On strong windy days here in Miami, the warm Caribbean ocean churns like a washing machine, and pulls all the seaweed out of hiding. Though it is a nuisance when swimming, the mix of colors against the green and blue water is appealing. I exit the sea with seaweed in my hair like a true mermaid, and usually find some hidden in my bathing suit when I get home.
I brought some seaweed home recently for further examination. I left it sitting on a table, and within the hour it had shriveled up to nothing. I revived it in a bowl of water. It made me realize how much it needs water for its existence, much like us humans. Without water, seaweed shrivels up and dies.
Here is another version of darker seaweed in the beautiful blue ocean.
