Zebra Mussels and Quagga
Zebra (Dreissena Polymorpha) and Quagga (Dreissena Bugensis) mussels are two species from the genus known as Dreissena. Both of these mussels look very similar, but when you give them a closer look you can tell the differences between the two. The zebra mussels are triangular and have a flat side and sharp edges. Quagga mussels have rounder sides and do not have sharp edges. They also have dark rings on the shell and are kind of pale near the edge. These two mussels are found mostly in the great lakes, also found inland lakes and waterways in twenty states, as well as Ontario and Quebec. The landed there after strong water currents hit transoceanic ships that were carrying vilegers, juveniles, or adult mussels. They could’ve also come form-fishing activities that let them be transported over land this could be hard, knowing that mu
ssels aren’t able to live out of the water for long periods of time. (Richerson, 4) I didn’t find any weaknesses in the experiment performed. Expect maybe that we measured them after they were all dried out and easy to break. Maybe if we measured them in their bivalve stage, there would be a different out come to the experiment. Question – is there a difference between Zebra mussels and quagga mussels?
