Copano Bay has several oyster reefs, and several of the beaches around the bay have lots of shells, most of them of Eastern Oyster, Crassostrea virginica. There are shells of many other species on the beach at this location, but typically the oysters are more numerous and have the largest shells.

I did not observe live oysters at this location, but I did see several nearby during a research cruise to Copano Bay on a different date.

Read more about this species in Tunnell et al (2010)’s Encyclopedia of Texas Seashells, page 321, and in the upcoming Texas Seashells, A Field Guide, on page 169.
