It is criti- cal to identify areas with valid historical records as these areas may be important to the recovery of the species. The U.S. range is reported to extend as far east as Florida based on one vouchered specimen and 3 historical records from this state. Three of these reports presume a local capture location despite a lack of locality data. The vouchered specimen was presumed captured in southern Florida, but evidence suggests otherwise. Dried specimens observed in Florida were most likely imported to Florida from the Indo—Pacific region, or from the Caribbean, for the marine curio trade. A vouchered rostrum, purportedly from Louisiana, lacks locality data and it cannot reliably be assigned to this state. We believe that the range of the Largetooth Sawfish in the U.S. never extended farther east than Texas, which was likely the northern limit of its range in the western Atlantic Ocean. Future conservation efforts should be directed to areas in Texas rather than states to the east where the species likely never occurred. KEY WORDS: Pristidae, Pristis pristis, conservation, endangered species, critical habitat INTRODUCTION Shark and ray populations in many areas of the world are Nearly all records of Largetooth Sawfish from the U.S. declining due to modern fishing practices and enhanced in‑ have been from the coast of Texas (Fernandez—Carvalho centives to target or retain these species, especially for the et al. 2013). Baughman (1943) stated that the species repro‑ fin industry (Camhi et al. 1998, Clarke et al. 2006, Lack duced in Texas waters based on captures of gravid females by and Sant 2009). Sawfishes (Pristidae) are at particular risk Texas shrimp trawlers. He considered Port Arthur, TX (on as their fins are among the most valuable (McDavitt 2005) the eastern border of Texas) to be the eastern extent of the and because sawfishes and other coastal sharks and rays are species’ range in the U.S. Similarly, Bigelow and Schroeder vulnerable to habitat alterations and pollution (Seitz and (1953), Walls (1975), and Thorson (1976) all considered the Poulakis 2006, Dulvy et al. 2008, Dulvy et al. 2014). Bycatch Texas—Louisiana border to be the eastern extent of its U.S. mortality in net fisheries was the major reason for the de‑ range. However, many other early authors considered Flori‑ cline in sawfishes worldwide (Stevens et al. 2000). Sawfishes da to be part of the range (e.g., Briggs 1958, Duarte—Bello were not part of a targeted fishery, except in the case of the 1959, Robins and Ray 1986), and this idea has been perpetu‑ historical Lake Nicaragua fishery (Thorson 1976, 1982), and ated by more recent regional fish guides (e.g., McEachran therefore did not appear in fishery statistics. As a result, the and Fechhelm 1998, McEachran and de Carvalho 2002, reduction in sawfish populations went largely unnoticed or Kells and Carpenter 2011). This opinion eventually became unaddressed by fisheries managers until recently.
