Not sure, I would think it has to do with their size.
One way that scientists determine age is by providing the clams with marked calcium that they make their shells with. They determine how much of the shell is produced in a certain amount of time, then extrapolate the age by determining how much shell the clam has and how long it would have taken the clam to make it.

the rings on the shell... just like a tree, the clam also grows yearly. You can tell by the number of bands it has on it starting from the hinge.
