Can you tell the age of an oyster by the size of its shell?

It is not possible to accurately determine the age of an oyster by the size of its shell. While it is true that an oyster's shell grows with age, the growth rate of the shell is not constant and can be influenced by several factors such as water temperature, salinity, food availability, and even disease.

Moreover, the growth rate of an oyster's shell can vary depending on the species of oyster, making it even more difficult to determine its age based on its shell size.

There are other methods that can be used to estimate the age of an oyster, such as counting the growth rings on the shell or using internal shell layers, but these methods can also be imprecise and require specialized equipment and expertise.
