12-Month Finding on Petitions to List the Common Thresher Shark and Bigeye Thresher Shark as Threatened or Endangered Under the Endangered Species Act

AGENCY: National Marine Fisheries Service (NMFS), National Oceanic and Atmospheric
Administration (NOAA), Commerce.


ACTION: Notice of 12-month finding and availability of status review report.

SUMMARY: NMFS has completed comprehensive status reviews under the Endangered
Species Act (ESA) for two species of thresher shark in response to petitions to list those species.


These species are the common thresher shark (Alopias vulpinus) and the bigeye thresher shark
(Alopias superciliosus). Based on the best scientific and commercial information available,
including the status review report (Young et al., 2015), and after taking into account efforts
being made to protect these species, we have determined that the common thresher (A. vulpinus) and bigeye thresher (A. superciliosus) do not warrant listing at this time. We conclude that neither species is currently in danger of extinction throughout all or a significant portion of its range nor likely to become so within the foreseeable future.
