Who knew?

The East Kozmino Bay, a body of water east of Moscow is soon going to be home to a scallop garden to detect contaminants in the water. Who knew those little guys could do such a thing? It is the first Russian port to use the mollusks as a water-monitoring instrument. They can detect oil and heavy metal, and if detected they will imbibe it back to clean water. How cool is that to have such environmentally sanitary capabilities?
