Univalves category classification of Seafood

These are recognized by the characteristic spiral formation of their shells, which unlike those of bivalves, are not divided into halves e.g. Whelks, Winkles etc.

Bivalves

These have two distinctly separated shells joined by a hinge-like membrane. The movements of shell are controlled by a strong muscle.

When the muscles relax, the two halves of the shell fall open.

The shell also opens when the organism dies, thus exposing the contents of the shell to contamination from outside, e.g. Oysters, Scallops, Mussels, Clams and Cockles.
The shells of the Molluscs increase at the rate of one ring per year to allow for the growth of the organism.

The age of the molluscs can thus be roughly estimated by the number of the rings on the shell.

b. Crustaceans

These have a segmented crust like shell e.g. Lobster, Crabs, Prawns, Shrimps, Crayfish (has claws), Crawfish (has no claws).

Lobster

The shells of the crustaceans don’t grow with the fish, unlike those of the Molluscs, but are shed each year, with a new one forming to suit their new size.
