Did you know?

Seashells are made by mollusks.  Mollusks are invertebrates (or animals with no backbone) that produce shells of one or two pieces.  These shells either wholly or partly enclose a soft body of a mollusk. In the marsh, campers typically find a variety of mollusks that are divided into two groups: gastropods or univalves, and bivalves. 

 

Let’s take a closer look at the gastropods and bivalves we find in the marsh.
