I was a college kid on spring break in the Florida Keys the first time I looked through a snorkel mask and spotted a tropical fish. It was a parrotfish, in candy hues of lime, yellow, and pink. I had no idea such a wondrous creature could be found right here in the United States, and when my four nieces and two young children were old enough to breathe through a snorkel tube, the first place I took them to spark their love for the ocean was to the warm, clear waters of the Florida Keys.
