I was hopeing that someone could give me some clues on sexing sub adult and adult California red-legged frogs (CRLF). Or a close specie in the same genus Rana might be helpful.
I've tried books and articles, but don't seem to be getting any where.
I know that the adult male forms a or has a nuptial pad on its' thumb. What about the sub adults (M/F) and females during non-breeding years?
