Mangroves line the shorelines of Puerto Rico and its many island keys, where ever the wave action is limited. The most noticeable are the red mangroves that grow from the shore into the salt water, supported by a tangle of prop roots.
The roots not only support the plants but catch debris, leaves, and sediment floating by which supports a community of organisms that feed on it. This is further enriched by droppings of the birds that roost in the mangrove branches at night.
While the mangrove forest above the water supports a terrestrial community of life, the maze of roots below the water line offer protection for small fish and invertebrates that make up the underwater community.
Red Mangroves grow together in such density that you could never walk through them, but they make intriguing island waterways for kayaking.
It was a quiet on this particular day in the mangroves, no birds or fish to be seen. But there was a pretty terrific sunset.
