We, NMFS, issue a final determination to list the largetooth sawfish (Pristis perotteti) as endangered under the Endangered Species Act (ESA) of 1973, as amended. We do not intend to propose to designate critical habitat for the species. We have reviewed the status of the species and conservation efforts being made to protect the species, considered public and peer review comments, and we have made our determination that the largetooth sawfish is in danger of extinction throughout its range, and should be listed as an endangered species, based on the best available scientific and commercial data.
