Throughout the entire Mangrove swamp, the water is a dark red brown color. Apparently, tannins in the roots of red mangroves actually dye the water, making it so opaque it’s difficult to see more than about a foot down. From South Joe River Chickee to Oyster Bay Chickee, the water has become gradually more brackish as we approach the Gulf of Mexico. Accordingly, the aquatic wildlife has been changing. During the day we spotted several bottle-nosed dolphins surfacing for air. Our current campsite seems to be home to a collection of small crabs, needle-nose fish, barnacles, oysters, and jellyfish. Also, we’re situated on a tract of water called the Shark River, infamous for its bounty of black-tips. Unfortunately this shot down our hopes of an afternoon swim.
