Comments
This specimen and dozens like it were collected from matrix material deposited in the waters of the Chesapeake Bay by a landslide. It is one of only a few species that consistently survived intact in the matrix samples I collected. These are also common finds loose on the beach. This specimen was donated to the Delaware Museum of Natural History.
