The giant clam (Tridacna gigas) is – you guessed it – humongous! It is the largest of all bivalve mollusks in the world, reaching lengths of more than 4 feet, and they can live for nearly a century. Description Giant clams have multiple vertical folds in their thick, heavy shells that give them their characteristic wavy opening.Clams are bivalves meaning they have shells consisting of two halves, or valves.. The valves are joined at the top, and the adductor muscles on each side hold the shell closed. If the adductor muscles are relaxed, the shell is pulled open by ligaments located on each side of the umbo.. The clam's foot is used to dig down into the sand, and a pair of long siphon s that extrude from the clam ...CLAM BODY SYSTEMS.

In most ...What kind of body symmetry does a clam have? Each valve of Nuculopsis (right drawing, “Bilateral symmetry (clam)”) is nearly a mirror image of the other, so that the plane of symmetry lies along the line at which the valves join, called the line of commissure. This is true of most clams. Brachiopods are quite different.Symmetry of roundworm. bilateral. Symmetry of Crayfish. bilateral. Symmetry of grasshopper. bilateral.

A clam is a bivalve mollusc that has a soft body enclosed by two hard shells. Clams are found in marine habitats all over the world. Most clams live buried in sediment, and feed by filter-feeding. Clams have a radial symmetry, meaning that their body can be divided into equal halves by any number of radial lines that pass through their center ...

In nature, the examples of line symmetry are only very, very close to exact. They are not perfect. This ‘closeness’ is referred to as ‘near symmetry’ or ‘approximate symmetry’. What is Symmetry? The butterfly is a great example of line symmetry in the natural world. This animation is perfect for demonstrating bilateral symmetry.

Clams, Snails, and Squid: Phylum Mollusca, Class Pelecypoda. Pelecypods have two shells, or bivalves, that protect the soft parts of the animal.
