What looks like a striped fish with several tails is actually the opening of the mussel shell which is hard to see.

Did You Know?
Mussels rely on fish to carry their young around until they are old enough to drop to the river bottom. To attract the fish and attach their young, mussels put on displays that make fish think they are fish or other food. The mussel shell, which is all we normally see, is now barely visible.
