Green Mermaid's Wine Glass Algae

Habitat:

shallow protected areas of reef, coral rubble, sea grass beds adjacent, sand flats, and mangroves.

Notes:

There are numerous small clumps of these through out this area both on the sand and on some scattered boulders. They and all the sea grass here seems to be coated in this dusty beige algae that seems to be "chocking" everything. I'm not an expert but it seems the ecosystem is not healthy, most likely from water pollution from the city and reduced biodiversity. (ex. I did not see any sea urchins at all. I used to see and average of 4 or 5 while snorkeling on the sea grass. Not as many crabs or mollusks as I use to see either.) I found this article: https://www.miamiherald.com/news/local/e...
