Nice quiz! Surprised to see tiny Oceania countries on here but not big ones like Brazil.

They're big in terms of ocean expanse I guess.

Coral grows (best) in warm water, and coral reefs in shallow, clear water (so it gets sun). So it's more a function of proximity to the right growing conditions than it is to total length of coastline.

The north African/Arabian areas surprised me. Never thought about the Red Sea having reefs.

The Red see is beautiful for reefs. Great snorkelling and the bluest waters.

Completely failed to take overseas territories into account. Still, managed 15/20, I'm fairly happy with that.

I always thought Belize was known for its coral reef, but I guess it's not very large.

Bit surprising that Belize is considered to have the second largest coral reef in the world but doesn't make the top 20 in terms of overall reef square mileage

I feel like as a Queenslander, if there's one thing we should know its coral. Pretty much the main reason anyone comes here - the Great Barrier Reef. Managed to get them all in the end with about 30 seconds remaining. I was stuck for a while, but Egypt was a breakthrough and gave me Eritrea and Saudi Arabia.

No way the Bahamas has more than Mexico, I thought they had a lot.
