Re: [GSAS-Member] Dr. Kallman and the Xiphophorus Stock Center link

Thanks for the links! After reading the biographical info, I think the
comment Dr. Kallman made last night re: sex reversal in fish being
explained by sloppy science referred to livebearer sex reversal. I learned
a new word refreshing my mind about this topic: gonochoristic...that's
what he said fish really are, i.e. fish are born one sex and stay one sex.
However, I don't think there is any debate about the existance of sex
change/reversal in numerous saltwater species, especially reef species
(shrug). I'm not as familiar with freshwater species. Others???
