Information provided at the Birmingham Sea Life centre explains how reproduction on a coral reef can be complicated:

Clown fish start life as males and live inside a sea anemone, together with a female clownfish. The female prevents the males from changing sex by bullying them. When she dies, the largest male changes sex and takes over her role.

Wrasses, damselfish and antheas, not only change sex, but also colour! Unlike clownfish they are born females and later change into males.

Usually there is one male in charge of a harem of females. When he dies the largest female changes colour and becomes a male within a matter of days.

What an interesting concept…

    Hmm I am lost…
    Are you saying the a non-bully male can become a female, and “she” can be a partner of a dominant male, and one day when the alpha male dies “she” may become “he” again?
    In this case, boys will still be boys. ;)

    This is crazy! Ha ha

    Most interesting, indeed, Cherie. I often read about same-sex couples in the animal kingdom but this may be the first time I’ve read about transgendering in the animal world. WOW. So there IS a precedence in Nature. Amazing.

    Well I’m glad I don’t live in a sea anemone – life’s complicated enough just being one gender :)

    Sounds rather fishy to me!

    Great shot of the clown fish. Isn’t nature strange, weird, downright bizarre, but so, so interesting! Mickie :)
