Interesting question.
The top three largest coral reef ecosystems in the world are:
1) Great Barrier Reef off the coast of Australia
2) Belize Barrier Reef
3) Florida Keys Reef Ecosystem
A coral reef ecosystem relies on teamwork between the coral animal (a type of cnidarians) and an algae called zooxannthellea.
Yeah, I get to go to Belize this week. So excited.
That’s wonderful! Can you take a picture to share with this post? Have fun.
