What are some "funky" organisms living in estuaries?

Question

funky as in having an interesting tale, or lifestyle, or its wierd relationship with another organism, maybe even the unusual place it calls home within the estuary

Answer 1

The nutria is a pretty interesting little critter -- used to see them all the time while duck hunting in the wetlands around SE Texas/SW Louisiana.

Answer 2

I once saw a human living in a dumpster sharing the domicile with some rats. When I asked him what he was doing in there, he said, "It is my home." I hope this helps.
