D. Anderson 1955 Ambystoma macrodactylum Feb 27. Rio del Mar, Santa Cruz Co., Calif. 1:40 P.M. an adult female was collected under a flat board 14" square. The board rested on some fallen branchlets and was not in contact with the soil but about 1 1/2" off the ground. The situation was on the edge of an oak woods with a road directly to the east, and Oakwood Inn up on a hillside immediately west of the locality. Conopy cover was about 50-60 %. Quercus agrifolia seemed to be dominant in immediate vicinity. The ground gravid - eggs visible through the body wall. Air temp - 8° C Soil temp - 9.6° C Ambystoma - 9° C. When placed on the leaf litter on the oak wood floor the broken stripe pattern was an effective camouflage agent. The black ground color melted in with the soil & decaying leaves. The broken yellowish pattern blended perfectly with the many dead oak leaves littering the substrate. No attempt to escape + no defense reaction noted.
