To sum up where we have found green mussels, all the symbols represent a location where green mussels were collected.  The difference between symbols is simply who collected them, which includes USGS, FMRI, Mote Marine Lab, TECO, and the US Coast Guard. We have found them as far north as Johns Pass in St. Petersburg and as far south as Boca Grande outside Charlotte Harbor.  We don’t know the complete range as mussels were collected as the outermost sites we sampled. Blue dots are Mote Marine collections.
