40 Species for 40 Years of the Endangered Species Act

This December marks the 40th anniversary of the Endangered Species Act (ESA). Congress passed the ESA in 1973 to protect threatened and endangered species and their ecosystems. There are approximately 2,100 species listed.

The U.S. Fish and Wildlife Service (USFWS) and NOAA Fisheries share responsibility for implementing the ESA. Generally, USFWS manages land and freshwater species, while NOAA Fisheries manages marine and anadromous species from whales and sea turtles, to salmon and sea grass.

Take a look at our slideshow below to learn more about some of these endangered and threatened marine species.
