Endangered and Threatened Marine Species

Overview

NOAA's National Marine Fisheries Service (NMFS) and the U.S. Fish and Wildlife Service (USFWS) share responsibility for implementing the Endangered Species Act (ESA).

There are approximately 2,140 species listed under the ESA. Of these species, approximately 1,515 are found in part or entirely in the U.S. and its waters; the remainder are foreign species.

Generally, USFWS manages land and freshwater species, while NMFS manages marine and "anadromous" species. NMFS has jurisdiction over 93 listed species (73 of these species are found in part or entirely in U.S. waters; 20 are foreign species) (see links below).

The ESA requires NMFS to designate critical habitat and to develop and implement recovery plans for threatened and endangered species. 

For more information on the ESA, see our ESA Fact Sheet [pdf].
