undersized (2) (3).
Little is known about the life cycle of the smalltooth sawfish but it is thought to breed year round in areas of constant climate, but elsewhere, only in the summer. Fertilisation is internal and the pups develop inside the female, who gives birth a year later to 15 to 20 pups. The saws of the newborns are sheathed and malleable at birth for protection. The pups are around 60 cm long at birth (3) (4) (5).
