Species. Approximately 2,215 species are listed as endangered or threatened under the ESA. Of these species, about 650 are foreign species, found only in areas outside of the U.S. and our water s. We have jurisdiction over 129 endangered and threatened marine species, including 42 foreign species. We work with U.S. Fish and Wildlife Service (USFWS) to manage ESA-listed species. Generally, we manage marine species, while USFWS manages land and freshwater species.
