Black sandshell or Spike?

For the past 7 or so years I have enjoyed surveying for and learning about freshwater mussels, one of the most interesting and at-risk groups of native organisms. I would highly recommend checking out the Unio Gallery for some great video on the amazing reproduction techniques of freshwater mussels. Anyway the field notes above are from a day spent in the Grand River of northeastern Ohio, both of these very similar looking mussels are present in the Grand.
