I know little about breeding snakes other than what I’ve read here and on other forums, so this statement very much intrigued me.
Question: is this phenomena something that is observed as a constant and a rule, or is it something that is observed only occasionally or even rarely?
I ask because the study of sexuality is something I find fascinating. For over a century the mainstream scientific community turned a blind eye to the existence of various forms of sexual orientation within the family animalia, chalking the occasionally observed instances of non-heterosexual relations as ‘confusion,' ‘dominance behavior’, et al. even when observed among species that pare-bond for life, in habitats with an abundance of available opposite-gender partners.
A great book on this topic, sourcing hundreds of observed and verified international case studies spanning over a century, is: Biological Exuberance, by noted biologist Bruce Bagemihl. There are several reptiles mentioned, from lizards to snakes.
Just to be clear, I am not suggesting that all instances of non-heterosexual behavior are automatically signs of a variance in sexual orientation.
