looks like some salt creep and mangroves?...o and a brown extension cable.

 

there's a worm looking thing just under the water line. This is what I'm talking about.

 

I think we are going to need a higher resolution image. Its too small. All i see is a brown line, can't tell what it is. Is it moving? Can you describe it? Most worms stay in the substrate or rocks. They don't normally float.

 

It's about two inches long brown in color with feathery things at the end of it. It moves around pretty fast. If you go to my profile and look at my album you can get a better look at this thing. Thanks.

I stole some bigger images from his profile. A little better resolution. I don't know what it is.

 

Looks like some kind of spaghetti worm. Google spaghetti worm and see if that's it.

I'm thinking peanut worm in the first pic and sea cucumber in the second.

 

Looks like a Peanut worm or big spaghetti worm.
