All of these animals are found all over the world and in both saltwater and freshwater. Furthermore, they are one of the most commonly eaten kinds of seafood.
The most significant aspect of the anatomy of the bivalves is their two shells, which protect its soft inner body. Furthermore, bivalves may open and close their shells to move and eat. Nevertheless, in the presence of danger, they can close immediately.
You may ask, how do they move? Well, they have a special muscle in them known as the foot, which works like a pivot that controls the shells and is responsible for most of the movements of the shell. Moreover, this foot is also especially effective when moving side to side and digging to help the bivalve in burrowing itself into the sand away from any danger. For some other types of movements, bivalve mainly depends on the current of the water in order to help in carrying them extra distances.
Rather than a mouth, bivalves possess tubes known as siphons, which allow them to eat and breath. The food passes through the stomach where the digestion takes place. The oxygen from the water is then goes through the gills, which help in respiration. The carbon dioxide and the waste products are eliminated as well. This is through another siphon –known as ‘out-current siphon’.
