Tidewater Goby

The endangered tidewater goby (Eucyclogobius newberryi) is endemic to the coastal areas of California. As a result of loss of habitat, changes in water quality, introduced predators, and drought, gobies can now only be found in about half of the places where they once lived. Gobies are bottom-dwelling, and prefer the sandy shallows of slightly brackish coastal lagoons, estuaries, and marshes—including several sites within the San Francisco Bay Area national parks. Because they are endangered, the parks are responsible for maintaining and protecting these populations.
