Summary
The smalltooth sawfish is a cartilaginous fish that belongs to the Subclass Elasmobranchii, which also includes all sharks and rays. This dorsally tannish-brown fish can reach a total length of up to 18 feet (5.5 meters) including the saw (Bigelow and Schroeder 1953). The species’ common and scientific names are derived from its long, flattened, toothed rostrum (nose or beak structure) that extends outward from its flattened head. The rostrum resembles a saw because it has 24–32 unpaired saw teeth on each side. Rostral teeth that are lost will not grow back; however, chipped teeth will continue to grow as long as the base is intact (Slaughter and Springer 1968). The mouth teeth are small and flat like other rays. The smalltooth sawfish is considered a type of ray, in part because the gill slits are located on the bottom of the body and the pectoral fins are attached to the head.
