Hi Doug, Alina,
So what about the Bay Islands reef? I've always been told that it was
connected to the Belizean reef. Is it then not a barrier reef? The reef of
the Swan Islands is a bit far to connect it to the MBRS, but now I just
don't know.
And yes, fringing reefs are spectacular. The reefs of Cayos Cochinos are
nothing less amazing.
Cheers,
