Recent attempts to locate salamanders in these areas indicate that it is likely that these populations are no longer in existence. ![]() At least two other populations of tiger salamanders once existed in the Stanford area, most notably one centered in the wetlands formerly located in Portola Valley, near the intersection of Indian Crossing and Alpine roads. It is believed that the salamander population on the Stanford University campus represents the only population remaining on the San Francisco Peninsula. Each egg is approximately 0.5 to 0.75 of an inch in diameter, including a thick gelatinous layer.Ĭalifornia tiger salamanders range from the eastern foothills of the Sierra Nevada, west to the outer coast range, from Sonoma and Yolo counties in the north, to Santa Barbara County in the south. Larval tiger salamanders have external gills and are olive green in color, generally with very fine dark markings (stippling).Įggs are laid underwater singularly or in small groups, on subsurface portions of emergent vegetation or other debris. Juveniles are dark olive green in color and do not generally have any lighter markings. Adults are black or dark grey, with oval to bar-shaped spots ranging in color from white to yellow. ![]() These are thick-bodied salamanders with broad heads and blunt snouts. California tiger salamanders are large salamanders, with adults frequently reaching 7.5 inches or more in total length. ![]()
