Freshwater mussels

On Thursday we took a 2 mile canoe trip, on the way we stopped to look at freshwater mussles with Jerry. He showed us the different species in the area including the endangered northern Riffeled Shell. We saw how in some mussles different colors are present but they aren't sure why yet. My favorite shell that i saw had a greenish-blue circle on one side and a purple on the other. We saved a few mussles from drying out. There were mussles in the shallow water who needed to be burried in the deeper water. When putting back a mussle you put the muscular foot side down in the muck and leave part of the hinge out inorder for the mussles to filter-feed.
