Current Management Issues

On December 21, 2012, and March 15, 2013, petitions to list the great hammerhead shark (Sphyrna mokarran) under the ESA were received from WildEarth Guardians and Natural Resources Defense Council, respectively.

On April 26, 2013, NOAA Fisheries made a positive 90-day finding (78 FR 24701), determining that the petitioned action may be warranted. A comprehensive status review was conducted to inform the 12-month finding.

On June 11, 2014, NOAA Fisheries announced a not warranted 12-month finding (79 FR 33509), determining that the great hammerhead shark is a global population with no distinct population segments (DPSs), and the species does not warrant listing as threatened or endangered under the ESA at this time.
