Bivalves such as clams, oysters, muscles & scallops are classed as molouscs but what makes them different form other molluscs is a latteral pair of hinged shells. In the seas and esturies of the world there are about 20,000 species of bivalves, the largest and most impressive being the giant clam which has a shell span of 4’ when fully grown.

When a predator or threat comes too close for comfort these amazing creatures can close up firmly or swim away. Scallops being the most accomplished swimmers can move at great speed.

Bivalves often dwell on or in the substrate and some types such as muscles will prefer to anchor to a hard surface. They are predominantly filter feeders witch strain a mixture of bacteria, protozoa, algae and larvae from the water column.

In the home aquarium feeding these creatures a variety of liquid foods is paramount to their survival and the aquarist should be very careful not to over filter. These are beautiful creatures who make a stunning and interesting addition to any marine aquarium.
