Endangered and Threatened Species; Identification of 14 Distinct Population Segments of the Humpback Whale (Megaptera novaeangliae) and Revision of Species-Wide Listing

We, NMFS, issue a final determination to revise the listing status of the humpback whale (Megaptera novaeangliae) under the Endangered Species Act (ESA). We divide the globally listed endangered species into 14 distinct population segments (DPS), remove the current species-level listing, and in its place list four DPSs as endangered and one DPS as threatened. Based on their current statuses, the remaining nine DPSs do not warrant listing. At this time, we find that critical habitat is not determinable for the three listed DPSs that occur in U.S. waters (Western North Pacific, Mexico, Central America); we will consider designating critical habitat for these three DPSs in a separate rulemaking.
