The blue mussel, ''Mylius edulis'', is a type of [[shellfish]] known for its blue shell.  They live off the coast of [[North America]]n from [[Canada]] to [[North Carolina]].  They are used in culinary purposes, and can be steamed or smoked.  Each filters between 10-15 gallons of water per day.  At one point, Canadians who ate blue mussels form off [[Prince Edward Island]] became sick, experiencing short term amnesia from amnesic shellfish poisoning.[http://www.ocean.udel.edu/mas/seafood/bluemussel.html]

The blue mussel is one example of rapid, short-term evolution.  As the result of the Asian shore crab eating the blue mussel, they developed a thicker shell.  Researchers were able to use a distinct population of blue mussels that did not have the [[Asia]]n shore crab as a predator as a control that did not have the corresponding change in shell thickness.  Because the control group was not naturally selected to have a thicker shell thickness, they did not evolve.[http://evolution.berkeley.edu/evolibrary/news/060901_mussels]
