90-day petition finding, request for information, and initiation of status review.


We, NMFS, announce a 90-day finding on a petition to list the scalloped hammerhead shark (Sphyrna lewini) or, in the alternative, multiple distinct population segments (DPSs) of the scalloped hammerhead shark as threatened or endangered under the Endangered Species Act (ESA), and to designate critical habitat concurrently with the listing. We find that the petition and information in our files present substantial scientific or commercial information indicating that the petitioned action may be warranted. We will conduct a status review of the species to determine if the petitioned action is warranted. To ensure that the status review is comprehensive, we are soliciting scientific and commercial information pertaining to this species from any interested party.

    Together, smooth and scalloped
    hammerheads are estimated to comprise 4–5 percent of the total fins traded in the Hong Kong market, which suggests that 1.3 to 2.7 million individuals of these species (equivalent to a biomass of 49,000–90,000 tons) are used in the Hong Kong fin trade annually (Clarke et al., 2006; Camhi et al., 2009).
