## Abstract

We, the NMFS, issue this final rule to designate critical habitat for the endangered Western North Pacific distinct population segment (DPS), the endangered Central America DPS, and the threatened Mexico DPS of humpback whales (Megaptera novaeangliae) pursuant to section 4 of the Endangered Species Act (ESA). Specific areas designated as critical habitat for the Western North Pacific DPS of humpback whales contain approximately 59,411 square nautical miles (nmi\2\) of marine habitat in the North Pacific Ocean, including areas within the eastern Bering Sea and Gulf of Alaska. Specific areas designated as critical habitat for the Central America DPS of humpback whales contain approximately 48,521 nmi\2\ of marine habitat in the North Pacific Ocean within the portions of the California Current Ecosystem off the coasts of Washington, Oregon, and California. Specific areas designated as critical habitat for the Mexico DPS of humpback whales contain approximately 116,098 nmi\2\ of marine habitat in the North Pacific Ocean, including areas within portions of the eastern Bering Sea, Gulf of Alaska, and California Current Ecosystem.
