Bivalves have a long history. Their fossils first appear in rocks that date to the middle of the Cambrian Period, about 510 million years ago.Bivalves are molluscs, well-known to humans who have developed a taste for many of them. This group includes oysters, mussels, pipis, cockles, scallops and clams. The name bivalve means 'two valves'. The soft-bodied animals live inside the shell valves, which are joined together by a toothed hinge and a flexible ligament. In geometry, symmetry is defined as a balanced and proportionate similarity that is found in two halves of an object. It means one-half is the mirror image of the other half. The imaginary line or axis along which you can fold a figure to obtain the symmetrical halves is called the line of symmetry. If an object is symmetrical, it means that it ...

Body Plan. In a typical sea star, it is easy to see the classic five-fold symmetry that is characteristic of echinoderms. This includes arms projecting outwards around a centralized axis. Even sea cucumbers, which show a more worm-like appearance, usually exhibit this body plan, known as pentameral symmetry.Near Symmetry in Nature. The difference between symmetry in the animal world and the symmetry of Math Class drawings needs to be noted. In math lessons the symmetry examples given are usually perfect. Every diagram has one side the EXACT mirror image of the other. In nature, the examples of line symmetry are only very, very close to exact.Bivalvia. Also known as pelecypods, the approximately 15,000 species of this taxon are found in marine and freshwater habitats throughout the world.
