I'm talking about their genetically encoded adaptation to living in temps that are much lower at night than we keep our captive iguanas at night. And the long-term implications.
Now I've found out that their natural habitat temps often dip into the 50's at night.
I wonder if they would have better lives if we fluctuated their temperatures to match that of their natural habitat?
But I suppose it could be that if their natural setting is sometimes stressful, then eliminating that stress could let them live better.
I'm thinking about this because of the mystery of why the captive iguana life-span is 1/2 to 1/3 that of their wild relatives. Most well cared for wild animals live longer than the wild ones.
I know that lousy care drastically shortens igs lives. But even most very well cared for captive igs only live to fifteen years. There are a few long-lived exceptions (26 YO), but these too are a mystery. Just wonderin'.
