When we stayed Clearwater beach FL, in '09, we stayed in luxury rental home on Bayside Dr. Gorgeous house with a dock out into the bay. Under the dock there was bright fish light that came on at dusk. It was one of my favorite places to sit at night. All sorts of fish came to that light, I saw a huge what I believe was grouper, sea bass, sea horses, sea sunfish and one night a dolphin.
Getting to that dock was pain though, there was no lighting beyond to pool. So you were in dark and I walked into massive spider web at night. It's deep water bay and I'm not good swimmer. I stood still, until I got all webbies off my face and arms. A huge banana spider ran off the dock into water. A big fish came up from darkness grabbed that spider and spit it back out. Must have tasted terrible.
The second to last night we were there; I was sitting out on the bench seat watching the water and fish. My brother walked down to seeing what I was watching. Right in front him there was snake on dock, not huge just little half footer, it slithered along to end of the dock and dove in. A Copperhead we watched it as the big fish went after it but they seemed to know to leave it be.
