Many different types of clams live in the Bay. Fish Fish like other vertebrates, have a backbone but they breath through gills. Parasites may cling inside their gills. A pair of pectoral and pelvic fins help steer while dorsal and anal fins stabilize. The swim bladder, located in the body cavity, makes the fish almost weightless in water.
Scales provide protection and camouflage.
The first two or three pairs of legs are pinchers. The last pairs are used for swimming. Shrimp are mainly bottom dwellers, living among algae, sea grasses, stones and shells. They help breakdown algae and grasses by consuming bits of detrital fragments. Oysters Oysters are mollusks with two valves, the bottom one being deeper, heavier and cup shaped.
