To my knowledge it has not been done and little is known about these amazing creatures. The more we find the more we want to know. Their prime habitat has been taken away from them which are now Homes, Dairies, Hospitable's, Roads. Not to Mention Animal Fecal Runoff, Pesticides, And the Biggest is "Ignorance" to the degradation of surface water runoff. They are very sensitive to water quality. I had a baby salamander for several months, in this short period of time he had grown to extremely large size 11" to 12" feed night crawlers and he was no more than 6 months old. I Thought he would like some branches in his environment to climb on ect. He was dead within an 1 hour be cause of the toxic tan-ins
in the redwoods. Now they live in the middle of the red woods, go figure. I saw a female in the middle of the night foraging for food in the rain she was 14" long and pure white not an albino but her camouflage had swiched to white. They are very good at camo. Phase shift very subtle within 1 minute. They can travel great distances. We had just turned onto Hwy 1 traveling inland along the coast at about 1 mile spotted a rare Santa Cruz Salamander doing what I would call a salamander slow jog. He was headed down this mountain on the flat of the road just stating to cross on my side, as we passed him he was at the edge heading down, this angle downward was hard to imagine anything going down without a serious roll, how he got up was sure determination.
