Sex-changing clownfish!

These famous little fish change sex several times during their lifetime from asexual to male to female. Yes everyone, Nemo was a sex-changer.

You might have heard that some fish change sex. In fact, around 25% of tropical reef species do, including the Orange Clownfish (Amphiprion percula) of Finding Nemo fame. These little fish live among the poisonous tentacles of sea anemones and can change sex twice in their lifetime — from asexual juvenile to male, and from male to female.

For Orange Clownfish, size confers dominance – bigger is better. And as females are bigger than males, they’re also more dominant. A single female and male form a cosy monogamous straight relationship (don’t worry, it won’t last forever) and live together in their poisonous anemone along with some various sized asexual juveniles who float in on the current.

If the female dies or leaves (or like in the movie, gets eaten by a barracuda), the male starts to buff up, put on weight and changes sex to female. That same fish then becomes the new female of the anemone and one of the juveniles sexually matures and becomes a male to take her place.

So, you know, in the realistic version of the movie, Nemo’s mum got eaten, Nemo’s dad became his new mum and agender Nemo transitioned to male and married her. Really, I can’t imagine why they changed it.
