(Along) the curve of islands known as the Florida Keys (lies) a reef of living coral, (the only one) of (a kind) in the continental United States.
Why is (a kind) wrong? It sounds alright even if its kind would be a better alternative. but no style points in this section, right?</p>
<p>Should be (its kind), I think.</p>

<p>The only one of a kind, doesn't make sense in context. It is reffering to the curve of islands known as the Florida Keys (the subject), so it should be "it's" kind. Hope that helps.</p>
<p>Oh good call. Its not It's aka It is.</p>
