Author: Müller and Henle, 1837
Field Marks:
Rostral saw and barbels, five pairs of gill slits, two spineless dorsal fins and no anal fin.
Diagnostic Features:
Five pairs of gill slits. Large rostral sawteeth without posterior serrations. Teeth without prominent transverse ridges on basal ledges.
Remarks:
The present systematic arrangement of Pristiophorus follows Springer and Bullis (1960) with modifications. Dr Bruce Welton (pers.comm.) notes that he examined specimens of a Pristiophorus collected in deep water in the Arabian Sea while in Karachi. The identification of these specimens is uncertain, and could represent a new species of sawshark.
