J.D. Anderson 1957 Ambystoma macrodactylum Nov. 18. Valencia Canyon, Rio del Mar, Santa Cruz Co., Calif. Temp data continued # cl. temp 1/4 lt not marked 12.0 - collected 12.6 13-2 also seen as I walked the road: 5 Batrachops, 2 giv. Ensatina, many snails, many slugs, 7 millipedes, many Daddy-Long-legs, many earthworms, 5 Hyla regilla. Many Hyla heard singing in oak woods but only 5 seen. Almost all ♂♂ frogs showed a definite defense reaction. When first looked at they usually snapped looks to a ♂♂ snake. Some would attempt to run - which they can do well in short, wild bursts. Those which assumed ♀ shape, slowly wound tail (actually wove around along tail). While, sticky secretion poured out along lateral surfaces of tail. This frequently brought into contact with hand. This secretion is as thick as on Ensatina but is restricted here to sides of tail. Unable to get stuff off hands for 12-24 hours. All due ♂♂ I consider to be just approaching aquatic stage (for reproduction). They avoided puddles however. And when put in puddle left it immediately.
