Scientists themselves oldest quahog catch it to examine the effects of environmental changes, such as salinity, availability of food, temperature of sea water, and climate change on the lives of marine biota.
Scientists determine the age of quahog shells based on circle patterns are often called growth rings, the same as found in the tree.
Circular pattern is formed due to differences in shell growth during summer and winter. In the summer, a lot of food available so that the shell grows rapidly while in winter the opposite.
