Turns out, some places use clams and mussels to test how clear the water is

While most people probably think of clams and mussels as a part of some fancy dinner, it appears they have a much higher significance in some places. For example, the water quality in Warsaw, the capital city of Poland, is monitored by… well, yes, clams. A Polish Tumblr user who goes by nickname Ftgurdy explained that the city of Warsaw gets its water from a river and “the main water pump has 8 clams that have triggers attached to their shells. If the water gets too toxic, they close, and the triggers shut off the city’s water supply automatically.” There’s a whole documentary on that, called Fat Kathy, and you can check out its trailer here. It follows how the main scientist-malacologist watches over the system’s operation. The film is described as “a philosophical essay on the dependence of people from nature and the world around them.”
