We get a whole new form of life on the 5th day. Things that fly and swim. Things in the air and in the water.
Again, so much variety on offer. So many details all coming together in one day. You might not see the expanse of day 4... but the color's, the details, the variety. Any chance you get to look through binoculars, or snorkel though the coral will open your eyes to a wonderful kind of beauty.
