The little "bushes" look like an epiphytic red alga.

A sponge about 1 foot long, dead man's fingers has finger-thick branches attached at a thin wrist. It's an animal with no brain! This specimen was found in the shallows at North Lido Beach.
This tiny stone crab (approx. 1 inch) was in a tidal pool at Bird Key.

A spider crab appears.
Here's a baby (blue?) crab.
... and this puffer fish is ticked off.
The puffer is believed to be the 2nd most poisonous vertebrate in the world.
The cabbage palm is leaning slightly over the edge of the Inland Waterway at Nokomis Beach. Water is eroding the sand away from its short outer roots. Despite the existence of a few, long (10-15 feet) central roots, the tree is in danger of falling into the water.
Now, look at this... The strangler fig has wrapped its roots around the palm. No danger of falling into the water now!
Go on Bud's Nokomis Beach walk. The story is better when he tells it.

What are the "icicles" hanging down off the bottom of this rock/concrete slab? The rock is on a beach and is out of the water at low tide. It has been a mystery for over a month, now. I came upon the answer when looking for something else. 
Buttonwood live farther from water than red, black, and white mangrove. They are usually found above the high tide line. The fruit and flowers do not remain long, but are distinctive when seen.
L 26". Adult back, wings, neck, and head are slaty blue. The belly and underwings are white. There is a white line down the entire foreneck and the base of the neck is purplish. The neck and legs are long; the bill very long, thin, gray, and black-tipped. During courtship, the tri-colored has long, buffy plumes on back. It fishes by slow stalking and wild running pursuit in shallow water.
Probably sea pork, a colony of tiny tunicate animals known as zooids.
This species of brown sargassum has berrylike, gas-filled bladders
The body actually consists of five equal segments, each containing a duplicate set of various internal organs. They have no heart, brain, nor eyes, but some brittle stars seem to have light sensitive parts on their arms. Their mouth is situated on the underside and their anus on top.

Each year, thousands of feet of fishing line become entangled on Sarasota Bay’s bird nesting islands and shorelines and pose a fatal hazard to birds and other wildlife. This cleanup event, co-sponsored by Save Our Seabirds and Audobon of Florida, helps to reduce the threat of entanglement while recycling the fishing line. Volunteers will remove snarled fishing line from mangroves and shorelines of Sarasota Bay’s colonial bird nesting islands.
