Overview
Main identification features
  • saw: 17-20 teeth rows
  • dorsal fin origin before pelvic origin
  • c: with lower lobe
Body shark-like with two nearly equal-sized dorsal fins; head flattened; 17-20 teeth on each side of saw-like snout; a large spiracle behind each eye; pectoral fins broad and triangular; tail fin shark-like with large upper lobe and small, but pronounced lower lobe; origin of first dorsal fin well forward of pelvic fin origin.

Dark grey to golden brown, whitish on ventral surface; specimens in freshwater are pale grey.

Grows to about 650 cm and estimated weight of 590 Kg.

Inhabits shallow bays and estuaries, also entering rivers.

Depth: 1-10 m.

Eastern Pacific and the east and west Atlantic; in our region from the southern Gulf of California to Peru.

The status of the species in the eastern Pacific is questionable. We treat it as P. pristis, which elsewhere occurs in the Atlantic. However, it may be a separate endemic species P. zephyreus.

While there are reports of a second species of sawfish, P. pectinata, in the eastern Pacific, that has yet to be unequivocally demonstrated. P. pectinata lacks a definite lower lobe on its tail fin, has 25-32 teeth on each side of the saw, has narrow, angular pectoral fins, and has the origin of its first dorsal fin directly over that of the pelvic fins.

Taxonomic Decision for Synonymy

 

Generic Combinations

 

Introduction

A recent study by Faria et al . (2012) found no differences between various populations of Pristis pristis and Pristis microdon , resulting in the inclusion of Pristis microdon as a junior synonym to Pristis pristis . The species was listed as Critically Endangered by the IUCN in 2012 for Pristis pristis from the Atlantic and Eastern Pacific and Critically Endangered for the Indo-Pacific populations in 2006 (as Pristis microdon ). In Australia, the species is listed as Vulnerable under the Environment Protection and Biodiversity Conservation Act 1999 under the name Pristis microdon .
