J.D. Anderson 1958 Ambystoma m. croceum Jan 9. Valencio Lagoon, Rio del Mar, Santa Cruz Co., Calif. regilla was sitting partly exposed in one of their holes. The Ambystoma were in a ball facing in no one particular direction. The sandy soil was here, very moist & indeed there was a film of free water in bottom of pocket. Sand in this area had enough water to squeeze out. The Ambystoma were all in fine shape as contrasted to Ensatina found on surface. These were very desiccated. see Ensatinia notes 9-Jan. Temp just outside pocket at surface of soil = 7.4°C. Temp 2" below surface - approximating level of Ambystoma = 6.2°C. Cl. temps of A.m. croceum taken from this depression: 7.0, 7.0, 7.0, 6.8, 7.0, 7.2, 7.0. shelt \/ side of pit Ambystoma pocket This pocket was obviously of great value for survival.

I'd say yes! There was a little more room in it & 1 ad of Ensatinia was sitting at edge, she was in bad shape. Something about presence of Ambystoma kept her
