What the heck is this?

I had a clam that I brought home from the gulf that has been in my tank for a few months..well it died some time between last night and this afternoon and was eaten...so i took the shell out (it wasnt a fancy clam or anything) well about an hour or so after i took the shell out..i saw this where there clam used to be...what is it? Looks like a paint brush...doesnt have a tube like a feather duster...that i can see anyways.. any guesses? it is next to one of my king crown snails...

 

is it the clams tendons it used to hold on to that area (forgot the name for it)? thats my best guess or its some kinda of algae the clam blocked out.

 

I agree it's likely the foot of the clam

It's called the clam's byssus, or byssal threads.

Cheers,
