Mayhew 1947 Triturus granulossus L. May 10 Wildcat canyon, Contra Costa Co., Calif. One was seen at the bottom of a small pool just south of the Tilden Park golf course club house. It was setting motionless on the rocky bottom in about 12 inches of water. The temperature of the water was 12.5° C. The animal was very dark on the back + reddish-orange on the belly. (T. granulossus has a sharp line of color between back + belly, whereas T. torosus has a graded color between. Also, T. granulossus has a smaller eye [cornea doesn't reach the edge of the jaw], the iris is silvery [lemon-yellow in T. torosus]). Another one, smaller in size, was seen a little later in the same pool. The larger one was about 6" long, the smaller one about 4" long. Whatever movements either animal made were very slow + deliberate. They only moved one leg at a time. Water striders, whirligig beetles, + water boatmen were also seen in this pool. A stick was found with 7 egg masses attached. The young had already hatched, and the external gills were readily observable on the young within the capsule. The stick was found in a pool about 2 & 3" below the surface. The eggs were sheltered from the sunlight.
