Abstract
The Largetooth Sawfish, Pristis pristis (Linnaeus, 1758), is not extirpated from Peru: new records from Tumbes
Highlights
The Largetooth Sawfish, Pristis pristis, was for a long time considered extirpated from Peru
All extant sawfishes belong to the family Pristidae, which includes the genera Anoxypristis White & MoyThomas, 1941 and Pristis Linck, 1790 (Compagno and Cook 1995)
Recent studies have shown that P. perotteti from the Atlantic Ocean and P. microdon from the western Indo-Pacific Ocean are synonyms of P. pristis
Summary
All extant sawfishes belong to the family Pristidae, which includes the genera Anoxypristis White & MoyThomas, 1941 and Pristis Linck, 1790 (Compagno and Cook 1995). Sawfishes live in shallow coastal waters usually at depths up to 20 m but as deep as 122 m (Harrison and Dulvy 2014) They can tolerate wide ranges of salinity and can be found in continental waters and estuaries. Recent studies have shown that P. perotteti from the Atlantic Ocean and P. microdon from the western Indo-Pacific Ocean are synonyms of P. pristis. This eurohaline species, as currently defined, has a circumtropical geographic distribution with 4 genetically differentiated populations: eastern Pacific, western Atlantic, eastern Atlantic, and western Indo-Pacific Ocean (Faria et al 2013)
