I never knew this about clownfish or any other type of fish. It's not just the gender-changing, it's that they can both lay eggs and fertilize them, depending upon which phase they're in. Most creatures do not carry the equipment for both. Not that I'm going to research what's up with slugs and snails, to see if that's a different thing!
