  • Blue Gropers: Born Females And Can Become Males

    Science lesson  via National Geographic (check out the site for a video): The blue groper is a large fish, but the really sexy thing about blue groper is they start off as females. We've got lots of blue groper that are small green groper and as an old male dies then the largest most dominant females turns blue and becomes male. And so one of the really cool things about these fish, is the sex ratio doesn't really vary, but it is a function of how well protected they are. If you take a lot of males out, then the females have to spend a lot of their time turning into males, which means they can't breed and they can't lay eggs.

    Kinda amazing, and because it's one of two days a year I'm blessed with killer cramps, I wouldn't mind changing my gender right about now. brb, taking Advil because I am no blue groper.

    If you had the chance rightthisverysecond to switch your gender, would you?
