I had never heard the Channel called the "English" Channel before I found this site. I still don't understand why it would be specifically be called English when it's not specifically IN a country...
I'm a bit surprised about the diversity answer. I thought some Chinese at least would have made their way across the border in the centuries before the war, and perhaps a Japanese or two. Ah well, evidently my own guess was wrong, those swarthy Liechtensteiners from that country's far south make for plenty of diversity, it seems.
It could be a nudibranch. Which should probably be accepted, on the off-chance that some smart person types 'nudibranch' when they were thinking 'slug' :D
I think the Indonesian rainforest has been so badly depleted it is no longer in the top five. Two sources list the Democratic Republic of the Congo as second to Brazil.
Should either accept these, or maybe add a compiled language to broaden the scope?
