The term ...These clams, outstand among other species; for having the capacity to withstand very cold temperatures, almost close to freezing. On the other hand, their high life expectancy, which is around 10 years of age, represents another distinctive feature in these creatures.. The freshwater clams are considered filtering animals, since they have the …This symmetry is evident in their body plan, which typically features a head with sense organs, a central nervous system, and a distinct left and right side. Clams are a type of bilaterian, and are thus distinguished by these characteristics. Clams are also notable for their two shells, which are hinged along this central axis and open and ...

Gastropods such as Conus are not bilaterally symmetrical, that is, as the snail grows, its shell coils about a vertical axis. This spiraling growth can be in one of two directions, either right-handed (dextral) where the aperture of the shell is on the right or, much more rarely, sinistral if on the left.The line drawing below is helpful in illustrating the differences in symmetry between pelecypods and brachiopods. 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.
