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.
