found some recruits on ceramic tiles placed out in Crissy Marsh about a month ago. Also found some shells on various structures throughout the marsh. Some really close to the Tennessee Hollow watershed outlet (cement culvert) into the marsh.
I presume both the NZ and Pacific rock oyster are present in the area
C.nippona or C.gigas
Here's a new bivalve for me, a fluted, many-layered striped burgundy and white shell. It looks kind of like an oyster shell. These are two separate specimens, both found on rocks during the minus tide. One is under water.
